How this service works
Agent payments on Arc, measured in the open. Every x402 settlement, read from the chain and classified by public, versioned rules.
Output
Returns a JSON array of payment records under a `data` key, each with payee, payer, phase, token (e.g. USDC), amount, transaction hash, direction (in/out), log index, submitter, block time, facilitator, x402_likely flag, block number, classification label, class version, and confidence score. Also includes `as_of` timestamp, `next_cursor` for pagination, `classification_run` ID, and `methodology_version`.
Example use cases
Audit agent wallet spending
“Show me all x402 payments made by or to wallet 0x9579e4804fa2216c8e4e49ffd3c495afc6f6971e — I want to know the amounts, which facilitator handled each one, and how they were classified.”
Monitor facilitator usage patterns
“Pull the x402 settlement history for address 0x6bf001bb5f5e75396d92163325ca01fdebe2e9a9 and tell me which facilitators like Arcus processed payments and what phase each payment was in.”
Verify test vs production payments
“For wallet 0xe074bf7f0aa27642059e6fcc40688b61d8265b49, fetch its classified payment history from Farelight so I can see which transactions were flagged as test payments versus real ones and what confidence scores they got.”
Technical details
Endpoint
GEThttps://farelight.xyz/api/v1/wallets/%7Baddress%7D/payments?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain x402 payment records for a specific wallet address with human-readable classification metadata (phase, facilitator, confidence). Prefer it over generic blockchain explorers when you need Arc/x402-specific classification by versioned public rules, or when you need structured, paginated output ready for agent consumption. Best when auditing agent spending, researching facilitator usage, or distinguishing test from production settlements.
Side effects
- Invalid or malformed wallet address returns an error or empty dataset
- Wallet with no x402 activity returns an empty data array
- Pagination cursor mismatch or stale cursor may return unexpected results
- Rate limiting or $0.01 USDC payment failure prevents access
- Blockchain indexing lag may cause recent transactions to not yet appear
