TrustBiz

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.

MCP server (recommended)

Streamable-HTTP MCP endpoint with one tool, verify_business(query):

https://trustbiz.org/api/mcp

// Claude Code
claude mcp add --transport http trustbiz https://trustbiz.org/api/mcp

// any MCP client config
{ "mcpServers": { "trustbiz": { "url": "https://trustbiz.org/api/mcp" } } }

REST

GET https://trustbiz.org/api/v1/verify?q=<query>

// query can be: business name · GSTIN · TB-certificate id · UPI ID · @handle · phone
// → { verdict: "verified" | "not_verified" | "upi_warning",
//     summary, businesses: [{ certificate_id, business_name, verification,
//     verified_checks[], verify_url, ... }], disclaimer }

Semantics your agent should honour

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.
