Quick start

Use an x402-compatible client against the endpoint that fits your question. A plain request is safe and returns the exact payment terms without charging anything:

curl -i https://proofwork-the402-webhook.phase-voice.workers.dev/v1/crypto-task-scan

After payment, repeat the request with the client-generated Payment-Signature header. Inputs are limited to public data; do not send keys or personal data.

Find this service

Unpaid calls return HTTP 402 with the payment terms. No account or subscription is required.
