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 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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.
