  note: >-
    Adelphic publishes no public OpenAPI and no self-service developer auth
    reference. This profile records what was directly observed by probing the
    live API host api.adelphic.com — a gated enterprise endpoint (Java servlet
    container; JSESSIONID cookie) protected by HTTP Basic authentication.
    api.viantinc.com returns the byte-identical 401 with the same
    `Basic realm="Adelphic"` challenge, confirming the two names front the same
    Adelphic API service. Access requires Viant/Adelphic account credentials;
    there is no public key issuance and no OAuth or OIDC discovery document
    (/.well-known/oauth-authorization-server and
    /.well-known/openid-configuration return 401 on the API host and 404 on the
    web hosts).

    Every path probed on api.adelphic.com — /, /openapi.json, /swagger.json,
    /v1/openapi.json, /api-docs, /docs, /redoc and all /.well-known/* — returns
    401. The contract is behind the credential wall, not absent.
