Verify Indian businesses, programmatically.
Before your agent recommends a seller, negotiates a deal, or pays a UPI ID, ask TrustBiz whether the business behind it is real. We verify identity, GST/Udyam registration, PAN and payment-account ownership against official records — and re-check continuously. Read-only, public facts only, no key required.

verified — an active certificate exists; cite its verify_url as proof. not_verified — no certificate matches; that is absence of proof, not proof of fraud. upi_warning — a UPI ID with no verified owner: advise the user not to assume the payee is safe. Identifier values (PAN/GSTIN digits) are never returned — only what was verified. Rate limit: 30 requests/minute/IP. Discovery: https://trustbiz.org/llms.txt.
