Tools

• assess_counterparty_risk

  Return a decision-ready counterparty-risk verdict for an EVM address before funds or authority are committed. The result branches to high_risk, caution, acceptable, or insufficient_data with the evidence needed for the calling agent to act. Use when: Delegate this check before sending funds, granting approvals, or interacting with an unknown EVM address when the caller needs a bounded risk decision. Limitations: Analytics and heuristic risk assessment; not a credit bureau, fraud guarantee, or legal endorsement. Relies on DeBank indexing and on-chain Aave/Compound contract states. Alternatives: get_wallet_approvals, get_liquidation_risk, get_wallet_positions

  shallow
• assess_market_resolution

  Return a decision-ready resolution-risk verdict for one Polymarket market before an agent trades, quotes, or forecasts it. The result branches to tradeable, ambiguous, avoid, or insufficient_data and names the resolution basis (price_feed, official_source, media_consensus, unspecified), UMA dispute state, rule-wording risks, and executability (liquidity, spread) so the calling agent can act without reading the full rules. Use when: Call once per market before placing, quoting, or forecasting a Polymarket position when the caller needs to know whether the rules and resolution state make the outcome well-defined. Repeat calls within two minutes return cached data. Limitations: Heuristic analysis of Polymarket rule wording and Gamma API state; not a probability forecast, legal advice, or a guarantee of how UMA voters resolve. Does not read order-book depth, event-level augmented negative-risk settings, or clarifications published off-platform. Alternatives: web_search, http_fetch

  shallow
• calculate

  Evaluate a safe arithmetic expression and return the numeric result. Supports +,-,*,/,**,%,sqrt,abs,round,floor,ceil,log,sin,cos,tan,pi,e. Use for derived figures (ratios, differences, percentages) that no tool output already provides. Use when: Use when an agent must derive a value that tool outputs do not already include, such as a ratio, spread, or percentage. Do not use to re-derive pre-computed fields like std_30d or dca_baseline_90d that get_token_price_historical returns. Limitations: Arithmetic only — no aggregation over tool history, no unit conversion, and no financial modeling beyond the listed functions. Errors return an error field rather than raising. Alternatives: get_token_price_historical, get_datetime

  shallow
• convert_currency

  Convert an amount between fiat currencies (USD, EUR, GBP) and crypto assets (BTC, ETH, USDC, SOL) and return the converted amount plus the exchange rate used. Use when: Use when an amount must be expressed in a different currency than the source data — for example converting a USD portfolio value into EUR, or a fiat amount into its crypto equivalent. For prices only, get_token_price returns the rate directly without a second call. Limitations: Spot-rate conversion at request time; no historical or forward rates, and no slippage or fee modeling. Actual swap execution differs — use get_dex_quote for executable on-chain quotes. Alternatives: get_token_price, get_dex_quote

  shallow
• count_text_stats

  Return word, character, sentence, and paragraph counts plus average words per sentence for a given text, for length checks and content sizing decisions. Use when: Use when output length must be validated or reported — e.g. verifying a summary meets a length contract or comparing document sizes. Do not use for semantic summarization; it counts only. Limitations: Pure counting on the provided text — no language detection, no reading-level or sentiment analysis, and no retrieval of external content. Alternatives: web_search, http_fetch

  shallow
• decode_transaction

  Decode a transaction's calldata into a human-readable function name and arguments, and return transaction status (1=success, 0=revert), gas used, and block number. Uses a supplied ABI when provided, otherwise 4byte.directory. Supports Ethereum mainnet and Base. Use when: Use when one known transaction must be explained — what function was called, with what arguments, and whether it succeeded. For wallet-wide activity patterns use get_wallet_history instead. Limitations: 4byte.directory matching can be ambiguous or absent for custom contracts; supply an ABI for precise decoding. One transaction per call; Ethereum mainnet and Base only. Alternatives: get_transaction, get_wallet_history

  shallow
• delegate_to_agent

  Delegate a task to a remote A2A-compliant agent: discover its capabilities via its agent card, send it a message, handle payment, and return the result. Use only when no local platform tool can fulfil the request. Use when: Use when a task requires specialist capabilities beyond the local tool set. Call discover_agents first when the remote agent URL is unknown. Do not retry unchanged after error_type=advertised_price_exceeds_cap; pick another result or adjust the cap. Limitations: Requires an allowlisted remote URL and sufficient delegation budget; the remote agent's price and capability claims are read from its card and are not independently verified. Involves real payment. Alternatives: discover_agents, web_search

  shallow
• discover_agents

  Find opt-in remote A2A agents, published tool capabilities, endpoints, and public reputation status. Use when: Use before delegate_to_agent when a specialist agent is needed but its URL is unknown. Limitations: Discovery is read-only and does not add an agent to the org allowlist; delegate_to_agent remains authoritative. Alternatives: delegate_to_agent

  shallow
• get_block

  Get block details (timestamp, gas used, base fee, miner, transaction count) for an Ethereum or Base block by number, hash, or 'latest'. Use to anchor events to a point in chain time. Use when: Use when a question depends on when a block occurred, how full it was, or its base fee — for example dating a transaction or checking congestion at a specific height. For current fee levels use get_gas_price instead. Limitations: One block per call; Ethereum mainnet and Base only. Historical base fee data depends on RPC node retention for older heights. Alternatives: get_transaction, get_gas_price

  shallow
• get_chain_metrics

  Compare blockchain ecosystem health via DeFiLlama: current TVL, 7/30-day TVL change, and aggregate fee activity. Pass chains such as ['Ethereum', 'Arbitrum', 'Solana'] for a focused comparison, or omit chains to inspect the highest-TVL ecosystems. Use when: Use for ecosystem-level comparisons — which chains are growing, where fee activity concentrates, or how a chain's TVL trended. For a single protocol's economics use get_protocol_tvl instead. Limitations: Third-party DeFiLlama analytics; historical and fee fields fail open (null) for uncovered chains. Not a real-time measure of chain throughput or security. Alternatives: get_protocol_tvl, get_dex_volume

  shallow
• get_datetime

  Return the current UTC date and time as a formatted string and ISO 8601 timestamp, for grounding time-relative reasoning in the actual clock rather than training-data assumptions. Use when: Use when a task must anchor on the current date or time — computing ages, windows, deadlines, or 'as of today' context. The runtime context block already states the date, so call this only when a specific strftime format or a precise timestamp is needed. Limitations: UTC only — no timezone conversion. An unsupported strftime format silently falls back to the default format instead of erroring. Alternatives: calculate, get_block

  shallow
• get_defi_positions

  Block-accurate DeFi positions for a wallet across Aave v3, Compound v3, Uniswap v3 LP, and Lido on Ethereum or Base. Returns Aave account health (collateral, debt, health factor, LTV) with per-reserve breakdown, Compound v3 market positions, Uniswap v3 LP positions by token ID, and on Ethereum the Lido stETH/wstETH balances with the current wstETH-to-stETH equivalent. Per-protocol failures are isolated — other protocols still return. Use when: Use when a block-accurate single-wallet protocol snapshot is needed, including health factor and LP position detail. For broad all-chain discovery or net worth across many protocols use get_wallet_positions instead. Limitations: On-chain RPC view of four protocol families on Ethereum and Base only; does not discover wallets' unknown or long-tail protocol positions. Compound v3 reports only a boolean liquidation flag — never state a numeric Compound health factor. Errors list which protocols were unavailable. Alternatives: get_wallet_positions, get_liquidation_risk, get_wallet_portfolio

  shallow
• get_dex_quote

  Get the best Uniswap v3 swap quote on Ethereum (chain_id=1) or Base (chain_id=8453) via direct on-chain QuoterV2 calls. Queries all four fee tiers (100/500/3000/10000 bps) in parallel and returns the tier with the highest output amount, along with per-tier breakdown. Inputs are raw uint256 amounts and EIP-55 checksummed addresses; native ETH is not quoted directly — pass the WETH address. Returns no_liquidity=true when no pool exists for the pair. Point-in-time quote at the returned block_number; do not cache. Use when: Choose when you need a best-execution Uniswap v3 swap quote on Ethereum or Base before executing a trade — e.g. price impact, output amount, or route selection. Limitations: Quotes raw uint256 amounts with EIP-55 checksummed addresses only; native ETH is not quoted directly (pass WETH). Point-in-time at the returned block_number — do not cache. Alternatives: get_token_price, get_dex_volume

  shallow
• get_dex_volume

  Compare decentralized exchange activity via DeFiLlama: 24h/7d/30-day volume, period-over-period changes, and each protocol's share of reported global 24-hour DEX volume. Filter by protocol and rank by a 1-, 7-, or 30-day lookback window. Use when: Use for landscape questions — which DEXs dominate volume, how activity shifted week-over-week, or a specific protocol's relative share. For executable swap pricing use get_dex_quote instead. Limitations: Third-party DeFiLlama reporting, not on-chain truth; coverage gaps understate smaller protocols. 24-hour share is computed against the unfiltered global total, so filtered results retain landscape context. Alternatives: get_dex_quote, get_chain_metrics

  shallow
• get_erc20_balance

  Get the exact on-chain ERC-20 balance of a wallet for one token contract, normalized by decimals and returned with the token's symbol. Use for a precise single-token check. Use when: Use when a specific token contract's balance must be verified block-accurately — e.g. confirming funds before an approval or transfer. For a multi-asset portfolio view use get_wallet_portfolio instead. Limitations: One token contract per call on Ethereum or Base; the contract address is required, so unknown tokens cannot be looked up by symbol. Returns raw balance data only — no USD valuation. Alternatives: get_wallet_portfolio, get_eth_balance

  shallow
• get_eth_balance

  Get the exact on-chain native ETH balance of an address on Ethereum or Base, in wei and ether. get_wallet_portfolio already includes native ETH in its holdings — call this only for a standalone balance without a portfolio scan. Use when: Use when a wallet's gas-availability or standalone ETH amount must be verified block-accurately. Do not call after or alongside get_wallet_portfolio — the holdings list already includes native ETH. Limitations: Native ETH only; ERC-20 balances require get_erc20_balance. Requires an EIP-55 checksummed address. Ethereum mainnet and Base only. Alternatives: get_wallet_portfolio, get_erc20_balance

  shallow
• get_gas_price

  Get current EIP-1559 gas fees on Ethereum or Base: base fee, priority fee, next-block base fee estimate, and congestion (gas_used_ratio >0.5 busy, >0.9 very congested). Optional USD estimates cover a simple transfer and a swap-like transaction. Cached 10 seconds per chain. Use when: Use before advising a transaction — to time execution, size a gas budget, or judge congestion. Call once per decision; the 10-second cache makes rapid re-calls pointless. Limitations: Point-in-time estimate that changes every block; USD figures are rough heuristics at 21k/150k gas, not an execution quote. Ethereum mainnet and Base only. Alternatives: get_block, get_dex_quote

  shallow
• get_lending_rates

  Get current on-chain lending supply/borrow APYs for Aave v3 reserves and Compound v3 markets on Ethereum or Base, with per-asset snapshots and Compound utilization. Use for protocol-specific yield comparisons such as USDC on Aave vs Compound. Use when: Use for protocol-specific lending-rate questions (e.g. 'Aave vs Compound USDC rates'). Prefer over get_yield_rates when the protocols are known; use get_yield_rates for broad pool discovery across many protocols. Do not fall back to web_search when this returns errors — report them. Limitations: On-chain snapshots of Aave v3 and Compound v3 on Ethereum and Base only; not a multi-protocol yield aggregator. Rates are point-in-time and change per block. Returns an errors list — report each unavailable protocol explicitly and treat empty rates with empty errors as transient RPC unavailability. Alternatives: get_yield_rates, get_defi_positions, get_liquidation_risk

  shallow
• get_liquidation_risk

  Assess DeFi liquidation risk for up to 50 wallets across Aave v3 and Compound v3 on Ethereum or Base. Returns per-wallet health factor, tiered risk classification (liquidatable, critical, warning, caution, healthy, no_debt), and an overall_tier aggregate. Per-protocol failures are isolated — one protocol's RPC error does not blank the other's result. Use when: Use for multi-wallet batch risk assessment (2+ wallets). For a single-wallet DeFi analysis use get_defi_positions, which already includes risk metrics. Use assess_counterparty_risk when the question is counterparty trust rather than position health. Limitations: View-only scan of Aave v3 and Compound v3 on Ethereum and Base with hardcoded market addresses; not a liquidation simulation or guarantee. Compound v3 exposes only a boolean liquidation flag — no numeric health factor. Duplicate wallet addresses are silently removed. Alternatives: get_defi_positions, assess_counterparty_risk, get_wallet_positions

  shallow
• get_protocol_tvl

  Get Total Value Locked for one or many DeFi protocols from DeFiLlama: current USD TVL, 7/30-day change, fees and revenue when reported, per-chain breakdown, and optional daily historical series. Batch multiple protocols via protocols=[...] — batch responses return one compact economic summary per protocol; single-protocol calls add chain and historical detail. Supports 3,000+ protocols; use DeFiLlama slugs ('aave-v3', 'uniswap-v3'); common aliases are auto-corrected. Use when: Use for protocol-level economic questions — size, growth, fees, or revenue of a specific protocol. For 2+ protocols always batch in one call rather than calling per-protocol. Pass include_historical=true with days when a trend is needed; without it the response is a current TVL scalar. For ecosystem-level chain comparisons use get_chain_metrics instead. Limitations: Third-party DeFiLlama analytics, not on-chain truth. Upstream revenue failures surface as revenue_error_type and null economic fields are data gaps — never fabricate values for them. Alternatives: get_chain_metrics, get_yield_rates, get_dex_volume

  shallow
• get_token_approvals

  Block-accurate audit of ERC-20 allowances for a wallet across curated DeFi spenders (Uniswap, Aave, Compound, 1inch, 0x, OpenSea) on Ethereum or Base. Flags unlimited approvals by risk level (high=unknown spender, medium=trusted protocol, low=bounded). Use before swaps or after security incidents to detect active exploit vectors. Use when: Use for a free, block-accurate Ethereum/Base check of an address's exposure to the curated spender list. For broad all-chain spender discovery, hacked/abandoned flags, or NFT-adjacent exposure use get_wallet_approvals instead. Limitations: Covers only the tracked-asset registry and curated spenders — untracked tokens and custom spenders are excluded. Does not inspect NFT approvals or off-chain Permit2 sub-permits. An error field marks results as incomplete rather than clean. Alternatives: get_wallet_approvals, assess_counterparty_risk

  shallow
• get_token_price

  Get current price, 24h change, market cap, FDV, and volume for one or more crypto tokens. Accepts ticker symbols, full names, or CoinGecko IDs; unknown symbols resolve automatically. Batch up to 50 tokens. Reuse price_usd/value_usd already returned by get_wallet_portfolio instead of re-calling. Use when: Use for spot pricing of named tokens — including batched multi-token queries. Do not call for tokens whose price get_wallet_portfolio already returned, or for address-only unknown tokens (report them as unrecognized). For historical windows use get_token_price_historical. Limitations: CoinGecko spot data; point-in-time and not an executable swap quote. Bare 0x addresses are not resolvable and should be treated as unknown tokens. Alternatives: get_token_price_historical, get_wallet_portfolio, get_dex_quote

  shallow
• get_token_price_historical

  Get historical crypto prices over a 1–365 day window: period statistics (start, end, % change, high, low), a downsampled daily series, high_30d, std_30d, and dca_baseline_90d. Use for period comparisons and trend analysis; prefer over web_search for time-comparative financial queries. Pass stats_only=true when the daily series is unnecessary. Use when: Use for time-comparative financial questions — month-over-month, YTD, volatility, or DCA baselines. Prefer over web_search for such queries. Use the pre-computed stats directly; do not re-derive them with calculate. Limitations: Daily granularity (downsampled), max 365-day window, CoinGecko coverage only. Check dca_baseline_90d_partial before relying on the baseline — incomplete history yields a partial baseline. Alternatives: get_token_price, web_search

  shallow
• get_transaction

  Get details and receipt for one Ethereum or Base transaction by hash: bounded calldata, normalized event logs, transaction index, and receipt-derived effective gas price and fee when available. Use to verify a specific transaction's status and outcome. Use when: Use when one known transaction must be verified — status, logs, gas paid, or execution outcome. To understand what the calldata means use decode_transaction; for wallet-wide activity use get_wallet_history. Limitations: One transaction hash per call on Ethereum or Base; pending transactions may not resolve yet. Calldata is returned bounded, not decoded — use decode_transaction for semantic decoding. Alternatives: decode_transaction, get_block, get_wallet_history

  shallow
• get_wallet_approvals

  Inspect a wallet's current ERC-20 token authorization exposure on one DeBank-supported chain. Returns discovered spenders, USD exposure, protocol attribution, and hacked or abandoned protocol flags. This is broader than the curated block-accurate get_token_approvals tool. Use when: Use when broad spender discovery or cross-chain security screening is needed. Call once per chain because DeBank requires a chain_id. Use get_token_approvals for a free, block-accurate Ethereum or Base scan of curated tokens and spenders. Limitations: The result is third-party analytics and may be stale. It covers token approvals only, not NFT approvals or off-chain Permit2 sub-permits; each chain consumes a separate billable provider call. Alternatives: get_token_approvals

  shallow
• get_wallet_history

  Get one page of decoded transaction history for an EVM wallet across DeBank-supported chains. Returns send, receive, and approval categories with protocol, token, exchange, gas, and USD metadata. Use the returned next_cursor as start_time to page backward. Use when: Use for wallet activity discovery, protocol interaction history, exchange exposure, and gas analysis. Page backward with next_cursor for older activity. Use get_transaction or decode_transaction when one known transaction needs block-level details. Limitations: DeBank returns at most 20 entries per call and the data may be stale. This tool is not a complete ledger, PnL engine, or cost-basis calculator because historical execution prices and all transfer semantics are not guaranteed. Alternatives: get_transaction, decode_transaction

  shallow
• get_wallet_portfolio

  Get aggregated token holdings with USD values for a wallet address. Tracks 19 major assets on Ethereum and 12 on Base, including spot, lending, liquid-staking, restaking, and stablecoin assets. Sorted by USD value. Returns up to 20 holdings. Includes native ETH balance in the holdings list — calling get_eth_balance separately after this is redundant. Use when: Choose when you need a wallet's overall token exposure and USD value on Ethereum or Base in one call. Call once per chain for a cross-chain comparison. Limitations: Tracks a fixed set of major assets per chain, not arbitrary tokens. Returns up to 20 holdings. Native ETH is included, so calling get_eth_balance separately is redundant. Alternatives: get_eth_balance, get_token_price, get_defi_positions

  shallow
• get_wallet_positions

  Get a wallet's DeFi positions across all DeBank-supported chains and protocols. Returns protocol-level positions, asset/debt/net USD values, optional token lists, aggregate exposure, and optional all-chain net worth. Set include_token_balances=true to also return DeBank's complete cross-chain wallet token list. Set include_token_lists=false for a compact balance and debt summary without nested position tokens. This covers substantially more protocols and chains than the block-accurate get_defi_positions tool. Use raw-RPC tools for liquidation, swap quotes, or other transaction-critical questions. Use when: Use for broad wallet discovery, portfolio allocation, protocol exposure, or cross-chain position questions. Set include_token_balances=true when complete wallet token discovery is required; otherwise the response only includes tokens attached to protocol positions. Set include_token_lists=false when only protocol balances, debt, or aggregate exposure are needed. Use get_defi_positions when the user needs a block-accurate Aave, Compound, Uniswap, or Lido snapshot. Limitations: DeBank portfolio data is third-party analytics and may be stale, including occasional long refresh delays. It is read-only, EVM wallet oriented, and does not prove current liquidation or execution state. include_token_balances adds a separate billable DeBank request; include_token_lists only changes response detail. Alternatives: get_defi_positions, get_wallet_portfolio, get_token_approvals

  shallow
• get_yield_rates

  Get DeFi yield pool rates from DeFiLlama across 1,000+ protocols and all chains: pools sorted by APY with TVL, base/reward APY, and 7d/30d mean APY context, filterable by protocol, chain, min TVL, min/max APY, and symbol. Returns up to 50 pools. For protocol-specific lending comparisons (Aave vs Compound) prefer get_lending_rates. Use when: Use for broad cross-protocol yield discovery. Call at most once per request — filter with min_apy, max_apy, min_tvl_usd, and symbols_any in a single call, then sort client-side rather than re-calling. For protocol-specific rate questions use get_lending_rates. Limitations: Third-party DeFiLlama analytics; up to 50 pools per call. The `symbol` field lists underlying tokens (e.g. 'ETH-USDC') — filter client-side instead of re-calling with different arguments. Reward APY indicates reward-dependent yield; do not present spot APY as durable. Alternatives: get_lending_rates, get_protocol_tvl, get_token_price

  shallow
• http_fetch

  Fetch a web page and return its main text content, cleaned of markup. Use to read articles, documentation, and other resources referenced by URL. Blocks private and cloud-metadata addresses and re-validates every redirect hop. Use when: Use when a known URL's content is needed and structured tools cannot answer — e.g. reading a linked document or API docs. For general factual lookup prefer web_search; for token prices prefer get_token_price. Limitations: Read-only GET-style extraction returning cleaned text, not raw HTML or binary content. JS-heavy pages may yield little content; private/internal network targets are deliberately unreachable. Alternatives: web_search, get_token_price

  shallow
• read_contract

  Call any view/pure function on a smart contract and return the decoded result, using a supplied ABI fragment. Supports historical reads via block_identifier and caller_address context for msg.sender-dependent views. Read-only: state-changing functions are rejected. Use when: Use when a protocol question needs a contract read that no higher-level tool covers — e.g. a niche view function or a protocol outside the standard tool set. Prefer purpose-built tools (get_defi_positions, get_lending_rates) for supported protocols. Limitations: Requires a valid ABI fragment; payable/nonpayable functions are rejected. Ethereum mainnet and Base only, with bounded RPC timeout and retry. Alternatives: get_defi_positions, get_lending_rates, get_token_approvals

  shallow
• record_predictions

  Record a complete structured prediction document for downstream evaluation. Call once with the exact machine-readable prediction; the human-readable report is provided separately. Use when: Use at the end of a scheduled analysis run to persist the machine-readable prediction for later scoring. Call exactly once with the complete prediction document — never partially or repeatedly. Limitations: Internal sink for scheduled analysis, not a caller-facing marketplace tool. Stores the prediction as given; no validation of prediction quality or deduplication across calls. Alternatives: get_datetime

  shallow
• resolve_ens

  Resolve an ENS name (e.g. 'vitalik.eth') to an Ethereum address, or an address to its primary ENS name, with avatar text record when available. Mainnet only. Use when: Use only when no 0x address is available and a name must become an address (or vice versa for attribution). If a 0x address is already present in the task or session, use it directly — resolution is redundant and adds latency. Limitations: Ethereum mainnet ENS only — no other chains or naming services. Reverse records are optional on ENS, so a valid address may legitimately have no primary name. Alternatives: get_wallet_portfolio, get_wallet_history

  shallow
• validate_opportunity

  Return a decision-ready yield-opportunity verdict before capital is deployed. The result branches to sustainable, caution, unsustainable, or insufficient_data and gives the calling agent the evidence needed to proceed, pause, or reject the opportunity. Use when: Delegate this check before deploying capital into a DeFi yield pool or staking opportunity when the caller needs an independent sustainability and liquidity decision. Limitations: Heuristic economic assessment based on DeFiLlama analytics and CoinGecko pricing. Does not audit smart contract bytecode, protocol governance, or admin key security. Alternatives: get_yield_rates, get_protocol_tvl, get_lending_rates, assess_counterparty_risk

  shallow
• web_search

  Real-time web search via Tavily for current events, fact-checking, and research. Use search_depth='advanced' for complex queries (higher quality, higher cost) and topic='news' or 'finance' for headlines or market information. Use when: Choose when the task needs current, external, or factual information not available from on-chain or local data — e.g. news, prices, documentation, or fact-checking. Limitations: Returns web snippets, not raw page bodies; results depend on Tavily coverage. Advanced depth costs more. Not a substitute for on-chain tools like get_token_price. Alternatives: get_token_price, http_fetch
