InMobi Exchange (OpenRTB 2.5) is one of 5 APIs that [InMobi](https://apis.io/providers/inmobi/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include OpenRTB, Exchange, and Programmatic. The published artifact set on APIs.io includes API documentation and an API reference.

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.
