OCR.chat API

Күзәтү

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)

Аутентификация

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.

Документ белән сөйләшү

Башланган эш турында сораулар бирегез. Җаваплар бары тик чыгарылган текстка нигезләнә һәм чыганак битен күрсәтә. Кагыйдә буларак, бу өчен аккаунт иконкасы кирәк, чөнки сөйләшү функциясе аккаунт белән чикләнгән.

POST /api/v1/chat/<uuid>/, JSON body {"message": "your question"}.
