screenshot · REST + MCP

Capture a screenshot of a web page

Take a screenshot of a website. Open any web page URL in a real browser and capture it as a PNG image, either the visible area or the full page. Use it to see what a site looks like, check a page layout, or capture visual proof of a web page.

$0.01 USD per successful paid call

This tool uses prepaid credit. Connect without a key and your agent will get a key and payment link when it needs this tool.

Charged once per call that returns a result, including an empty result list. Failed calls are free.

Connect your agent

Use it in your chat

Start with no key

In Claude.ai, Claude Desktop, Claude Code, ChatGPT or Codex, add a custom connector with this URL. No API key or Authorization header is needed.

Try a few free calls a day with read_page, domain_check, domain_info, pdf_to_text, vulnerability_lookup, or paper_search. Each free result says how many are left and when they reset (midnight UTC).

A paid tool called without a key returns a new API key and a payment link instead of a result, and nothing is charged. In Claude, a Connect button opens the same payment page. Once credit is added, the agent can continue in the same chat with that key.

Already have a key?

If your connector cannot send headers, use this URL instead. Replace YOUR_API_KEY with your key.

https://unstuckapi.com/mcp?key=YOUR_API_KEY

Keep the completed URL private: it contains your API key.

Ask your agent to call screenshot with these arguments:

{
  "url": "https://example.com",
  "full_page": true
}

Replace YOUR_API_KEY with your key. The following command makes a paid call if it succeeds.

export UNSTUCK_API_KEY="YOUR_API_KEY"

curl 'https://unstuckapi.com/v1/tools/screenshot' \
  -H "Authorization: Bearer $UNSTUCK_API_KEY" \
  -H 'Content-Type: application/json' \
  --data '{"url":"https://example.com","full_page":true}'

The response contains result, charged_usd, and your remaining balance_usd. Invalid input and failed tool calls are not charged.

Developer option: MCP with a header

For clients that support headers, connect using Streamable HTTP and these values:

https://unstuckapi.com/mcp

Authorization: Bearer YOUR_API_KEY
