Solve hCaptcha in your stack.

Practical, copy-pasteable guides for getting a real hCaptcha token back into your pipeline. Read the sitekey, call the API, inject the token, then continue.

• Python hCaptcha solver: pip install nonecap, with sync, asyncio, and plain-requests examples.
• Solve hCaptcha in Selenium: the Python flow, token injection included.
• hCaptcha solving for web scraping: the full pipeline with a Python example.
• Solve hCaptcha in Playwright: Python & Node, with token injection included.
• Solve hCaptcha in Puppeteer: the Node.js flow, token injection included.
• hCaptcha solving for AI agents: call the solver as a tool inside an agent loop.

Every guide follows the same four steps

• Read the sitekey from the page (each guide shows the one-liner for its framework; the sitekey explainer covers the manual ways).
• Request a token with POST /v1/solves, passing the sitekey and page URL. Block with ?wait=N or poll.
• Inject the token into the form's hidden h-captcha-response field and fire the widget callback if the site uses one.
• Submit and move on. Tokens are single-use and expire in about two minutes, so guides mint them right before submission.

Picking a starting point

If you drive a browser, go straight to the Selenium, Playwright, or Puppeteer guide for your stack. If you make plain HTTP requests, the web scraping guide covers detecting the widget and submitting the token without a browser at all. The Python guide is the shortest path if you just want pip install nonecap and a working call, and the AI agents guide wraps the same flow in a tool schema your agent can call on demand.

Every guide targets hCaptcha (regular, invisible, and enterprise rqdata). For the full endpoint and object reference, see the API reference; for what a token actually is and why injection works, the hCaptcha explainers cover the mechanics.
