Lingokids

Lingokids is a children's edutainment platform operated by Monkimun Inc. (Wilmington, Delaware) and Monkimun Labs S.L. (Madrid, Spain), delivering an ad-free "Playlearning" experience of games, animated shows, podcasts and sing-alongs for children aged two to eight. The mobile apps (iOS, Android, Amazon) and web app have been downloaded more than 200 million times. The curriculum is built by parents and educators and covers English-language learning alongside broader academic and life skills. Lingokids is audited and certified by the kidSAFE Seal Program (COPPA+), operates a COPPA-compliant configuration for child data, and honours GDPR rights for EU residents.

Regulatory Posture applies to this provider. Its tags matched the Education & Research 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 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.

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