Newcastle Permanent Building Society
Newcastle Permanent Building Society is a customer-owned Australian authorised deposit-taking institution (ADI) founded in 1903 and headquartered in Newcastle, New South Wales. As a mutual, it is owned by its members rather than shareholders, and it provides retail banking, home loans, savings, term deposits, and insurance to communities across NSW. In March 2023 it merged with Greater Bank to form Newcastle Greater Mutual Group (NGM Group), one of Australia's largest customer-owned banks, while Newcastle Permanent continues to operate as a consumer brand. As a regulated ADI it is a data holder under Australia's Consumer Data Right (CDR / Open Banking) and exposes a live, public, unauthenticated Product Reference Data (PRD) API conforming to the Data Standards Body Consumer Data Standards, alongside an NPBS Innovation Sandbox and Marketplace developer portal.
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 Newcastle Permanent Building Society the way a machine reads it — 18 machine-readable artifacts across 14 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 — Newcastle Permanent Building Society scores 52.6/100 (developing), with a separate agent-readiness read of 55/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
