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.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Customers Bank the way a machine reads it — 15 machine-readable artifacts across 10 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Customers Bank scores 47.7/100 (developing), with a separate agent-readiness read of 80/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
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.

How we profile Customers Bank
Each block below is one kind of artifact we hold for Customers 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 10
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.

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
