To call a paid endpoint: (1) send your request to its URL; (2) you will receive an HTTP 402 response with payment details in the body and headers; (3) pay the quoted USDC amount with an x402 client (e.g. @x402/fetch or @x402/evm on Base) and retry the same request. No API key or account is required — the payment is the authentication. Inspect a free, canned sample of every endpoint's output at GET /preview (no payment).
