Website screenshot API: capture any web page as an image

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Render any public web page in a real headless Chrome browser, with JavaScript executed, and get a JPEG screenshot (1280 px wide, base64) plus the final URL, HTTP status and page title. Set fullPage=true to capture up to 4000 px of page height. Use for visual checks, page previews, monitoring and feeding pages to vision models.

When to use it

Capture a page as a JPEG after its JavaScript has run
Make page previews or monitor how a page looks
Feed a page to a vision model

Inputs

Name	Type	Description
`url` (required)	string	Absolute http(s) URL of the page to capture
`fullPage`	string	Set to true to capture the full page height (max 4000 px) instead of the 1280x800 viewport

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/screenshot?url=https%3A%2F%2Fexample.com"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "url": "https://example.com/",
  "finalUrl": "https://example.com/",
  "status": 200,
  "title": "Example Domain",
  "width": 1280,
  "height": 800,
  "contentType": "image/jpeg",
  "imageBase64": "/9j/4AAQSkZJRgABAQAAAQABAAD..."
}

Questions

How large is the image?

1280 px wide; with fullPage=true up to 4000 px of page height, returned as base64 with the final URL, status and title.

How do I pay?

Each successful call costs $0.01; failed calls are not charged. This tool is not in the free calls; pay with card credits (from $1; the key goes in an Authorization header or, for clients that can only fetch a URL, as api_key= in the URL) or per call in USDC over x402 or MPP. No account is needed.
