# Create Upload URL

POST https://api.sarvam.ai/doc-ai/v1/job/upload
Content-Type: application/json

Creates a direct-upload handle for a file to be processed later.

**Flow:**
1. Call this endpoint with the MIME type you will upload (e.g. `application/pdf`).
2. Upload the file using the returned `method`, `url` and `headers` before `expires_at`.
3. Pass the returned `upload_id` through the `upload_ids` field on a later digitise or extract job request.

When `content_type` is set, the upload's `Content-Type` header must match it.
