# CoinOpSelect Agent Data API

Pay-per-call agent data over x402 on base. No signup, no API key, no minimum spend. Every paid endpoint answers HTTP 402 with machine-readable payment terms; settle with USDC on Base and the data comes back. Free endpoints: GET /api/v1/health (liveness + a payment-readiness block: payable, network, payTo and cheapest call) and GET /api/v1/catalog (the catalog, with the x402 requirements for every paid route). Discovery documents: /openapi.json and /.well-known/x402. Settlement runs through the PayAI facilitator and the receiving address is published in the 402 challenge, never hardcoded here. Free sample endpoints let you preview paid routes without paying: /api/v1/vaults/apy-rates/sample, /api/v1/vaults/backstop/sample, /api/v1/vaults/health-factor/sample, /api/v1/query/token-safety/sample and /api/v1/query/wallet-risk/sample.
