Metamarkets

Metamarkets built a real-time analytics platform for the programmatic advertising industry, giving ad exchanges, DSPs, SSPs, and publishers an interactive dashboard over billions of daily bid, impression, and spend events. Its Real-Time Data Ingestion (RDI) platform ingests well-formatted, standards-based ad-tech event data (adhering to OpenRTB 2.5, IAB guidelines, and ISO date/country/language/currency standards) over an authenticated HTTPS streaming endpoint and surfaces it in the Metamarkets dashboard within seconds for querying and analysis. Metamarkets was acquired by Snap Inc. in 2017; the primary metamarkets.com site is now defunct, but the legacy developer documentation for the RDI platform remains live at docs.metamarkets.com. Surfaced as a portfolio company of Anthemis and profiled in the API Evangelist network.

Metamarkets publishes 1 API on the APIs.io network. Tagged areas include Company, Advertising, AdTech, Analytics, and Real Time.

Metamarkets’ developer surface includes documentation, getting-started guide, support, CLI, authentication, sandbox, and 10 more developer resources.
