POST /api/v1/x402/fetch

unprobed

Fetch any public web page as readable text — a browser-grade fingerprint, boilerplate stripped, links kept — or just its links or its SEO metadata. Plain HTTP (JS-rendered and bot-walled pages are reported as such; a browser-driven read is a run). $0.02 per call, no account.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

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.
