How this service works
Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.
Output
Returns a JSON object containing on-chain evidence of whether the provided transaction hash satisfies the mandate context, including compliance status, transaction details, amount verification against authorized max, payee match, currency confirmation, and purpose attestation.
Example use cases
Agent payment compliance audit
“Verify that the Polygon transaction 0x7f3a...b92c actually matches my mandate: authorized max 25 USDC, payee 0xVendor789, purpose 'data enrichment service', and confirm it was an automated agent payment with no human present.”
Dispute resolution for overcharged mandate
“I need to check if transaction 0xdeadbeef...1234 on Base exceeded my authorized mandate of 10 USDC to payee 0xService111 for 'weather API calls' — can you pull the chain evidence and tell me if it was compliant?”
Human-present payment verification
“Validate that Ethereum transaction 0x9876...abcd was a human-approved payment up to 100 USDC to 0xMerchant555 for 'e-commerce checkout', flagged as human present, and that the on-chain evidence confirms the mandate terms were met.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/mandate-chain-evidenceWhen to prefer
Use this endpoint when an AI agent needs cryptographic or on-chain evidence that a payment mandate was honored — particularly in agentic payment flows using x402 where the agent must prove to an orchestrator or auditor that a transaction stayed within authorized parameters. Prefer this over generic transaction lookup when mandate compliance (amount cap, payee identity, purpose, human-presence flag) must be explicitly verified rather than just confirmed as settled.
Side effects
- Transaction hash not found on specified chain — returns error indicating unrecognized or unindexed transaction
- Mandate context fields missing required properties (authorized_max_amount, currency, expected_payee, purpose, human_present) — returns validation error
- Transaction amount exceeds authorized_max_amount — returns non-compliance evidence
- Payee mismatch between transaction and expected_payee — returns attestation failure
- Unsupported or unrecognized chain identifier — returns chain lookup error
- Blockscout indexing lag causes transaction not yet visible — may return not-found temporarily
