REST API

Integrate FileForge into your workflow with the REST API. All endpoints accept multipart form data.

Create a Job

POST /api/jobs

curl -X POST {{BASE_URL}}/api/jobs \
  -F "file=@document.pdf" \
  -F "job_type=ocr" \
  -F "mode=both" \
  -F "ocr_engine=tesseract"

Response

{
  "job_id": "a1b2c3d4-...",
  "access_token": "xyz789...",
  "status": "queued",
  "result_url": "/api/jobs/a1b2c3d4-.../result"
}

Important: Save the access_token from the response — you'll need it to check status and download results. Tokens are session-specific and cannot be recovered.

Check Job Status

GET /api/jobs/{job_id}?token={access_token}

curl "{{BASE_URL}}/api/jobs/a1b2c3d4-...?token=xyz789..."

Response

{
  "id": "a1b2c3d4-...",
  "status": "completed",
  "filename": "document.pdf",
  "progress": 100
}

Get Result

GET /api/jobs/{job_id}/result?token={access_token}

Returns the full result JSON when the job is complete, or 202 while still processing.

curl "{{BASE_URL}}/api/jobs/a1b2c3d4-.../result?token=xyz789..."

Download Output

GET /api/jobs/{job_id}/download/{format}?token={access_token}

Download the converted file. Format depends on job type:

curl -O "{{BASE_URL}}/api/jobs/a1b2c3d4-.../download/txt?token=xyz789..."

Job History & Sessions

FileForge uses session-based access control to protect your privacy:

Session-only access: Your job history is available only in your current browser session
Private by default: Each job has a unique access token — only you can view or download your results
No permanent storage: When you close your browser or clear cookies, you lose access to your job history
Download immediately: Download your files while your session is active — they won't be accessible later

Privacy: All uploaded files and results are automatically purged after 24 hours. Jobs are isolated per session — other users cannot access your files. No data is shared with third parties.
