Great-West Lifeco
Great-West Lifeco Inc. is a Winnipeg-headquartered international financial services holding company and a member of the Power Corporation group, and one of the largest life insurers in North America. It operates through Canada Life in Canada, the United Kingdom, the Isle of Man and Germany, through Irish Life in Ireland, and through Empower in the United States, spanning individual and group life, health and dental, disability and critical illness insurance, annuities and payout products, segregated funds and wealth management, employer-sponsored retirement recordkeeping, and life reinsurance. Its home market is Canada, where it is federally supervised by OSFI for prudential matters while market conduct is regulated province by province, and where no open-insurance mandate exists (Consumer-Driven Banking excludes insurance outright). Its API posture reflects that absence of a forcing function: the Great-West Lifeco corporate site and the Canadian consumer site canadalife.com publish no developer portal and no API documentation, and probes of developer/docs subdomains and /developers, /api, /developer, /partners and /integrations paths return no such surface. Two production API surfaces nevertheless exist inside the group, both partner-gated and unrelated to each other. Canada Life runs an Apigee gateway at api.canadalife.com that serves a real OpenID Connect discovery document anonymously - issuer, JWKS, token, revocation and userinfo endpoints, with the authorization endpoint deliberately published as "authorize-NOT-SUPPORTED" and an empty scopes_supported array - and whose error envelopes point to https://apimarketplace.canadalife.com, a digitalML-hosted API marketplace that does not resolve publicly. The U.S. retirement subsidiary Empower runs a genuine developer portal that lists two production APIs publicly while naming eight API products plus three coming soon on its marketing site, places every piece of reference documentation behind login, documents an x-api-key header with OAuth 2.0 client_credentials and private_key_jwt in support of FAPI, publishes release notes, a maintenance window and a mock-data sandbox, and issues credentials only after a reviewed access request. There is no downloadable OpenAPI anywhere, no public Postman collection, no SDK, no MCP server, no webhook or event catalog, and no ACORD, AL3 or IVANS reference on any public property in the group.
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 Great-West Lifeco the way a machine reads it — 7 machine-readable artifacts across 3 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 — Great-West Lifeco scores 43.4/100 (developing), with a separate agent-readiness read of 9/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Great-West Lifeco
Each block below is one kind of artifact we hold for Great-West Lifeco. 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 3
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.

Security Posture 3
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.

This is an independent, third-party profile of Great-West Lifeco, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
