One hub, every connection

What the API Hub does.

It gives partners, apps and AI agents one safe front door to your bank. Ready-made APIs, customer consent and monitoring are built in, so new partnerships go live in days.

Ready-made APIs

Accounts, payments, loans and KYC, exposed safely.

Payment & identity rails

ACH, FedNow, open banking, SSN and EIN checks, UPI, Account Aggregator, eKYC, Aadhaar and GST.

Partner portal

Sandbox, keys and documentation for fintech partners.

Ready for AI agents

APIs that AI agents can call safely, with consent and logs.

AI watches every API call.

An AI monitoring agent learns normal traffic for each partner. Unusual spikes are throttled and reported with the full log, before they become a risk.

Questions banks ask us.

Does it support open banking and Account Aggregator?

Yes. We build consent-based data sharing for open banking and the Account Aggregator framework, with consent checked on every call.

We already have an API gateway. Do we replace it?

No. The hub can sit behind your existing gateway and add the APIs, consent and partner portal.

How do AI agents use the APIs safely?

Agents call the same APIs as partners, with consent checks, limits and every call logged.

How is customer data protected?

Consent, encryption, rate limits and monitoring on every call, with data kept in your systems.
