generated: '2026-08-22' method: probed source: https://auth.houm.com/.well-known/openid-configuration name: Houm standards conformance note: >- Assertions below are drawn only from documents Houm actually serves. Houm publishes no OpenAPI, no API reference and no compliance/trust page, so every contract-level and compliance-level standard is recorded as not-conformant-on-the-evidence rather than assumed. No domain standard for the real-estate market (RESO Data Dictionary / RESO Web API, MISMO, OSCRE) is declared by any Houm-served document; this is reward-only, so its absence is not a penalty — it is simply unmeasured because Houm ships no contract to measure. entries: - id: oidc name: OpenID Connect Core 1.0 Discovery conforms: true evidence: >- https://auth.houm.com/.well-known/openid-configuration returns HTTP 200 with a complete discovery document — issuer, authorization_endpoint, token_endpoint, userinfo_endpoint, jwks_uri, subject_types_supported, id_token_signing_alg_values_supported, response_types_supported. Saved verbatim to well-known/houm-openid-configuration.json. - id: oauth2 name: OAuth 2.0 (RFC 6749) + Authorization Server Metadata (RFC 8414) conforms: true evidence: >- https://auth.houm.com/.well-known/oauth-authorization-server returns HTTP 200 with the RFC 8414 metadata document; grant_types_supported includes authorization_code, client_credentials, refresh_token and urn:ietf:params:oauth:grant-type:token-exchange. - id: oauth2-pkce name: PKCE (RFC 7636) conforms: true evidence: 'code_challenge_methods_supported: ["S256","plain"] in the discovery document.' - id: oauth2-device name: OAuth 2.0 Device Authorization Grant (RFC 8628) conforms: true evidence: >- device_authorization_endpoint https://auth.houm.com/oauth/device/code and grant type urn:ietf:params:oauth:grant-type:device_code declared in the discovery document. - id: jwks name: JSON Web Key Set (RFC 7517) conforms: true evidence: https://auth.houm.com/.well-known/jwks.json returns HTTP 200 with an RSA sig key set. - id: fapi name: Financial-grade API (FAPI 1.0/2.0) conforms: false evidence: >- Not claimed and not supported by the metadata — the tenant advertises the implicit and resource-owner-password grants and token_endpoint_auth_method "none", all of which FAPI prohibits. - id: rfc9116 name: security.txt (RFC 9116) conforms: false evidence: >- /.well-known/security.txt returns 404 on houm.com, auth.houm.com and help.houm.com, and 403 on api.houm.com. See well-known/houm-well-known.yml. - id: rfc9457 name: Problem Details for HTTP APIs (RFC 9457) conforms: false evidence: >- Unmeasurable — no public API or error reference is published. api.houm.com returns a bare {"message":"Forbidden"} AWS API Gateway envelope, which is not application/problem+json. - id: openapi name: OpenAPI Specification conforms: false evidence: >- No OpenAPI/Swagger document found at any probed location on houm.com, api.houm.com, docs.houm.com, help.houm.com or blog.houm.com. See x-coverage in apis.yml. - id: reso-web-api name: RESO Web API / RESO Data Dictionary (real-estate domain standard) conforms: false evidence: >- No RESO OData $metadata surface, Data Dictionary reference, or RESO membership claim appears on any Houm-served page. RESO is a North American MLS standard and Houm operates in CL/MX/CO, so its absence is expected rather than a gap; recorded for completeness only.
