Documentation

The bank's core is one API on one host: customers and accounts, transfers on every rail, cards, lending, compliance, reporting and the ledger underneath them. This is its reference, generated from the contract the services are checked against.

Built on OpenAPI

The whole API is one OpenAPI 3.1 document (version 2026-09-05). Import it into Postman or Insomnia to explore, or generate a typed client from it. The services are checked against the same document on every change, so what it says is what the API does.
