  title: AroPay API
  version: 1.0.0
  description: |
    The AroPay API for orchestrating sealed, private payments on public
    ledgers, built on the Aro Confidential Rails (Zama Protocol FHE). The
    current deployment is an MVP sandbox for B2B users on Ethereum Sepolia,
    with Mainnet to follow.

    Every response (except the flat Sandbox probes)
    uses the shared envelope: `{ "ok": true, "data": … }` on success and
    `{ "ok": false, "error": { "code", "message", "details?" } }` on failure.

    Amounts are decimal strings in human units (e.g. `"125.50"`). Write
    requests must send `Content-Type: application/json`.
