Siri

Siri began as Siri Inc., a spinout of SRI International's CALO artificial-intelligence program, backed by Menlo Ventures and Morgenthaler Ventures. The company shipped an iOS virtual-assistant app in February 2010 and was acquired by Apple in April 2010. Siri now ships as Apple's built-in voice assistant across iPhone, iPad, Mac, Apple Watch, and HomePod. There is no independent public REST API or developer portal for Siri; the developer surface is SiriKit, an on-device Apple framework (Intents/App Intents) that lets iOS apps expose actions to Siri rather than call Siri as a web service.

Siri is profiled on the APIs.io network. Tagged areas include Company, Virtual Assistant, Voice Assistant, Artificial Intelligence, and Machine-Learning.

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

    the only developer surface is SiriKit, an on-device iOS framework, which is out of scope for the API catalog.
