Calm
Calm is an American digital wellness company headquartered in San Francisco that builds a mobile and web app focused on mindfulness, meditation, sleep, and mental health. Founded in 2012 by Michael Acton Smith and Alex Tew, Calm offers guided meditations, Sleep Stories (long-form bedtime audio often narrated by celebrities), breathing exercises, mindfulness courses, music for focus and sleep, and a Daily Calm session. The consumer Calm app is distributed through the iOS App Store and Google Play under a freemium subscription model. The company also operates two B2B products. Calm Business sells the consumer experience to employers as an employee wellness benefit, and Calm Health is a clinical mental health offering for health plans and large self-insured employers, with structured programs aligned to clinical needs. Both B2B products are powered by the Calm Partner API (auth.calm.com/v0), a small OAuth 2.0 client-credentials REST surface that partner systems use to provision, link, and cancel Calm subscriptions for their members or employees. Partners also integrate via SAML 2.0 IdP-initiated SSO and SFTP-uploaded eligibility files (CSV at sftp.ws.calm.com:/inbound/eligibility/). Calm publishes a handful of open-source utilities under github.com/calm — primarily iOS audio/video helpers (PersistentStreamPlayer, KenBurns) and React-Intl ESLint plugins — but there is no public consumer-facing developer API.
Calm publishes 2 APIs on the APIs.io network: Authentication API and Subscriptions API. Tagged areas include Mindfulness, Meditation, Sleep, Mental Health, and Wellness.
The Calm catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Calm’s developer surface includes authentication, developer portal, signup flow, pricing, documentation, support, engineering blog, and 21 more developer resources.
