## 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-snap-browser-rendering-api-e347d637 -d '<json body>'
```

Example prompt: Take a full-page screenshot of https://example.com — render it in a real browser so JavaScript executes, wait 2000ms for dynamic content to load, and give me back a PNG.

## When to prefer this

Choose this endpoint when a plain HTTP fetch returns an empty or incomplete HTML shell because the page uses client-side JavaScript rendering (React, Vue, Angular, etc.), or when you specifically need a visual screenshot or PDF of a page rather than raw HTML. It is especially valuable for AI agents that need to see what a page actually looks like, archive a visual snapshot, or extract data from SPAs. Prefer it over static HTTP fetchers whenever JavaScript execution is required to see meaningful content.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — status field reflects the actual HTTP error code
- Timeout if the page takes too long to load or waitMs is set too high
- Invalid or non-public URL (e.g. localhost, private IP) rejected
- Unsupported format value causes a format error
- Page with heavy anti-bot protections (Cloudflare, CAPTCHAs) may not render correctly
- Payment not completed — x402 payment required before rendering begins

## How this service works

Pay-per-call browser rendering for AI agents. Render any URL in a real headless browser and get back a full-page screenshot (PNG), a PDF, or the JavaScript-rendered HTML — solves the empty-shell problem when plain HTTP fetches hit client-rendered pages.

## Output

Returns a JSON object containing: the output format identifier, the final URL after redirects, and either a base64-encoded PNG or PDF (in the `base64` field) or a JavaScript-rendered HTML string (in the `html` field), plus the HTTP status of the target page and its content type.
