DataSift (MediaSift Inc.)

DataSift (MediaSift Inc.) was a pioneering social data platform that provided real-time and historical access to social media firehoses (Twitter, Facebook Topic Data, and more) through its CSDL filtering language and its Push, Historics, and Managed Sources REST APIs. Founded in 2007 and backed by Insight Partners and others, the company was acquired by Meltwater in 2019; the datasift.com domain now redirects to meltwater.com and the standalone DataSift developer platform and APIs have been discontinued. Official first-party client SDKs for Python, Ruby, PHP, Java, and Node.js remain published on public package registries under the datasift GitHub organization as historical artifacts.

DataSift (MediaSift Inc.) is profiled on the APIs.io network. Tagged areas include Company, Consumer, Social-Media, Social Data, and Data.

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/datasift-mediasift-inc: open an issue to ask a question, or submit a pull request to add artifacts.
