How this service works
Deterministic Base transaction evidence for agents and audit trails.
Output
Returns a per-transaction array with each hash and a boolean 'matched' flag, plus a summary object with counts of submitted, matched, and mismatched transactions. No on-chain state is modified — the response is a deterministic evidence report suitable for audit logs.
Example use cases
Automated payment audit trail
“I need to confirm that these three Base transaction hashes all paid the correct recipient wallet 0x1234abcd...5678 — can you run them through the reconciliation service and give me a summary of which ones matched?”
Agent x402 payment verification
“My agent just made an x402 micropayment with hash 0xa1b2c3...d4e5 — please verify it was received by the right address and flag any mismatch so I can log the evidence.”
Batch payment reconciliation for invoices
“I have 10 transaction hashes from today's Base payments and I need to check each one matched its expected USDC recipient address — can you run them through the evidence brief and tell me how many passed?”
Technical details
Endpoint
POSThttps://transaction-evidence-brief-2026.bowu365.chatgpt.site/api/v1/reconcile/paidWhen to prefer
Use this endpoint when you need a deterministic, auditable record confirming that one or more Base blockchain transactions actually paid the correct recipient address, asset, and amount — especially for x402 micropayment trails, agent audit logs, or automated reconciliation of crypto invoices. Prefer it over generic block explorers when you need a structured pass/fail summary suitable for downstream automation or compliance records.
Side effects
- Invalid transaction hash format (must be 0x followed by 64 hex chars) returns validation error
- Transaction not yet finalized on Base returns unmatched or pending result
- Wrong expected recipient address causes matched:false for that entry
- Unsupported asset address format causes schema rejection
- Submitting more than 25 transactions in one request returns a validation error
- Network or RPC unavailability may return a 5xx error
