## 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 web-screenshot-capture-x402-13f0727b -d '<json body>'
```

Example prompt: Can you take a screenshot of https://example.com at a 1280x900 viewport and give me the PNG image?

## When to prefer this

Choose this endpoint when you need a full browser-rendered (JavaScript-executed) screenshot of a web page returned as a base64 PNG, billed per-call with no subscription required. It is ideal for agents that need occasional visual captures of dynamic or JS-heavy pages and want micropayment-based access via USDC on Base rather than managing a headless browser themselves.

## Known failure modes

- URL is unreachable or returns a non-200 response — error field set, no image returned
- JavaScript rendering timeout for slow or complex pages
- Invalid URL format causes request rejection
- Viewport dimensions outside supported range may cause unexpected crops or errors
- Payment failure via x402 prevents the call from completing

## How this service works

Paid per-call web tools for AI agents: DNS, TLS, robots.txt, hashing, JavaScript rendering and screenshots. Payment over x402 (USDC on Base).

## Output

Returns a JSON object containing the page URL, image dimensions (width and height in pixels), file size in bytes, and the full PNG screenshot encoded as a base64 string. On failure, an error field is populated instead of the image data.
