## 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-dev-03b71e1d -d '<json body>'
```

Example prompt: Can you take a full-page screenshot of https://example.com and give me a PNG image with a 1280x800 viewport?

## When to prefer this

Use this endpoint when you need a visual image of a live or static webpage, including JavaScript-rendered content. Prefer this over HTML scrapers when the goal is visual verification, thumbnail generation, or capturing styled page layouts. Also useful for archiving visual snapshots of pages or rendering custom HTML to image.

## Known failure modes

- URL is unreachable or returns a non-200 status — screenshot may fail or return blank
- Invalid CSS selector causes element capture to fail
- Timeout if the page takes too long to load JavaScript
- Malformed HTML input causes rendering errors
- Unsupported image format requested
- Payment not accepted or insufficient USDC balance
