Ready-to-paste prompt
Read https://captcha-solver.com/llms.txt and write a Python function solve_recaptcha(website_url, website_key) that solves reCAPTCHA v2 through this API. Take the API key from the CAPTCHA_API_KEY environment variable.
01
Use an LLM
Share the llms.txt link with your AI assistant, or send it the ready-made prompt above and describe what you need in plain language.
02
Debug and tune with the LLM
Ask the AI to test the integration on your page: pick the right captcha parameters, sort out errors, and fix the code.
03
Get a working integration
The AI writes integration code for your stack: Python, Node.js, PHP, Go, and more.
How it works
From sign-up to first solve in 2 minutes
01
Sign up
Email and password, no phone verification, no company data. Once you confirm your email, your API key is available in the dashboard.
02
Top up balance
Any convenient method, any amount. Funds never expire and aren't tied to a billing cycle.
03
Send requests
One POST request with an image or site-key. Returns the solution. Charged only on success.
A captcha solver is a service that solves captchas for your automation. A script cannot pass a captcha on its own: when it runs into one, for example in E2E tests, it simply gets stuck. Instead, your code sends the captcha to our API and gets the solution back: a token, recognized text, or click coordinates, depending on the captcha type. You then apply that solution on the target page the same way a human answer would be applied: pass the token to the widget or form, type the text into the field, or click the points. See the docs for how it works step by step.
The API is plain REST: one POST request and a JSON response, no complex auth. Official SDKs are available: Python on PyPI, Node.js on npm, source for both on GitHub. For any other stack, any AI assistant can write integration code for you in seconds using our .
FunCaptcha, VK Captcha, and Temu Captcha are next on the roadmap; see the pricing page for the current status. New captchas are added as new task types without changing the API format, so existing integrations keep working.
It's easier than it looks: you don't have to write the code yourself. Send any AI assistant (ChatGPT, Claude, etc.) a link to our and ask it to build the integration for your case. The AI will write working code and guide you through the next steps.
You can top up your balance with cryptocurrency right from your dashboard, on the "Top Up Balance" page: enter an amount in USD and pay with BTC, ETH, USDT, USDC or TRX — your balance is credited automatically once the payment is confirmed. Bank card payments are coming next. Need a different payment method? Email us at support@captcha-solver.com.
You only pay for solved captchas, i.e. solutions where a token was returned in the response. If no token came back, you are not charged and a retry is free.
This is normal: the way a token is applied on the target page can be unique and site-specific, and such cases need to be debugged individually. Start by checking how the target page applies the token and what happens to it when you solve the captcha on the page manually. Keep in mind that a captcha may use extra protection parameters, and they can be dynamic rather than static. If the captcha has such parameters, make sure you fetch them correctly every time. If you can't pinpoint the cause, contact our support team and they will help you.
Token reports are not implemented yet; the feature will be added later. If your solutions don't work, contact our support team.
No, sign up as an individual: email, password, and you can top up and send requests right away.
The service is intended for lawful automation only: testing your own applications or systems you are authorized to test, accessibility scenarios, and automation permitted by the target resource's rules. Bypassing third-party protection without authorization, spam, and fraud are prohibited — see the Acceptable Use Policy for details.
