Explain structured changes in a registered public document: JSON Pointer changes, HTML block changes and deterministic significance hints. Use instead of Check when a changed/unchanged flag or short text diff is insufficient. First obtain watch_id with free fresh402_register; saved URL/rules are reused. compare_to is previous (default) or baseline; previous_hash overrides it when the same-watch snapshot is retained. Up to 200 changes; legacy HTML may have text-only fidelity. No LLM, JavaScript rendering or complete API compatibility guarantee. $0.015 USDC per call on Base mainnet (eip155:8453); requires an x402-capable MCP payment client and funded native-USDC payer, otherwise returns a payment challenge. Alternatively use prepaid credits through REST or this MCP tool: X-Fresh402-API-Key in HTTP, with params._meta["fresh402/prepaid"] containing idempotency_key, tariff_version and max_credits. When root mpp_payments.enabled is true, native MPP EVM charge is another option at the same USDC price: use an authorized Base EIP-712 signer and official mppx client, org.paymentauth/credential metadata and a persisted private recovery token. MPP receipt: org.paymentauth/receipt; see docs/MPP.md. Never combine MPP, prepaid and x402. Discover packages at /v2/prepaid/plans; see docs/AGENT_PREPAID.md for browserless wallet enrollment, bounded early credits and recovery. Optional Circle Gateway x402 is available only when root circle_gateway.enabled is true. Use the GatewayWalletBatched quote, a funded Base Gateway EOA and a persisted private recovery token. Pending batches return 409; replay the original proof/input/token after 60 seconds. Results require Gateway confirmed/completed evidence; never mix providers. No Circle prepaid funding. See docs/CIRCLE_GATEWAY.md.
