description: 'Zefr is an ad-tech content intelligence company that classifies social video, image, audio and text so advertisers
  can buy and measure media against brand safety and suitability standards. Its classification engine labels content across
  YouTube, Meta (Facebook and Instagram), TikTok, Snapchat, Google Ads and DV360 against the 4A''s and GARM frameworks, and
  its Brand Suitability Suite gives brands pre-bid controls and post-bid measurement from a single console. Zefr has no public
  developer program: production API infrastructure exists (api.zefr.com is a Google Apigee gateway, alongside api2.zefr.com
  and api-eu1.zefr.com) but no developer portal, API reference or machine-readable contract is published anywhere, and access
  runs through a demo request. The only machine-readable documents Zefr serves publicly are the OpenID Connect and OAuth 2.0
  Authorization Server Metadata discovery documents on its Auth0 custom domain, login.zefr.com.'

  detail: Zefr runs live API infrastructure — api.zefr.com is a Google Apigee gateway that answers every anonymous request
    with a proprietary ApplicationNotFound fault — but publishes no developer portal, no API reference and no machine-readable
    contract; developer.zefr.com and docs.zefr.com do not resolve, the /support page renders the placeholder "Waiting on Content
    Entry...", and the only route to the platform is the "Request a Demo" form.
