Business verification APIs for KYB and vendor checks
Business verification APIs confirm that a company, firm or MSME is real, active and the one you think it is. Start from whatever identifier you have (a GSTIN, a CIN, a PAN, a Udyam number, a TAN) and get the details on record (name, status and, for most checks, address and key dates) back in one call.
Procurement, lending, payments and marketplace teams call them during vendor, merchant and borrower onboarding, and again before large payments. Combine them, or order a full KYB report that runs several checks on one business.
