​
Overview

Returns a pre-signed S3 PUT URL so you can upload files directly to S3. This bypasses API Gateway’s 10MB limit and allows uploads up to 5GB.
Use this endpoint for large files (up to 5GB). The pre-signed URL flow avoids API Gateway size limits.

​
How It Works

1

Step 1: Get Pre-signed URL

Call this endpoint with your desired file_name to get the upload URL
2

Step 2: Upload File to S3

Use the upload_url with a PUT request, setting the Content-Type header to the content_type value from the response
3

Step 3: Automatic Processing

After upload, the file is automatically processed through the document pipeline
The pre-signed URL expires in 15 minutes. Upload your file before it expires.
