## 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 x240-url-screenshot-api-15cb3df9 -d '<json body>'
```

Example prompt: Can you take a screenshot of https://example.com and give me the image so I can see what it looks like right now?

## When to prefer this

Choose this endpoint when you need a real browser-rendered visual capture of a web page (including JavaScript-heavy SPAs) rather than raw HTML. Prefer it over HTML scraping when the goal is visual verification, archiving appearance, or generating a thumbnail image. It complements text-scraping siblings by covering the visual layer.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error
- URL is malformed or missing the http/https scheme — returns validation error
- Target page takes too long to load — may timeout
- URL resolves to a private/internal IP address — likely blocked
- Page returns a non-200 status — screenshot may show error page or fail

## How this service works

Screenshot of any URL taken in a real browser, returned as a base64 PNG

## Output
