x402 settlement is live on eip155:8453: sign a USDC transfer and retry with PAYMENT-SIGNATURE.

When to call it

Cheapest endpoint that answers the question, first.

Call it when the sentence above is the whole job. Its neighbours solve the same URL with a different trade-off — a browser instead of plain HTTP, a site instead of one page, one section instead of a document. /choose walks the decision in thirteen routes, cheapest first, browser last.

Not sure the page is worth paying for at all? /v1/probe is free and returns the status, content type, size, title, language and whether a bot wall is waiting — no body.

Request fields

JSON body. Send this to https://readfetch.com/v1/crawl.

Limits

Requests are JSON, 1 MiB maximum. Redirects are re-validated at every hop and capped at 5; the final URL is reported. is the whole-call budget — DNS, connect, redirects, retries and any render share it, and no step starts a fresh clock.

Failures come back as {"error": "…", "hint": "…"} with a status to branch on: 402 for the quote, 429 with Retry-After, 502 and 504 for the upstream. /docs lists the shapes.

Billing

Settled after the work, only when something was delivered.

$0.003 per delivered page. A response with billed: false settles nothing and names the next call to try.

billed: false means nothing settled: a bot wall, an empty extraction, an unsupported type or a transport failure. The hint on that response names the next call to try.

Every settlement carries a signed RECEIPT bound to the transaction. If a paid call delivered nothing, a claim issues a single-use credit for it — the rail cannot refund.
