AgentX402PayEvery route, priced in USDC, no subscription
There's no signup and no API key. Call any route below, get an HTTP 402 response with the exact price, sign a payment with an x402-compatible client, retry the request, and the data comes back. Payments settle on Base, Polygon, Arbitrum, or Solana — pick whichever chain you already hold USDC on (except the Text Generator and Heartbeat routes, which take Base only). Prices shown are per call unless noted otherwise; the live, machine-readable source of truth for every price is each route's own HTTP 402 response and /openapi.json.
