Ensure you have installed the required package to use this SDK method.

Catalyst does not store any of the files you upload in its systems. The documents you upload are used for one-time processing only. They are not used for ML model training purposes either. Catalyst components are fully compliant with all applicable data protection and privacy laws.

Document Processing is only relevant to Indian users and is only available in the IN DC. This feature will not be available to users accessing from the EU, AU, US, JP, SA or CA data centers. Users outside of India from the other DCs can access the general OCR component to read and process textual content.
The CHEQUE model is a part of the Document Processing feature that enables you to process Indian bank cheque leaves as identity proof documents. This enables you to extract fields of data from a cheque using an advanced OCR technology, and fetch the parameters recognized from the cheque through the response.
You must provide the path to the image file of the front page of the cheque book.
