​
Overview

The Balansas Customer API is a RESTful API for the Balansas Banking-as-a-Service platform. It lets you open accounts, onboard end users, move money, manage wallets, and subscribe to real-time events over EU Rails (powered by Fiat Republic). Every response shares a consistent envelope: 
{
  "data": { },
  "meta": { "pagination": { "page": 1, "limit": 25, "total": 100 } }
}
Errors return a structured envelope instead: 
{
  "error": { "code": "validation_error", "message": "Human-readable message", "details": {} }
}
See Response format and Errors for the full contract.
