Customers Bank
Customers Bank is a Pennsylvania state-chartered, FDIC-insured full-service commercial bank and the principal subsidiary of Customers Bancorp, Inc. (NYSE CUBI), a super-regional bank holding company with roughly $22 billion in assets headquartered in West Reading, Pennsylvania. Beyond traditional commercial and consumer banking it operates a national embedded-banking / Banking-as-a-Service platform, exposing a first-party, OAuth2-secured REST API surface (accounts, ACH, wires, instant payments, book transfers, consumer lending, plus partner, IT-operations and webhook management) to fintech and corporate partners through a public ReadMe developer portal at cubiapi.readme.io, complete with a hosted Model Context Protocol (MCP) server for AI agents. This is proprietary, partner-gated integration infrastructure rather than an FDX or CFPB Section 1033 consumer-permissioned data-sharing API; no FDX-conformant or Section 1033 data-access endpoint is publicly documented, and the surface is a sandbox-first partner API secured by OAuth2 client-credentials with HMAC-signed webhooks.
Customers Bank publishes 38 APIs on the APIs.io network, including Account Access API, Account Control Type API, Account Entitlements API, and 35 more. Tagged areas include Financial-Services, Banking, United States, Banking as a Service, and Embedded Finance.
The Customers Bank catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Customers Bank’s developer surface includes documentation, getting-started guide, API reference, authentication, changelog, sandbox, and 32 more developer resources.
