Calm

Calm is a leading consumer mental-wellness company whose app offers guided meditations, Sleep Stories, breathing programs, mindfulness masterclasses, and soundscapes. Beyond the direct-to-consumer app, Calm sells two B2B products: Calm Business, which delivers the Calm experience to employers as an employee wellness benefit, and Calm Health, a clinical mental-health offering for health plans and large self-insured employers. Both are powered by the Calm Partner API, an OAuth 2.0 client-credentials REST surface that partner HR and benefits systems use to provision, link, and cancel Calm subscriptions for their members, alongside SAML 2.0 IdP-initiated SSO and SFTP eligibility-file uploads. Calm is a portfolio company of Lightspeed Venture Partners.

Calm publishes 2 APIs on the APIs.io network: Authentication API and Subscriptions API. Tagged areas include Company, Mental Health, Wellness, Meditation, and Mindfulness.

The Calm catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Calm’s developer surface includes documentation, API reference, getting-started guide, support, pricing, authentication, sandbox, and 68 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/calm: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
