Clementine

Clementine (Clementine Labs) was a New York based enterprise communication startup founded in 2013 and publicly launched in September 2014, offering workplace messaging, chat, and conference calling that let colleagues reach each other without exchanging personal mobile phone numbers. It appears on the Andreessen Horowitz investment list and was acquired by Dropbox in April 2016, after which the Clementine service was shut down and the team folded into Dropbox collaboration efforts. The company operates no public API, developer portal, documentation, or SDKs today: its primary domain, clementine.io, now issues an HTTP 301 redirect to dropbox.com. This profile is retained as a historical, non-operational record in the API Evangelist network.

Clementine is profiled on the APIs.io network. Tagged areas include Company, Acquired, Defunct, Enterprise Communication, and Messaging.

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/clementine: open an issue to ask a question, or submit a pull request to add artifacts.
