Northern Trust
Northern Trust is a Fortune 500 global financial services firm providing asset servicing, asset management, wealth management, and banking to corporations, institutions, family offices, and individuals worldwide. Its first-party developer program, the Northern Trust API Store at developer.ntrs.com, exposes asset-servicing capabilities as REST APIs across custody, fund accounting, transfer agency, middle office, data management, and risk and performance, plus an event-notification service. The catalog is a partner/registration surface: browsing product domains is public, but API reference specifications (downloadable as spec.json) and live access sit behind Okta-based OIDC login. Northern Trust does not publish a public consumer open-banking API; retail account connectivity is reached indirectly through data aggregators.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Northern Trust the way a machine reads it — 11 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 — Northern Trust scores 38.9/100 (thin), with a separate agent-readiness read of 19/100 (agent aware). 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 Northern Trust
Each block below is one kind of artifact we hold for Northern Trust. 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.

Event Specifications 1
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.

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.

Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
