InMobi Exchange (OpenRTB 2.5)

name: InMobi Exchange (OpenRTB 2.5)
description: InMobi's programmatic ad exchange, integrated by demand-side platforms over the IAB OpenRTB
  2.5 protocol. InMobi publishes its own delta specification ("InMobi Open RTB 2.5 Specification Version
  4.3") plus an OpenRTB Native Ad Specification v1.2. HTTP/1.1 POST with application/json payloads, gzip
  supported on both bid requests and bid responses, and a tmax auction timeout. Bidder endpoints are provisioned
  per DSP partner during onboarding, so InMobi publishes no public base URL for this surface.

  note: No baseURL is recorded because InMobi provisions bidder endpoints per DSP partner; inventing one
    would be a fabrication. The specification is published as PDF, not as a machine-readable contract.
