Validate GSTINs and detect document fraud

The agent verifies the authenticity of Indian GSTINs and checks for fabricated invoices, duplicate entries, or amount anomalies, ensuring compliance and preventing financial fraud.

How it works

Read-onlyFinance and payments

The agent takes a GSTIN or a set of documents and uses the validate_gstin tool to check format and check-digit validity. For deeper analysis, it uses detect_document_fraud to identify fabricated GSTINs, duplicate invoice numbers, or amount anomalies. The agent should ensure the input GSTINs or document URLs are provided and that the user understands this is a verification step. It then reports the validation verdict or fraud indicators found in the documents.
