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.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
Siri is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Siri scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Siri is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
