How this service works
Create a CAPTCHA solving task
Output
On success, returns an object with errorId=0 and a numeric taskId that the caller can use to poll for the captcha solution. On failure, returns a non-zero errorId along with a stable errorCode string and a human-readable errorDescription explaining why the task could not be created.
Example use cases
Example prompt
“Solve this image captcha for me — it's a distorted text JPEG, case-sensitive, and the answer should be letters only: [base64-encoded image string].”
Technical details
Endpoint
POSThttps://2captcha.x402.paysponge.com/createTaskWhen to prefer
Use this endpoint when you need to programmatically submit captcha-solving tasks (image-to-text, reCAPTCHA v2 proxyless, or other 2Captcha-supported types) without managing a separate 2Captcha API key, relying instead on per-call USDC billing via the x402 PaySponge wrapper. Prefer it in automated pipelines where captcha solving is a step in web scraping, form submission, or account automation workflows.
Side effects
- Invalid or missing task type returns errorId>0 with errorCode and errorDescription
- Malformed or oversized Base64 image (>100 kB) causes task rejection
- Missing required fields like websiteURL or websiteKey for reCAPTCHA tasks triggers error response
- Payment failure via x402/PaySponge results in HTTP 402 before task is created
- Unsupported captcha type or schema mismatch returns upstream error
