GET /api/v1/x402/preflight/url-check

live

Cheap robots.txt preflight before you call the Minifetch /extract and /run/seo-page-audit endpoints: returns whether the Minifetch user agent may fetch a target URL (allow/deny) plus its crawl-delay. If blocked or setting a crawl delay read https://minifetch.com/tutorials/unblock-minifetch . Checks the URL as given — does not follow redirects. Supports GET & POST

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

The catalog declares GET. 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.
