info:
  title: Rex Banking-as-a-Service API
  version: 1.0.0
  summary: Embed real bank accounts, transfers, and collections into your product.
  description: |
    The Rex BaaS API lets you provision virtual bank accounts, move money
    between them, accept inbound transfers, and collect at merchant terminals —
    all under your own brand, backed by a real bank ledger.

    This reference covers every endpoint your integration will call. If
    you're just getting started, read **[Getting Started](/introduction)**
    and **[Authentication](/authentication)** first — most integration
    questions are answered there, not in the endpoint list.

    All endpoints are versioned under `/baas/api/v1` and return JSON. See
    **[Errors](/errors)** for the shared error envelope, and
    **[Sandbox vs. Live](/guides/sandbox-vs-live)** for how test and
    production credentials differ.
