## 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 stableflare-browser-crawl-cloudflare-browser-rendering-16aab94c -d '<json body>'
```

Example prompt: Take a full-page screenshot of https://example.com using a 1280x800 viewport and give me the result as a PNG.

## When to prefer this

Choose this endpoint when you need a pay-per-request, no-subscription headless browser screenshot or page render backed by Cloudflare infrastructure, especially useful for one-off captures without committing to a SaaS plan. Ideal for agents that need to visually verify pages, capture dynamic JavaScript-rendered content, or screenshot specific DOM elements.

## Known failure modes

- URL is unreachable or returns a non-200 status — browser timeout or navigation error
- CSS selector not found — waitForSelector times out
- Invalid URL format — schema validation error
- Authentication credentials incorrect — page may not render as expected
- Timeout exceeded during page load — gotoOptions.timeout reached
- Payment not accepted — x402 payment flow fails or USDC balance insufficient
