DocToTable for Developers & AI Agents

The conversion API

POST /api/table converts an uploaded PDF into CSV. Upload the PDF first through the web converter to obtain a storageId, then request the conversion:

curl -X POST https://doctotable.com/api/table \
  -H "Content-Type: application/json" \
  -d '{"storageId": "<your-storage-id>"}'

The response is CSV; the first line is the header row. Repeat conversions of the same document are served from cache (X-Cache: HIT).

Authentication & limits

• Anonymous (free tier): the first 3 pages of a document are converted, limited to 5 conversions per day. No key or account required.
• Authenticated: pass a Firebase ID token as Authorization: Bearer <token> to convert full documents.
• Document limits: up to 10 MB and 30 pages per PDF.
• Rate-limit headers: responses include X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset; a 429 carries Retry-After. Please back off instead of retrying.
