OCR.chat API

Gambaran Umum

The OCR.chat API is a small REST interface. You POST a file and get back a job with the recognized text and a per-page breakdown (text, bounding boxes, confidence). Jobs of 5 pages or fewer return inline; larger jobs return immediately with a pending status that you poll until done.

• Base URL: https://ocr.chat
• Formats in: PNG, JPG, WEBP, GIF, BMP, TIFF, and multi-page PDF
• Formats out: txt, md, docx, pdf, csv, json
• Engines: cpu (fast, printed docs) and vlm (premium AI, handwriting, complex layout, math)

Autentikasi

Authenticate with your API token (find it on your account page) as a Bearer header:

Authorization: Bearer YOUR_API_TOKEN

You can also pass ?api_token=… as a query parameter. Usage is metered against your account's page balance.

Kirim dokumen

POST /api/v1/ocr/, multipart form upload.

  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -F "file=@invoice.pdf" \
  -F "tier=vlm" \
  -F "language=auto"

Returns the job. For ≤5-page files it is already done with the text; larger files come back pending/processing, poll the status endpoint.

Each page processed costs credits (1/page on the fast tier, more on premium). Paid plans raise per-file page caps and add priority. See pricing.
