source: >-
  Live probes of olyns.com and every discovered Olyns host, plus a read of the public
  marketing, terms and partner pages. Olyns publishes no OpenAPI, AsyncAPI, GraphQL SDL,
  gRPC or WSDL contract, so every API-contract conformance assertion below is answered
  from an absence of contract rather than from a spec.
note: >-
  REWARD-ONLY. Nothing here is scored against Olyns for being false. The single true
  entry is a domain standard Olyns genuinely serves for its retail-media business — the
  IAB Tech Lab authorized-sellers declaration — and it is recorded because it is the only
  machine-readable, standards-governed document Olyns publishes anywhere on its own domain.
conformance:
- id: iab-ads-txt
  name: IAB Tech Lab ads.txt (Authorized Digital Sellers)
  conforms: true
  evidence:
    url: https://olyns.com/ads.txt
    status: 200
    content_type: text/plain
    observed: >-
      A well-formed ads.txt declaring ownerdomain=olyns.com, managerdomain=screenversemedia.com,
      and a single DIRECT authorized-seller record for screenversemedia.com. This is the
      machine-readable counterpart to Olyns' published partnership with Screenverse to sell
      its digital-out-of-home Cube screen network on programmatic platforms.
    note: >-
      The same document is also served at https://olyns.com/ads-txt (200). No app-ads.txt is
      published (https://olyns.com/app-ads.txt returns 404), which is the expected result for
      a DOOH-only inventory owner with no in-app ad inventory.
  domain_standard: true
  market: digital-out-of-home / programmatic advertising
- id: openrtb
  name: IAB OpenRTB
  conforms: false
  evidence:
    observed: >-
      Olyns' DOOH inventory is transacted programmatically, but through Screenverse as the
      manager/SSP — Olyns itself exposes no bid endpoint, no OpenRTB request/response schema
      and no supply-side contract on any host it controls. The OpenRTB surface, if any,
      belongs to screenversemedia.com, not to Olyns.
- id: oauth2
  name: OAuth 2.0
  conforms: false
  evidence:
    observed: >-
      No /.well-known/oauth-authorization-server or /.well-known/openid-configuration is
      served on any Olyns host (see well-known/olyns-well-known.yml). Sign-in for the consumer
      wallet app and the self-service ad portal is a first-party form; no OAuth surface is
      published to third parties.
- id: rfc9457
  name: RFC 9457 Problem Details for HTTP APIs
  conforms: false
  evidence:
    observed: No public API contract exists to declare a problem+json error envelope.
- id: rfc8594
  name: RFC 8594 Sunset / Deprecation headers
  conforms: false
  evidence:
    observed: No public API and no published deprecation policy.
- id: rfc9116
  name: RFC 9116 security.txt
  conforms: false
  evidence:
    url: https://olyns.com/.well-known/security.txt
    status: 404
    observed: Probed on all four Olyns hosts; not served anywhere.
