OCR.chat API

Isicelo se-HTTP esisodwa sishintsha isithombe noma i-PDF ibe ngumbhalo ocacile, i-Markdown, amathebulethi, ne-JSON — ngezinhlobo ezingaphezu kuka-100. Ikhasi ngalinye lilinganiselwa, akukho okuthakazelisayo.

Umbono

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)

Ukuqinisekisa

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.

Faka idokhumende

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

curl -X POST https://ocr.chat/api/v1/ocr/ \
  -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.

{
  "uuid": "9f2c1b7e4a...",
  "status": "done",
  "tier": "vlm",
  "language": "auto",
  "page_count": 1,
  "mean_confidence": 0.98,
  "text": "INVOICE\nAcme Corp\nTotal: 215.00 USD",
  "markdown": "# INVOICE\n\n**Acme Corp** ...",
  "pages": [ { "index": 0, "text": "...", "blocks": [ { "text": "...", "bbox": [x0,y0,x1,y1], "confidence": 0.98 } ] } ]
}

Thola imiphumela

GET /api/v1/ocr/<uuid>/, poll until status is done or failed.

curl https://ocr.chat/api/v1/ocr/9f2c1b7e4a.../ \
  -H "Authorization: Bearer YOUR_API_TOKEN"

Layisha phezulu ifomu

GET /api/v1/ocr/<uuid>/download/?format=md, export the result. format is one of txt, md, docx, pdf, csv, json.

curl -L "https://ocr.chat/api/v1/ocr/9f2c1b7e4a.../download/?format=docx" \
  -H "Authorization: Bearer YOUR_API_TOKEN" -o result.docx

Xhumanisa nedokhumende

Umbuzo mayelana nemisebenzi eqediwe. Izixazululo zikhona kuphela embhalweni okhishwayo futhi zisho ikhasi lomthombo. Kudinga i-akhawunti ye-token - izici zokuxoxa ziyi-akhawunti ezi-gated.

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

curl -X POST https://ocr.chat/api/v1/chat/9f2c1b7e4a.../ \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"message": "What is the invoice total and due date?"}'

Ibuyisela umlayezo we-assistant nge-response yayo nohlu lwekhasi elibhalwe phansi:

{"conversation": "a1b2…", "message": {
   "role": "assistant",
   "content": "The total is $42, due on March 3 (p. 1).",
   "citations": [{"page": 1, "snippet": "The invoice total is $42…"}]
}}

GET /api/v1/chat/<uuid>/history/, thola ukuxhumana okuphelele kwe-transcript yomsebenzi.

Imibuzo ebuzwa kaningi

Create a free account and open your account page, your token is shown there with a copy button.

Yes, files of 5 pages or fewer return the full result inline in the POST response, so no polling is needed for most images and short PDFs.

Over 100, including Latin, CJK, Arabic, Cyrillic and Indic scripts. Use language=auto to detect, or pass a specific code.

Uploads are processed for OCR and deleted automatically. We never sell, share, or train on your documents.

Ukusetshenziswa kulinganiselwa ngekhasi ngalinye nge-akhawunti yakho: ukufona okungaziwa kuthola i-IP ngayinye yosuku ngalunye, ama-akhawunti amahhala athola i-buckle ngayinye, futhi ama-plans akhokhelwayo asebenzisa ama-credits athengiswe nge-file ngayinye yekhasi eliphakeme nesinqumo. Uma uphuma, uthola i-402 ne-used ne-cap engxenyeni.

Ungathumela i-PNG, JPG, WEBP, GIF, BMP, TIFF, ne-PDF enekhasi elilodwa. Izinkomba zilayishwe njenge-txt, md, docx, pdf (engakwazi ukusesha), csv, noma json nge-parameter yefomethi yendawo yokuqeda kukhuphula.

400 ihele elilahlekile, uhlobo olungaxhaswa, noma ihele likhulu kakhulu; 401 ihele noma i-token engasebenziyo; 402 ngaphandle kwekhasi; 404 umsebenzi ongaziwa UUID; ne 409 ukufaka okucelwe ngaphambi kokuba umsebenzi uqedwe. Izitho zephutha zifaka umlayezo omncane.

Ingxenye yomsebenzi enesimo, isigaba, ulwimi, ikhasi_lokubalwa, ne mean_confidence, kanye nombhalo ophelele nophawu. Ikhasi lokuhlanganisa lihlukanisa ikhasi ngalinye libe ngamabloki ngesihloko sabo, ibhokisi lokuqeda (ibhokisi le-b), ne-block confidence.

Sebenzisa i-cpu (iphutha) ukukwazisa okukhawulelayo, okuphansi kwedokhumende aphrintiwe. Sebenzisa i-vlm, i-premium AI engine, ukubhalela ngesandla, ukubukeka okunzima noma okuningi kwehlathi, i-matematics, nokuhumusha, lapho kulungile kakhulu khona.

Phatha ithuluzi nge-slug (njengesibonelo ukukhishwa kwethebula noma ukushicilelwa ngesandla kumbhalo) ukusebenzisa ithuluzi elisetshenzisiwe. Ngethuluzi lokuhumusha, thola i-translate_to nekhowudi yesilimi esithenjwa ukuze uthole umbhalo owaziwayo oguqulwe emuva.

Amafayela ayizikhasi eziyi-5 noma ambalwa abuyela ngaphakathi kwe-POST. Amafayela amakhulu abuyela emuva ngokushesha njenge-pending noma processing, futhi ukhetha GET /api/v1/ocr/<uuid>/ kuze kube isimo siqediwe noma sihlulekile. Ama-plans akhokhelwayo akhuphula ikhasi lefayela ngalinye.

I-API i-REST ecacile ngaphezulu kwe-HTTPS, ngakho isebenza kusuka kunoma iyiphi ulwimi ne-HTTP client - bona i-Python, i-Node.js, ne-cURL imiqondo engezansi. Akukho SDK yokufakela; ama-line ambalwa we-HTTP code standard yilokho odinga.
