How It Works

Upload image (multipart or base64 JSON)
Multiple OCR layers process image in parallel
Fields parsed from raw text using document-specific regex
Results merged via weighted consensus per field
Each field validated (format, checksum, date range)
Response: extracted fields, confidence score, review recommendation
