APIs for Fintech & NBFC
Built for Digital India
The complete API stack for Indian fintech companies and NBFCs — KYC automation, UPI validation, bank account verification, and real-time fraud detection. Reduce onboarding time by 80%, block fraud before it hits, and stay compliant with RBI guidelines.
What's Slowing Down Indian Fintech
Indian fintech is growing faster than any market in the world. But most fintech companies hit the same four walls as they scale:
1. Manual KYC is killing conversion. Document upload + manual review takes 4 to 24 hours per customer. Users drop off. Applications lose momentum. CAC goes up, revenue goes down.
2. Failed disbursements drain resources. Wrong account numbers, closed accounts, name mismatches — 8-12% of loan disbursements fail on the first attempt. Each one costs support hours and reconciliation effort.
3. Fraud is proactive, not reactive. Fake accounts, synthetic identities, and mule accounts get through because verification happens after onboarding. By the time fraud is detected, the money is gone.
4. Vendor sprawl slows everything down. One vendor for KYC, another for bank verification, another for fraud scoring — each with their own API key, dashboard, invoice, and support team. Integration takes weeks. Maintenance never stops.
API Express solves all four.
The Fintech Stack — 4 APIs, One Key
This is what 90% of Indian fintech companies use on API Express. Start with any API, add more as you scale.
Verification API (KYC)
RBI-compliant identity verification with real-time government database access. Aadhaar OTP in 2-5 seconds, PAN in under 3 seconds. Cuts onboarding time from days to seconds.
UPI / Bank Verification
Validate bank accounts and UPI IDs before disbursement. Confirm beneficiary name matches. Eliminate failed payouts and reduce reconciliation cost from day one.
Cyber Security Verification
Score every loan application or signup in under 200ms. Detect synthetic identities, compromised credentials, and account farming before they complete. Reduce fraud losses by 40-70%.
Vehicle RC Verification
Instant verification of vehicle registration, owner details, insurance status, and chassis number — essential for loan-against-vehicle and used-car financing workflows.
From Signup to Disbursement in Under 30 Seconds

User provides PAN, Aadhaar, bank account details, and expected loan amount. Takes 60 seconds on a mobile device.
