Commerce Bank
Commerce Bank is the principal banking subsidiary of Commerce Bancshares, Inc. (NASDAQ CBSH), a Missouri-based regional bank holding company with roughly $32 billion in assets and dual headquarters in Kansas City and St. Louis. Commerce Bank is a Missouri state-chartered bank and Federal Reserve member, founded in 1865, offering personal, business, commercial, and wealth-management services across the U.S. Midwest. Its API posture is corporate/embedded-banking oriented rather than a fully open public program: it runs a registration-gated external developer portal (developers.commercebank.com) and a CommercePayments developer platform, and delivers ERP-embedded banking via Commerce Connections Direct. Consumer-permissioned data sharing is largely intermediated through aggregators such as Plaid and platforms like Modern Treasury rather than a documented first-party, self-serve open-banking API. No public FDX or CFPB Section 1033 data-access posture is documented, and no downloadable OpenAPI/Swagger is publicly available.
Commerce Bank is listed with 1 API on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Regional Bank, and Payments.
Commerce Bank’s developer surface includes engineering blog, support, and 8 more developer resources.

Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
