To use Foursquare's data for real-time bidding, you can install our Campaign On-Prem SDK -- a self-hosted software solution that runs on your hardware. On-Prem is designed to operate in low-latency, high-volume environments where network latency precludes hosted options.

There are two different types of implementations: a Java library for lower-level integration and an HTTP Server that provides a RESTful interface.
