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, API reference, and 15 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: open an issue to ask a question, or submit a pull request to add artifacts.
