Marcus Consumer Data Access (Aggregator-Only)
Marcus by Goldman Sachs does not publish a first-party consumer developer API. Consumer-permissioned account data is available only through third-party open-finance aggregators. Plaid supports Marcus with the Assets, Auth, Balance, Transactions, and Investments products across Depository, Loan, Investment, and Other account types (US only). This entry is an honest data-access pointer, not a Marcus-operated API.
