Greater Bank

Greater Bank is a customer-owned Australian retail bank headquartered in Newcastle, New South Wales, offering everyday transaction and savings accounts, term deposits, home loans, personal loans, and credit cards to personal and business customers. In March 2023 Greater Bank merged with Newcastle Permanent to form Newcastle Greater Mutual Group (NGM Group), one of Australia's largest customer-owned mutual banking organisations, while continuing to trade under the Greater Bank brand. As an Authorised Deposit-taking Institution (ADI) it is a designated data holder under Australia's Consumer Data Right (CDR / Open Banking) and exposes a public, unauthenticated Product Reference Data (PRD) API conforming to the Data Standards Body (DSB) Consumer Data Standards. Consumer-data sharing beyond PRD runs on the accredited CDR data-recipient (ADR) model with OAuth2/OpenID Connect FAPI-profile security.

agent native

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score

API Evangelist profiles Greater Bank the way a machine reads it — 13 machine-readable artifacts across 7 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 — Greater Bank scores 44.3/100 (thin), with a separate agent-readiness read of 65/100 (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 Greater Bank

Each block below is one kind of artifact we hold for Greater 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 7

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.

Arazzo Workflows 2

Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Model Context Protocol servers that expose these APIs to AI agents.

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.

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.
