## 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-4ab967cd
```

Example prompt: Can you take a screenshot of https://example.com at 1280x800 resolution and send me the image?

## When to prefer this

Use this endpoint when you need a visual render of a live webpage as a JPEG image, especially in automated agent workflows that require pay-per-call micro-payments via x402 (USDC). Ideal for one-off visual checks, audits, or page previews without setting up a full headless browser infrastructure. Prefer this over general web scraping tools when the output needed is a visual image rather than raw HTML or structured data.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — screenshot may fail or return an error
- Timeout if the target page loads slowly or has heavy JavaScript
- Private/localhost URLs rejected as input
- Viewport dimensions outside allowed range (width 320-1920, height 240-1920) cause validation error
- Payment failure via x402 protocol results in 402 response before any screenshot is taken

## How this service works

50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.

## Output

Returns a JSON object with a base64-encoded JPEG image string (data:image/jpeg;base64,...) and the image size in bytes. The image reflects the rendered visual state of the target URL at the specified viewport dimensions.
