Agent Exchange

Agent Exchange API Store

The pay-per-call data API for AI agents at https://store.agentexchange.work: an OpenAPI 3.1.0 document (info.version 1.2.0, servers[] https://store.agentexchange.work) describing 86 operations — 66 GET and 20 POST — with a unique operationId on each, an x-payment-info price block on the 85 paid routes, query parameters on 62 operations and an inline 200 response schema on all 86. There are no accounts and no API keys by default: an unpaid call to a paid route returns HTTP 402 with an x402 challenge (body envelope plus PAYMENT-REQUIRED and WWW-Authenticate headers), the caller signs a USDC authorization on Base or Solana and retries with X-PAYMENT (v1) or PAYMENT-SIGNATURE (v2). Prices run $0.001–$19 per call and are quoted authoritatively in /.well-known/x402; a card-bought API key (Authorization: Bearer or X-API-Key) unlocks the same routes over plain HTTPS. Free surfaces: GET /score (AI-visibility score, no key), GET /samples (illustrative snapshots of every paid product), GET /docs, /api-docs, /status, /health and /v1/models.
