# Split a PDF by page ranges

## Request

- Base URL: `https://api.cofferdock.com`
- URL: `https://api.cofferdock.com/pdf-split`
- Auth: API key in header `x-api-key`

Creates one PDF per range. Ranges use 1-indexed pages: "1-3,5,7-9" gives three files. For one file per page, list every page: "1,2,3". One credit regardless of how many files come out.

Costs 1 credit per call.

## Request body

- object
  - `file` string, byte, required: The PDF, base64-encoded.
  - `ranges` string, required: Required. e.g. "1-3,5,7-9" (one output file per comma-separated group).
  - `output` 'json' | 'binary' | 'url': How to return the PDFs: "json" (base64 in the JSON response), "binary" (the PDFs itself, ready for n8n/Make/Zapier) or "url" (a temporary download link, valid 15 minutes). Default: json when the request is JSON, binary when the input was sent raw.

## Response `200`
