Description

This API can extract and parse the text from an input Bank cheque book document image and return the information in JSON format. CTS-2010 format cheques from all major Indian banks are supported.

The legacy data processing model is being formally deprecated.

In order to ensure continued compliance with the Digital Personal Data Protection Act, 2023 (DPDP Act), we are implementing DPDP V3 (Consent-Driven Processing). Under this framework, clients are required to obtain explicit, informed, and verifiable consent from the data principal prior to accessing, processing, viewing, or storing any personal data through the platform. This regulatory transition may require modifications to existing configurations and workflows. Clients are advised to review and update their implementations to ensure ongoing compliance with applicable data protection obligations. Further information regarding this transition can be enquired here. Learn more about this change here.
