Website screenshot API — one POST, one PNG

Full-page or viewport capture of any public URL with device presets. The simple front door agents search for: no browser pool to run, no Puppeteer to maintain.

Quick start (curl)

Get a key first – no signup: curl -X POST https://api.bigapi.dev/v1/keys (100 free operations, 7 days).

curl -X POST https://api.bigapi.dev/v1/screenshot -H 'Authorization: Bearer $KEY' -H 'Content-Type: application/json' -d '{"url":"https://example.com","device":"mobile"}' -o shot.png

Give it to your agent (MCP)

Add BiGapi to Claude Desktop, Cursor or any MCP client – the server fetches its own key on first use:

{
  "mcpServers": {
    "bigapi": { "command": "npx", "args": ["-y", "@bigapi/mcp"] }
  }
}

Then simply ask: “Take a mobile screenshot of bigapi.dev and show it to me.” – the model calls the screenshot tool.

When your agent needs this

• Visual checks in agent workflows („does the page look right?“)
• Archiving a page state with a timestamp
• Feeding a vision model a rendered page

Parameters

Pricing

Every response carries X-BigAPI-Cost, X-BigAPI-Balance and X-BigAPI-Free-Ops – your agent can budget on its own.
