generated: '2026-08-28' method: searched source: >- Direct HTTP probe of the /.well-known/ discovery surface on every host Mutual of America serves (2026-08-28). Mutual of America publishes no baseURL and no OpenAPI, so the host set was derived from the corporate website, the plan administration portal and the customer identity host. note: >- Two real documents were retrieved, both on login.mutualofamerica.com — the company's OpenID Connect and OAuth 2.0 authorization-server metadata. That host is an Okta Customer Identity tenant running on a Mutual of America custom domain (issuer is https://login.mutualofamerica.com), so the documents are served by a host the company controls. It is a workforce/customer sign-in surface for the retirement plan portal, NOT a public API. The corporate site (www.mutualofamerica.com, Optimizely/EPiServer CMS) returns a clean HTML 404 for every /.well-known/ path. sponsor.mutualofamerica.com sits behind an Imperva "Pardon Our Interruption" bot interstitial that answers HTTP 200 with a 6,183-byte HTML challenge page for EVERY path probed — those 200s are recorded below as soft-200 challenges and are explicitly NOT documents. hit_count: 2 soft_404_control: host: https://www.mutualofamerica.com path: /.well-known/this-path-does-not-exist-ae-control status: 404 bytes: 18076 note: >- The corporate host returns a genuine 404 status with its branded 18,076-byte error page, so the 404s recorded below are true negatives rather than a catch-all. soft_200_control: host: https://sponsor.mutualofamerica.com status: 200 bytes: 6183 content_type: text/html; charset=UTF-8 body_marker: 'Pardon Our Interruption' note: >- Imperva bot-mitigation interstitial. Returns the identical 200/HTML body for /.well-known/agent-card.json, /.well-known/agent.json, /openapi.json and /swagger.json.
