Large Document Processing: For documents over 50 pages, we strongly recommend using the /extract_async endpoint instead. The async endpoint prevents timeout issues and provides better handling of extensive processing tasks.

​
Large Document Response Structure

For documents exceeding 70 pages, the API returns a URL structure instead of the direct response: 
{
  "is_url": true,
  "url": "https://pulse-studio-api.s3.region.amazonaws.com/results/...",
  "plan-info": {
    "pages_used": 0,
    "tier": "foundation"
  }
}

​
Key Points:

  • Documents over 70 pages return a URL containing the complete response
  • URLs automatically expire after 24 hours
  • No changes required to your API request structure
  • For documents under 70 pages, the API continues to return results directly

​
Implementation Tips:

  1. Check if response contains "is_url": true
  2. If true, fetch the complete document data from the provided URL
  3. Store URLs securely as they contain your processed results
