description: Lets a publisher request InMobi ads from its own servers rather than through the client SDK,
  using the InMobi ad-request/ad-response contract at /showad/v3.1. The caller is identified by an InMobi
  Property ID carried in the request payload rather than by an authentication header. Verified live 2026-08-12.

  note: Live routed ad-serving host; an empty request returns 204 No Content (no ad), which is correct
    behaviour rather than an error. The linked SourceCode repo is InMobi's own seven-language client for
    the prior "API 2.0" generation of this endpoint and has not been updated since 2016.
