# CaptchaFox

Solve the CaptchaFox slide challenge and get a response token.

Solves the CaptchaFox challenge for a page protected by a CaptchaFox site key and returns a response `token`. The token is submitted to the site's own backend, which validates it with CaptchaFox (siteverify).

### What you get back

The response carries the `token` under `result`. Tokens are single-use and short-lived, and must be submitted to the site that owns the `site_key`.

### Proxy

A **sticky proxy is required** on every solve, like all Apex providers: the solver always runs through your proxy. CaptchaFox tokens are not tied to an IP, but the proxy rule applies anyway.

## Solve the CaptchaFox challenge

> Fetches the challenge configuration for the site key, replays a\
> real-Chrome attestation, solves the proof-of-work and the slide\
> challenge, and returns a response token.<br>
