HSBC USA

HSBC USA is the United States arm of HSBC Holdings plc, operating principally through HSBC Bank USA, N.A., a nationally chartered bank supervised by the Office of the Comptroller of the Currency (OCC). After exiting mass-market domestic retail banking in 2022 — selling its East Coast branches and national online deposit business to Citizens and its West Coast branches to Cathay Bank — HSBC refocused its US operations on global wholesale, commercial and corporate banking, global banking and markets, and wealth management for internationally connected clients. On the open-finance front, HSBC USA does not publish a US-specific first-party developer program; public API access is provided through HSBC's group-wide corporate and institutional Developer Portal (developer.hsbc.com), whose transaction-banking API products serve US wholesale clients but require registration and login to reach the actual API reference and specifications. There is no publicly downloadable OpenAPI, and consumer-permissioned data access for remaining US accounts is mediated through third-party aggregators rather than a documented first-party consumer data-sharing API.

HSBC USA publishes 2 APIs on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Corporate Banking, and Transaction Banking.

HSBC USA’s developer surface includes documentation, support, and 13 more developer resources.
