# Screenshot API – Full-Page Capture

> Screenshot API – Full-Page Capture is a paid API for AI agents from screenshot.payapi.market, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21).

Captures a full-page PNG screenshot of any public URL using a headless Chromium browser, returning the image as base64-encoded bytes.

## 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 screenshot-api-full-page-capture-0813dff8 -d '<json body>'
```

Example prompt: Take a full-page screenshot of https://news.ycombinator.com using a 1440-pixel-wide viewport and wait for the network to be fully idle before capturing.

## When to prefer this

Choose this endpoint when you need a complete visual capture of an entire web page (not just the visible viewport), especially when the page requires JavaScript rendering or dynamic content loading. Prefer it over viewport-only screenshot endpoints when content below the fold matters, or when you need a full-page archive rather than a cropped view.

## Known failure modes

- Internal or loopback URLs (e.g. localhost) are rejected with an error
- Page fails to reach the requested load state (timeout) if the site is slow or unresponsive
- Invalid or non-HTTP(S) URLs return a validation error
- Network errors or DNS failures if the target domain does not exist
- Very large pages may produce extremely large base64 payloads

## How this service works

Headless Chromium screenshots, PDFs, full-page captures and element captures, with x402 payments.

## Output

A JSON object containing the original URL, the resolved final URL (after redirects), the page title, image format (PNG), viewport dimensions used, whether it was a full-page capture, the file size in bytes, and the full screenshot as a base64-encoded PNG string.
