# Check a PDF before working on it

`POST /v1/check/pdf`

Reports the page count, whether the PDF has a text layer (false for scanned or blank PDFs), whether it is password protected, its size and its title and author. A password protected PDF is a normal answer with is_encrypted true, so a flow can branch. Something that is not a PDF is refused.

## Request body

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| content_base64 | string | yes | The PDF as base64. File content in a flow is already base64: send it as it is |

## Example request

A request body that works, as JSON.
