Bankjoy

Bankjoy is an end-to-end digital banking platform purpose-built for community banks and credit unions. Founded in 2014 and based in the Detroit metro area (Royal Oak, Michigan), the Y Combinator- and Bessemer-backed fintech delivers consumer and business online and mobile banking, online account opening, online loan origination, digital statements, and fraud tooling (FraudSense) to 85+ financial institutions serving more than one million members. Bankjoy's API-based technology integrates with banking cores including Corelation KeyStone (as its first Certified Partner) and Fiserv, plus 150+ partner integrations. It is a business-to-business SaaS provider and does not publish a public developer API or OpenAPI surface.

More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.

Kin Score

API Evangelist profiles Bankjoy the way a machine reads it — 2 machine-readable artifacts, 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 — Bankjoy scores 21.2/100 (emerging), with a separate agent-readiness read of 0/100 (human only). 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 Bankjoy

Each block below is one kind of artifact we hold for Bankjoy. 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.

Security 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.
