Metamarkets Group

Metamarkets was a real-time analytics platform for programmatic advertising, giving ad exchanges, SSPs, DSPs, and ad networks interactive dashboards over billions of daily bid, impression, click, and spend events. Its Real-time Data Ingestion (RDI) API accepted continuous streams of OpenRTB-based JSON event records over authenticated HTTPS POST, surfacing them in the Metamarkets dashboard within seconds. Founded in 2010 and the birthplace of the Druid analytics database (now Apache Druid), Metamarkets was acquired by Snap Inc. in 2017; its successor products live on as Rill Data. This profile enriches the dcvc portfolio lead from the surviving public documentation at docs.metamarkets.com.

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

Metamarkets Group’s developer surface includes documentation, getting-started guide, authentication, sandbox, and 8 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/metamarkets-group: open an issue to ask a question, or submit a pull request to add artifacts.
