# AGISHub Page Snapshot (HTML + Screenshot + Markdown + Accessibility Tree)

> AGISHub Page Snapshot (HTML + Screenshot + Markdown + Accessibility Tree) is a paid API for AI agents from api.agishub.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-16).

Captures multiple representations of a web page in a single call — rendered HTML, PNG screenshot, Markdown, and/or accessibility tree — using a headless browser.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agishub-page-snapshot-html-screenshot-markdown-accessibility-tree-78254edc
```

Example prompt: Take a full snapshot of https://example.com — I need the rendered HTML, a PNG screenshot, and the Markdown version, using a 1440px wide viewport and capturing the full scrollable page.

## When to prefer this

Use this endpoint when an agent needs both the visual representation and structured content of a page in a single call, avoiding multiple round-trips. Especially useful when you need rendered (JavaScript-executed) HTML rather than raw source, or when you need the accessibility tree for structured understanding. Prefer over generic scraping endpoints when you want a PNG screenshot alongside content, or when Markdown output is needed for downstream LLM processing.

## Known failure modes

- URL is unreachable or returns a non-2xx status — headless browser may return empty or error body
- Page uses heavy JavaScript that times out before rendering completes
- Invalid or malformed URL causes a 400 bad request
- Requested format not supported returns validation error
- Full-page screenshot of very long pages may time out or produce oversized output
- Anti-bot protections (CAPTCHA, bot detection) on the target page may block rendering

## How this service works

Capture several representations of a page in one call — rendered HTML plus a PNG screenshot by default, and optionally Markdown and the accessibility tree. Backed by a headless browser. Saves round-trips when an agent needs both the content and a visual of a page.

## Output

A JSON object containing one or more of: rendered HTML string, base64-encoded PNG screenshot, Markdown text of the page, and/or the accessibility tree — whichever formats were requested. Returned in a single response, saving multiple round-trips.
