POST /extract

This is a paid x402 endpoint. You're seeing this preview because you opened it in a browser with GET — no charge, nothing happened.

Price: $0.01 USDC per call
Network: eip155:8453
Asset: USDC · Scheme: exact
payTo: 0xea6c6d0361a758e51004fc5b0c31a3c6b2408858
Facilitator: https://api.cdp.coinbase.com/platform/v2/x402

To call it

curl -X POST https://x402-extract-wg5z.onrender.com/extract \
  -H 'Content-Type: application/json' \
  -H "PAYMENT-SIGNATURE: <base64-signed-payment>" \
  -d '{"url":"https://example.com/article","format":"markdown"}'

The first unpaid POST returns 402 with the full payment challenge (amount, asset, payTo, supported schemes). Sign it with any x402 v2 client and retry — the signed payment travels in the PAYMENT-SIGNATURE header.
