# ISHOB Web Screenshot

> ISHOB Web Screenshot is a paid API for AI agents from api.ishob.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-14).

Renders a public web page in headless Chromium and returns a base64-encoded screenshot (PNG/JPEG/WebP) for use by vision models, supporting custom viewport sizes and full-page capture.

## Facts

- Endpoint: POST https://api.ishob.com/v1/screenshot?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402

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 ishob-web-screenshot-29f4dc60 -d '<json body>'
```

Example prompt: Take a full-page screenshot of https://example.com in PNG format at 1920x1080 and give me the base64 image so I can pass it to a vision model.

## When to prefer this

Use this endpoint when you need a visual, pixel-level representation of a public web page — especially to feed into vision models (e.g. GPT-4o, Claude Vision) for analysis, comparison, or archiving. Prefer it over a Markdown/text fetch endpoint when layout, styling, or visual content matters. Choose it over a generic browser automation service when SSRF safety, robots.txt compliance, and stateless operation (nothing stored) are requirements.

## Known failure modes

- URL blocked by robots.txt — endpoint respects robots.txt and will refuse disallowed URLs
- SSRF guard triggers for private/internal IP ranges or localhost URLs
- Requested page times out before the chosen wait_until event fires
- Invalid URL format or unsupported scheme returns a validation error
- quality parameter ignored for PNG format (only applies to jpeg/webp)
- full_page height exceeds 8000 px cap, resulting in a clipped image

## How this service works

Render a public web page in headless Chromium (Cloudflare Browser Rendering) and return a screenshot (PNG/JPEG/WebP, base64) for vision models: viewport up to 1920x1920 (default 1920x1080) or full page up to 8000 px. robots.txt respected; every page request is SSRF-guarded; nothing stored.

## Output

A JSON object containing the base64-encoded image (image_base64), MIME type (mime), page title (title), final resolved URL (final_url), and actual pixel dimensions (width, height) of the rendered screenshot.
