summary: Get Usd Balance
description: 'Wise USD settlement account balance for the Treasury dashboard.
Zero-state: no inbound payments received, so balance is Decimal("0").
Response key names mirror the sandbox reference (see
src/merchant0/sandbox/mock_fintech_app.py get_usd_balance) so the
Treasury dashboard frontend consumes the same shape regardless of
which surface it calls.
IPA v2.0 specified endpoint. USD_SETTLEMENT_ACCOUNT = KEY 17 (future
VaultManager wiring). Manual harvest: CEO converts USD to PHP via
the Wise app; Merchant-0 does not perform the conversion.'
