# Challenges

> Captchas and challenge pages an AI agent meets on real sites: which ones it solved, how many runs it took and where it failed.

Each article here takes one challenge an agent runs into, such as Cloudflare Turnstile, reCAPTCHA or hCaptcha, and reports what happened on a named site on a named date. A challenge counts as solved only when the site let the run continue, not when a widget turned green. Where a challenge refused correct answers, the article says so.

For what the agent's tools can do today, the [documentation](/docs) is the reference.
