POST /doc/extract

live

Structured data from any document for AI agents, $0.25 per call: send a PDF, DOCX, XLSX, HTML, image or plain text plus a JSON Schema, get back one JSON object filled from the document — invoices, contracts, forms, CVs, receipts. Fields the document does not state come back null. One call, url or base64 (max 10 MB). Unreadable input means a 400 and you pay nothing. USDC on Base, no account.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://agentdata-api.sander-van-aard.workers.dev/doc/extract' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
