🇺🇸Banking & Open Banking in United States

127 banking & open banking providers in United States, publishing 544 APIs.

127 providers 544 published APIs 547 indexed documents

Banking & Open Banking in United States — 127 providers on the APIs.io network sit in both cohorts, and between them they publish 544 indexed APIs.

59 of the 127 publish at least one machine-readable API; 68 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 56 minimal, 42 emerging, 12 developing, 11 thin, 4 strong, and 2 exemplar.

Leading by rating: Plaid, Dwolla, Cash App, Highnote, Dun & Bradstreet, Bond, and 121 more.

Country membership reads a tag, a stated headquarters or a stated nationality. A provider lands in United States when one of its own top-level tags names the country, when its own description states a headquarters that names the country or one of its cities, or when it describes itself by nationality (“a French company”; roadmap#542, #719). Region words (“Latin American”), language uses (“French-speaking”) and a city named outside a headquarters statement are not counted, so this cell is a floor, not a census.

This page is the intersection of two independently computed cohorts: United States and Banking & Open Banking. A provider appears here only when it is already a member of both. United States membership is matched on tag, stated HQ, so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.

Work with this as data

Every country here is available over the APIs.io API and to AI agents over MCP. Countries is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
