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
A JSON object containing an array of daily records, each with date, USDC volume, payment count, facilitator name, unique payees, unique payers, and classification label. Also includes the as_of timestamp, query parameters echoed back, the current classification run number, and the methodology version used to classify agent payments.
Example use cases
Monitoring daily Arc agent payment volume
“Show me the daily breakdown of x402 agent payment volume on Arc for the past week, grouped by facilitator — I want to see how much USDC is moving through Circle vs Arcus.”
Tracking unique participant growth
“Pull the Farelight daily index for the last 30 days and tell me how the number of unique payers and payees in the agent classification has changed over time.”
Validating methodology version for compliance report
“What methodology version and classification run number does Farelight use for today's agent payment data? I need that for a compliance report on x402 settlement activity.”
Technical details
Endpoint
GEThttps://farelight.xyz/api/v1/index/daily?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need standardized, publicly versioned, on-chain-sourced daily aggregates of x402 agent payment activity on Arc — especially when you need facilitator-level breakdowns, reproducible methodology versioning, or trend data over a date range. Prefer it over raw blockchain queries when you want pre-classified 'agent' payment data with auditable methodology rather than raw transaction logs.
Side effects
- Invalid or out-of-range date parameters return an empty data array or error
- Unsupported token or classification values may return no results
- Service may return stale data if chain indexing is delayed
- Rate limiting or payment failure (x402 $0.005 USDC per call) results in 402 response
- Unknown phase values may produce unexpected filtering behavior
