The x402-captcha-solve service is listed and selling: $0.10 per call for reCAPTCHA v2/v3, hCaptcha and Turnstile, at /x402/captcha-solve. There is no free trial, so a first request returns a standard x402 402 payment challenge — that is the normal answer, not an error.
An earlier version of this page said the service had been delisted because its upstream relay stopped working. That was wrong. The relay process was running the whole time — a firewall rule on the relay host was refusing the port — and it was fixed on 2026-09-16.
