The Guardian Life Insurance Company of America is one of the largest mutual life insurance companies in the United States, providing life insurance, disability income insurance, dental insurance, and other employee benefits. Guardian operates a partner developer portal, Guardian Connect, built on Apigee, exposing a catalog of group and retail insurance APIs covering evidence of insurability, member benefits enrollment, policy and plan configuration, group rating and quoting, dental provider directory and verification of benefits, underwriting data, and life illustration. The Member Benefits APIs implement the LIMRA Data Exchange (LDEx) Standards. Access is partner-gated: a partner agreement is established first, after which Guardian issues a registration code and partner key, and API keys are minted per partner app subject to administrator approval. Authentication is JWT with OpenID Connect login. No OpenAPI, Swagger, or other machine-readable contract is published publicly — the API reference sits behind partner login — so the APIs below are recorded from Guardian's own public catalog descriptions.
Guardian Life is listed with 15 APIs on the APIs.io network. Tagged areas include Insurance, Life Insurance, Disability Insurance, Dental Insurance, and Employee Benefits.
Guardian Life’s developer surface includes API reference, getting-started guide, FAQ, support, and 10 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Insurance regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
Machine-Readable Auth+10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
13 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

platform: Apigee developer portal on Drupal (apigee_edge module, guardian_apigee theme), identified from drupal-settings-json
on the rendered pages.
note: 'No OpenAPI, Swagger, GraphQL, or AsyncAPI document is publicly retrievable. API detail pages carry no spec link and
the reference sits behind OpenID Connect partner login, so every API above is recorded from Guardian''s own public catalog
description with no baseURL asserted and no contract scaffolded. Onboarding is approval-gated: a partner agreement precedes
account creation, and per-app API keys require administrator approval.'
observed_defect: https://developer.guardianlife.com/faq renders raw Drupal PHP warnings and deprecation notices to anonymous
visitors, disclosing module paths, internal module names (glic_contact_us), core file paths, and a user permissionsHash.
Reported here as an observation for provider outreach, not scored.
x-coverage:
contracts: none-published
reason: Guardian publishes a named, described API catalog publicly but gates every machine- readable contract behind partner
login. This is a provider-side disclosure boundary, not a harvest failure.
