Split or extract PDF pages via API

Page ranges like 1-3,7,9-z (z = last page) into a new PDF. Structural extraction, no quality loss.

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/pdf/split -H 'Authorization: Bearer $KEY' -F 'file=@in.pdf' -F 'pages=2-4' -o part.pdf

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: “Extract pages 2-4 from this PDF.” – the model calls the pdf_split tool.

When your agent needs this

• Pull the signature page out of a contract
• Split scans into per-document files
• Reduce a deck to the pages a model should read
