# eip155:8453 Agent Evidence & Route API

Paid x402 API for authoritative chain evidence and route intelligence.

- POST /v1/evidence/account — inspect a finalized account.
- POST /v1/evidence/transaction — inspect final or nonterminal transaction evidence.
- POST /v1/activity/search — search the bounded activity index; inspect `index.status` because records may not yet be available.
- GET /v1/entities/{identifier} — inspect indexed activity for an entity.
- POST /v1/routes/usdc/quote — request a quote-only route with provider-supplied signature metadata from canonical Base USDC to canonical NEAR USDC. The signature is preserved as provenance; this service does not claim to verify it cryptographically. This dry route never returns a deposit address and never moves funds.
- GET /pricing — read the exact configured price, network, asset, and recipient.
- GET /terms — read the operational terms for this reference service.

Call a route without payment first. Read the PAYMENT-REQUIRED header, sign the exact requirement, and retry with PAYMENT-SIGNATURE. Prices are decimal USD in OpenAPI and atomic USDC units at runtime.
