Price: $1.00 / 1k solves · Speed: 1–3s

GeeTest v4 uses behavioral analysis and may present slide, icon, or gobang (AI) challenges.

Finding the captcha ID

Look in the page source or network requests for the GeeTest initialization:

initGeetest4({ captchaId: 'e392e1d7fd421dc63502672ef5e807ec', ... })

Or in a network request to gcaptcha4.geetest.com — the captcha_id query parameter.

Finding the risk type

The risk_type controls which challenge type to solve. Check the initGeetest4 call:

initGeetest4({ captchaId: '...', product: 'bind', riskType: 'slide' })

Valid values: slide (default), icon, ai.
