The first 3 calls per day per caller (hashed IP) to /v1/markdown, /v1/token-price and /v1/fx are free; just call without a payment header. A global daily cap applies. The X-Free-Trial-Remaining response header shows what is left. Crawl and alert passes are never free.
Call an endpoint. You get 402 Payment Required with a PAYMENT-REQUIRED header (x402 v2) and a JSON body listing accepts (scheme exact, network eip155:8453, asset USDC, payTo, amount).
Sign the USDC authorization with your wallet and retry with the PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1) header.
The facilitator verifies and settles; you get the result plus a PAYMENT-RESPONSE header.
// any x402 client works, e.g. @x402/fetch:
import { wrapFetchWithPayment } from "@x402/fetch";
const fetchWithPay = wrapFetchWithPayment(fetch, yourX402Client);
