## 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 defi-intel-agent-gateway-viewport-screenshot-webp-079d6441 -d '<json body>'
```

Example prompt: Can you take a screenshot of https://app.uniswap.org and send it back to me as a WebP image so I can see what the current swap interface looks like?

## When to prefer this

Use this endpoint when you need a visual, human-readable snapshot of a publicly accessible webpage — particularly DeFi dashboards, DEX UIs, or token analytics pages — without setting up a browser automation stack or managing API keys. Prefer it over HTML/Markdown extraction endpoints when the visual layout or chart rendering matters, not just the text content. Not suitable for pages behind authentication walls or live video streams.

## Known failure modes

- Login-gated or authentication-required pages will fail or return a login screen instead of the intended content
- Streaming sites (e.g. video platforms) may not render correctly or may be blocked
- Invalid or unreachable URLs will result in an error or empty response
- Very JavaScript-heavy SPAs may render incompletely if hydration takes too long
- Incorrect query parameter format may result in a 400 error

## How this service works

Capture a URL's viewport as a WebP image (base64) at a chosen size. DO NOT use for login-gated pages or streaming sites. — $0.006 USDC/call on Base. Pay-per-call via x402 — no API key, no account. Free samples daily.

## Output

A base64-encoded WebP image representing the captured viewport of the requested URL. The response includes the raw image data that can be decoded and displayed or stored. The image reflects the page as rendered at the chosen viewport dimensions.
