Marcus by Goldman Sachs

Marcus by Goldman Sachs is the U.S. consumer banking brand of The Goldman Sachs Group, launched in 2016 to offer no-fee high-yield Online Savings Accounts and Certificates of Deposit (CDs) directly to retail customers online. Deposits are held at Goldman Sachs Bank USA, a New York State-chartered bank and member of the Federal Reserve System, insured by the FDIC. After Goldman's broad retreat from consumer lending, Marcus no longer originates personal loans and now centers on digital deposit products. Marcus operates NO public first-party consumer developer API and runs no self-serve developer portal for its retail banking products; the Goldman Sachs Developer platform (developer.gs.com) serves institutional Transaction Banking and Marquee offerings, not Marcus consumer banking. Consumer-permissioned account data (balances, transactions, account/holder info) is reachable only through third-party open-finance aggregators such as Plaid, Flinks, and MX, not a documented Marcus API. As a bank chartered in the U.S., Goldman Sachs Bank USA is subject to the emerging CFPB Section 1033 personal financial data rights framework, but no first-party FDX-conformant Marcus developer interface is publicly documented as of this record.

Marcus by Goldman Sachs publishes 1 API on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Consumer Banking, and Neobank.

Marcus by Goldman Sachs’ developer surface includes support and 5 more developer resources.
