Barclays US is the United States consumer banking arm of Barclays PLC, operated through Barclays Bank Delaware, a Delaware state-chartered bank headquartered in Wilmington. Doing business as Barclays US (barclaysus.com redirects to cards.barclaycardus.com), it is one of the largest co-branded credit card issuers in the country, running highly customized card programs for major travel, airline, retail, and affinity partners (JetBlue, American Airlines, Wyndham, AARP, Gap, and others), alongside small-business cards, installment loans, point-of-sale financing, and a direct-to-consumer online savings and CD franchise. Unlike Barclays UK — which operates a mandated PSD2 Open Banking API Exchange at developer.barclays.com — the US consumer entity publishes no first-party public developer portal or downloadable API specification. US open finance is voluntary and fragmented, so consumer- permissioned account and card data from Barclays US is reached in practice through third-party data aggregators rather than a documented first-party API. No FDX-conformant data-access endpoint or formally stated CFPB Section 1033 posture is published on the US site as of this profile.
