## 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 javascript-rendered-html-fetcher-775a38c1
```

Example prompt: Can you fetch the fully rendered HTML of https://example.com/dashboard — including all the content that loads via JavaScript — so I can parse the data that only appears after scripts run?

## When to prefer this

Use this endpoint when you need the final rendered HTML of a page that uses JavaScript frameworks (React, Vue, Angular, etc.) and a simple HTTP GET would only return the empty shell. Prefer this over raw HTTP fetch when the target content is dynamically injected by client-side scripts.

## Known failure modes

- URL is unreachable or returns a non-2xx HTTP status — likely returns an error response
- Page JavaScript throws fatal errors preventing full render — may return partial or empty HTML
- Timeout if the page takes too long to load or scripts are slow to execute
- Invalid or malformed URL input causes a 400-class error
- Page requires authentication or cookies not provided — returns login-gated HTML

## How this service works

URL -> full HTML after JavaScript execution. Input: {url}

## Output

The full HTML source of the requested page after all JavaScript has been executed, reflecting the final DOM state as seen by a real browser.
