Halo Collar

aid: halo-collar
name: Halo Collar
description: 'Halo Collar is the consumer GPS dog-fence and dog-tracking product built by Protect Animals With Satellites
  LLC (d/b/a Halo), founded in 2017 by Ken Ehrman, Michael Ehrman and dog behaviorist Cesar Millan. The product pairs a cellular-
  and GPS-connected smart collar (currently Halo Collar 5, with Halo Collar 4 still sold) with a companion iOS/Android app
  that lets an owner draw virtual GPS fences, watch real-time location, trigger Cesar Millan-designed training feedback, and
  read activity reports. The service runs on a required Pack Membership subscription in Bronze, Silver and Gold tiers that
  carries unlimited cellular data, an increasing virtual-fence allowance, accessory discounts and third-party partner perks.
  Halo publishes no public developer program: the app is served by a first-party, undocumented backend at api.halocollar.com
  (an ASP.NET service that self-identifies as Halo.Web.Api), and there is no developer portal, API reference, OpenAPI/AsyncAPI/GraphQL
  contract, SDK or webhook surface anywhere on the company''s public web properties.'

  detail: 'Halo sells an end-user GPS dog collar and app: its only API host, api.halocollar.com, is the private ASP.NET backend
    for the mobile app (it answers 200 with a "Halo.Web.Api" service banner and a JSON 404 envelope on every other path),
    and there is no developer portal, no API reference, no SDK and no docs./developer. host in DNS at all.'
