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 x402-web-unlocker-anti-bot-bypass-captcha-solver-be7e7627 -d '<json body>'
```

Example prompt: Fetch the full rendered HTML from https://www.example.com/protected-page — use JavaScript rendering, wait 3000 milliseconds for the page to load, route through a US proxy, and return both the HTML and a screenshot.

## When to prefer this

Choose this endpoint when you need to access web pages that block standard HTTP crawlers, use JavaScript to render content, or deploy CAPTCHAs and anti-bot measures. It is ideal for scraping dynamic single-page applications, e-commerce sites, or any URL that returns blocked/empty content to regular bots. Prefer this over standard HTTP fetch tools when you encounter 403 errors, bot detection, or empty JS-rendered pages.

## Known failure modes

- Target site still blocks access despite anti-bot bypass — success: false returned
- Invalid or unreachable URL returns an error response
- Unsupported country code for proxy routing causes failure
- Timeout if wait time is too long or page never loads
- Invalid output type enum value causes a 400 error
- CSS selector specified in wait_for never appears on page, causing timeout
