Asynchronous Job Model

Creating a presentation is asynchronous:

1. Submit a create request → receive a task_id
2. Poll the task status until it’s completed (or failed).
   • Status values: processing, completed, failed.
   • On success, a presentation_id is provided.
3. Fetch the presentation using presentation_id to obtain a time-limited download URL and related metadata such as slide_countand elapsed_time .

Errors

All error responses share a common envelope:

{
  "error": {
    "type": "invalid_request_error",
    "code": "400",
    "message": "attachments must be a PDF or PPTX"
  },
  "request_id": "req_01J9K3G4"
}

Common error.type and error.code values:

• invalid_request_error - HTTP 400 - The request was malformed or contains invalid parameters
• authentication_error - HTTP 401 - Missing or invalid API key
• authorization_error - HTTP 403 - Valid API key but insufficient permissions
