Tools

• diligence

  Combined counterparty due diligence in one call: runs sanctions screening on a crypto wallet (Chainalysis oracle — OFAC SDN, EU, UN) AND a UK Companies House KYB lookup (status, type, PSC / beneficial owners) in parallel. Built for compliance agents vetting a counterparty that has both an on-chain wallet and a UK company. Returns both independent results, plus an explicit disclaimer that no verified link between the wallet and the company is established by the data.

  shallow
• get_receipt

  Look up a public OCD receipt by its exact receipt_id (format "OCD-RCP-XXXX-XXXX-XXXX-XXXX"). Free, no payment. Returns the complete signed receipt envelope, or a structured not-found/unavailable reason -- never a guess. A private (unpublished) receipt and an unknown id are indistinguishable, both by design: this never confirms or denies that a private receipt exists.

  shallow
• inspect_allowance

  FREE. Deterministically inspect an ERC-20 allowance/revocation request against explicit network/token/spender/value policy. No wallet action, no signing, no chain read unless a separately requested preflight asks for it.

  shallow
• inspect_bridge

  FREE. Deterministically inspect a narrow Circle CCTP V2 Base-to-Ethereum native-USDC bridge request against explicit policy. No wallet action, no signing, no chain read.

  shallow
• inspect_payment

  FREE. Pure deterministic inspection of a proposed payment against structured policy (amount/network/asset/recipient/resource) — no external evidence, no sanctions screening, no cryptographic signing, no receipt. Returns the same ALLOW / REQUIRE_APPROVAL / BLOCK decision semantics as POST /x402/preflight-payment for the deterministic checks alone, so a caller can sanity-check a proposal before deciding whether the paid preflight (adds optional sanctions evidence and a signed, independently-verifiable receipt, $0.01) is worth paying for. This result is NOT cryptographically attested and carries no receipt — receipt is always null.

  shallow
• inspect_staking

  FREE. Deterministically inspect a narrow Ethereum Lido stETH submit request against explicit policy. No wallet action, signing, or chain read.

  shallow
• inspect_swap

  FREE. Deterministically inspect a narrow Base USDC-to-WETH direct Uniswap V3 swap against explicit policy. No wallet action or signing.

  shallow
• observe_allowance

  Given a signed OCD allowance preflight artifact and submitted Base transaction hash, independently inspect its canonical-USDC Approval event, Base safe-head finality, and historical allowance state. OCD never executes the transaction.

  shallow
• observe_bridge

  Given a signed OCD bridge preflight artifact, the Base depositForBurn transaction hash, and (once available) the Ethereum receiveMessage transaction hash, independently observe both chains, verify the CCTP message identity matches, and reconcile against the authorized action. Source-only observation is reported as an evidence gap, never as completion.

  shallow
• observe_staking

  Given a signed OCD staking preflight artifact and Ethereum transaction hash, independently inspect the canonical Lido Submitted event, transaction sender/value, optional minted shares, and Ethereum finalized-head finality. OCD never stakes ETH.

  shallow
• observe_swap

  Given a signed OCD swap preflight artifact and Base transaction hash, independently inspect direct Uniswap V3 exactInputSingle calldata, ERC-20 transfers, and Base safe-head finality. OCD never executes the swap.

  shallow
• preflight_allowance

  Call BEFORE an agent asks its wallet to approve or revoke a Base USDC ERC-20 allowance. OCD evaluates strict policy and returns a signed portable allowance artifact. ALLOW is policy only, never wallet authority.

  shallow
• preflight_bridge

  Call BEFORE an agent asks its wallet to bridge Base USDC to Ethereum via Circle CCTP V2 (depositForBurn). OCD evaluates strict policy and returns a signed portable bridge artifact. ALLOW is policy only, never wallet authority.

  shallow
• preflight_payment

  Call BEFORE an agent authorizes an autonomous payment. Evaluates it against your policy (max amount, allowed networks/assets, expected recipient, allowed origins) and returns a signed PREFLIGHT receipt -- ALLOW, REQUIRE_APPROVAL, or BLOCK, with reasons -- independently verifiable by anyone. Policy evaluation only: OCD never holds, moves, or authorizes funds. The wallet/x402 client separately authorizes execution after; ALLOW does not guarantee it will proceed.

  shallow
• preflight_staking

  Call BEFORE an agent asks its wallet to submit ETH to Lido stETH. OCD evaluates strict policy and returns a signed portable staking artifact. ALLOW is policy only, never wallet authority.

  shallow
• preflight_swap

  Call BEFORE an agent asks its wallet to execute a narrow Base USDC-to-WETH direct Uniswap V3 swap. OCD returns a signed portable policy artifact. ALLOW is policy only, never wallet authority.

  shallow
• screen_name

  OFAC name screening: fuzzy-match a person or company name against the official US Treasury OFAC Specially Designated Nationals (SDN) list (primary names + strong aliases). Returns scored candidate matches with the matched name, SDN type, and program. SCOPE: this is a screening aid for AML / KYC / sanctions compliance — a match is a candidate to investigate with secondary identifiers (DOB, nationality, ID), NOT a determination. Weak AKAs are not screened, per OFAC guidance.

  shallow
• screen_wallet

  Sanctions screening for a crypto wallet address. Checks an EVM address against the Chainalysis on-chain sanctions oracle, which covers OFAC SDN, EU, and UN designated addresses (including Tornado Cash and other sanctioned protocols). Returns a clear sanctioned / not-sanctioned result with the matching program. Use for AML compliance, counterparty due diligence, and payment screening before sending USDC or any funds to an address.

  shallow
• verify_receipt

  Independently checks whether a receipt is cryptographically VALID, INVALID, or UNVERIFIABLE, with a reason code. Free, no payment. Pass EITHER receipt_id (looks it up first, must be public) OR a complete receipt envelope you already hold (verified directly, no publication needed). This is a convenient ONLINE check -- it trusts this server to have honestly fetched the real signing-key registry. Running the same check yourself offline (the published @onchaindiligence/agent-evidence package) is a strictly stronger trust position; this tool does not replace that option.

  shallow
• verify_uk_company

  UK company verification and KYB (know-your-business) lookup via the official Companies House register. Given a UK company registration number, returns legal status (active / dissolved), company type, incorporation date, registered office address, and the people with significant control (PSC / beneficial owners). Use for KYB onboarding, supplier and counterparty due diligence, and confirming a UK business is real, active, and who controls it. Authoritative UK government open data.

  shallow
• verify_us_company

  US public company verification via the SEC EDGAR system. Given a ticker, SEC CIK, or company name, returns the registered entity name, CIK, industry (SIC code), state of incorporation, listed exchanges and tickers, business address, and most recent SEC filing. SCOPE: EDGAR covers SEC-registered PUBLIC companies and funds only — NOT private US companies, which register at the state level. Use for KYB and counterparty due diligence on listed US entities. Authoritative US government open data.
