Koko

Koko is a 501(c)(3) nonprofit that makes free, evidence-based mental health support available to young people where they already are — inside the online platforms they use. Koko says it has reached more than 6 million users across 199 countries. Its model is detection plus direction: a keyword and AI engine identifies high-risk posts and searches on partner platforms, and matched users are routed to free crisis helplines and self-guided mini-courses covering mood regulation, body image and self-harm. Koko ships this as a developer-facing Suicide Prevention Toolkit built on two APIs — the credential-gated Koko Keywords API, wrapped by a native Rust client with Python, Ruby, Go and PHP bindings, and the public Crisis Helplines API, which returns crisis helpline contact data by country. Koko has been deployed by TikTok, Pinterest, Giphy, Snapchat, Tumblr, Bluesky, WhatsApp and Discord, and its work is backed by eight peer-reviewed publications including three randomized controlled trials.

Koko publishes 2 APIs on the APIs.io network: Countries API and Helplines API. Tagged areas include Company, Mental Health, Crisis Support, Suicide Prevention, and Trust and Safety.

Koko’s developer surface includes documentation, API reference, getting-started guide, signup flow, support, changelog, authentication, and 20 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.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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