Captures a full-browser screenshot of any public webpage as a base64-encoded PNG or JPEG, rendered in headless Chromium, with configurable viewport, full-page capture, and settle delay

## 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 x402-gateway-page-screenshot-f84c6554 -d '<json body>'
```

Example prompt: Take a full-page PNG screenshot of https://news.ycombinator.com at 1280x720 viewport with a 1000ms settle delay so the page has time to load.

## When to prefer this

Choose this endpoint when you need a real rendered browser screenshot of any public webpage — including JavaScript-heavy SPAs, dynamic content, or pages requiring a settle delay — and want to pay per call with no API key or subscription. Prefer it over HTML-scraping or static fetch approaches when visual fidelity matters. The configurable viewport, full-page mode, y_offset slicing, and retina scaling make it suitable for visual QA, archiving, monitoring UI changes, or extracting visual content from tall documents.

## Known failure modes

- 413 returned if full_page is true and the document exceeds 10,000px tall (use y_offset slicing instead)
- Non-zero y_offset rejected in stealth mode (Chromium-only parameter)
- Timeout or render error if the target URL is unreachable or returns a non-200 status
- Payment failure if USDC balance on Base is insufficient for the $0.002 per-call fee
- Invalid URL scheme (non-http/https) causes a validation error
- Width outside 320-1920 or height outside 240-1080 rejected
- delay_ms outside 0-5000 range rejected
- device_scale_factor outside 1-2 range rejected

## How this service works

Page Screenshot: Full-browser screenshot of any public page as base64 PNG or JPEG: viewport or full-page, custom size, rendered in headless Chromium. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/page_screenshot.

## Output

Returns a base64-encoded image (PNG or JPEG) representing the rendered webpage. The image reflects the configured viewport size, device scale factor, and settle delay, and can be full-page (up to 10,000px tall) or a windowed slice starting at y_offset.
