## 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 api-strale-io-a96d3f19
```

Example prompt: Can you take a full-page screenshot of https://www.example.com and give me the image? Make sure you wait for all the lazy-loaded content to appear before capturing.

## When to prefer this

Choose this endpoint when you need a visual rendering of a webpage as a PNG image, especially for SPAs, pages with cookie banners, or lazy-loaded content that simpler screenshot tools fail to handle correctly. Ideal when you need full-page captures rather than just above-the-fold content.

## Known failure modes

- URL is unreachable or returns a non-200 status — screenshot may be blank or an error page
- CSS selector specified in wait_for never appears — timeout error
- URL points to a non-HTML resource (PDF, binary) — may return unexpected output
- SPA fails to hydrate within timeout — partial or blank screenshot
- Invalid URL format — request fails with validation error

## How this service works

Take a full-page or viewport screenshot of any URL. Handles cookie banners, lazy loading, SPAs. Returns base64 PNG.

## Output

A base64-encoded PNG image of the rendered webpage, either full-page or viewport-only, after handling cookie banners and waiting for dynamic content to load.
