## 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 agent402-tools-web-renderer-5738c4c7 -d '<json body>'
```

Example prompt: Can you grab the full content of https://example-spa.com/dashboard and give it to me as clean readable text? It's a React app so normal fetching won't work.

## When to prefer this

Use this endpoint when a plain HTTP GET to a URL returns an empty shell or minimal content because the site is a single-page application (SPA) or relies heavily on JavaScript for rendering. Prefer it over plain fetch-based scrapers when the target uses React, Angular, Vue, Next.js, or similar frameworks.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — page cannot be rendered
- URL points to a non-HTTP resource or a local/private IP — rejected as invalid input
- Page requires authentication or login to display content — returns empty or login-wall markdown
- Page takes too long to render (timeout) — partial or empty result returned
- Malformed or missing URL parameter — validation error returned

## How this service works

Render a page in a real headless Chromium browser (JavaScript executed) and return its main content as clean markdown. Use it for single-page apps and JS-heavy sites where a plain fetch returns an empty shell.

## Output

Clean markdown representation of the main content of the rendered page, extracted after full JavaScript execution in a headless Chromium browser.
