# 2Captcha CreateTask via PaySponge

> 2Captcha CreateTask via PaySponge is a paid API for AI agents from 2captcha.x402.paysponge.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Submits a new captcha recognition task (image-to-text, reCAPTCHA v2, or other supported types) to 2Captcha via the PaySponge x402 billing wrapper, returning a taskId for polling.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 2captcha-createtask-via-paysponge-d27c3006 -d '<json body>'
```

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].

## When to prefer this

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.

## Known failure modes

- 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

## 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.
