How it is built
You read and use operating accounts through the API. Opening, freezing and closing them goes through your account manager; the lifecycle endpoints on
/v1/accounts apply to the accounts you open for your customers. The objects are explained under Account structure.
Currencies
USD
ACH, Fedwire, and SWIFT with US ABA routing and account number.
EUR
SEPA Credit Transfer and SEPA Instant with a dedicated IBAN.
GBP
Faster Payments with UK sort code and account number.
USD
- Send and receive third-party payments over ACH, Fedwire, and SWIFT
- Hold operating funds in your own legal entity’s name
- Track activity with transaction and balance reporting, statements, and account summaries
- Move funds between your Augustus accounts with internal transfers
- Earn interest on eligible account configurations, accrued daily and paid out monthly
EUR and GBP
EUR and GBP accounts follow the same account model as USD accounts: the same statuses and controls, internal transfers, and reporting.- Send and receive EUR over SEPA, and GBP over Faster Payments
- Account details are issued as DE, NL, or GB IBANs, plus a UK sort code and account number for GBP
Money in and money out
- Deposits arrive at the account’s address and are credited to its balance. Give a sender the details from
financial_addresses. See Deposits. - Payouts debit the account. Pass its ID as
account_id. See Payouts. - Payouts to another Augustus account settle on Augustus’s books instead of going out on a rail: the payout reaches
sentwithin seconds, the receiving account gets adeposit.settledevent, and both records carryrail: "internal". Statuses and webhooks are the same as for any other payout, and no configuration is needed. - Conversions move funds between your fiat and stablecoin accounts. See Conversions.
Status
Operating accounts use the status model shared by every Augustus account:pending, active, frozen, closed. See Account status.
Integration
All account endpoints sit under/v1/accounts and follow the same auth, error, and pagination conventions as the rest of the 2026-05-01 API.
Sandbox. All operating account flows are available in sandbox mode with simulated rail movements. See Sandbox Mode, or follow the end-to-end Simulations walkthrough.
