East West Bank

East West Bank is the California state-chartered commercial banking subsidiary of East West Bancorp, Inc. (NASDAQ EWBC), headquartered in Pasadena, California, with roughly $79.7 billion in total assets and more than 125 locations across the United States and Greater China. A Member FDIC institution and one of the few U.S. banks holding a full banking license in China, it specializes in cross-border U.S.-China commercial banking, treasury and Global Transaction Services (GTS). On the open-finance front, East West Bank runs a first-party developer portal ("Bridge Open Banking" at apiportal.eastwestbank.com) aimed at commercial clients, documenting APIs to manage sub-accounts, retrieve balances, transfer funds, and obtain commercial account information, with a sandbox of live test accounts; the program is early-stage ("more APIs coming soon") and gated behind sales onboarding, so no OpenAPI/Swagger is publicly downloadable. Consumer-permissioned data access is also available indirectly through the Plaid aggregator. No public FDX participation or CFPB Section 1033 posture is documented as of this profile.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile East West Bank

Each block below is one kind of artifact we hold for East West Bank. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 1

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.
