Atlas automatically classifies and extracts structured data from a wide range of documents used in financial workflows. You do not need to declare a document type at upload time — Atlas detects it from the image content and returns the appropriate fields in the `document_type`-specific payload within `ocr_data`. Each document type returns a distinct set of extracted fields, all following the same `{ "value": ..., "confidence_score": ... }` structure. For the full list of fields per document type, see [Supported Documents](/resources/supported-documents). ## Document categories These documents establish individual identity and are used for KYC verification in lending applications. | Document type | Description | | ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `AADHAAR` | Indian national identity card.

For example, an `AADHAAR` document returns `name`, `address`, `aadhaar_number`, and `date_of_birth`, while an `INVOICE` returns `customer_name`, `dealer_address`, `total_invoice_amount`, and so on. Your processing logic should branch on `document_type` to read the correct fields. ```json theme={null} { "ocr_data": [ { "document_id": "doc-001", "error_code": "", "error_reason": "", "data": { "document_type": "PAN", "name_as_per_pan": { "value": "D MANIKANDAN DURAISAMY", "confidence_score": 0.95 }, "pan_number": { "value": "PLZPM5601F", "confidence_score": 0.99 }, "dob": { "value": "16/07/1986", "confidence_score": 0.98 }, "document_quality_flag": { "value": "original", "confidence_score": 0.97 } } } ] } ``` ## Extraction failures If Atlas cannot extract data from a document, the `data` object will be empty or partially populated, and the `error_code` and `error_reason` fields will contain a machine-readable code and a human-readable explanation. ```json theme={null} { "document_id": "doc-002", "error_code": "UNRECOGNISED", "error_reason": "document not in list", "data": {} } ``` Common error codes include `UNRECOGNISED` (document type not supported) and `INVALID_DOC` (document could not be processed, for example due to image quality or multiple subjects in frame).
