Capy Inc.

Capy Inc. operates Lemin Captcha, a gamified bot-prevention and CAPTCHA service that replaces traditional image-selection challenges with playful, brandable puzzle games.

Developers embed a client-side widget (available as first-party React, Angular, and Vue components on npm), then verify the visitor's encrypted answer server-side against the Lemin verification API using their account private key. Capy Inc. is a 500 Global portfolio company.

Capy Inc. publishes 1 API on the APIs.io network: Verification API. Tagged areas include Company, Security, CAPTCHA, Bot Detection, and Bot Prevention.

Capy Inc.’s developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, authentication, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/capy-inc: open an issue to ask a question, or submit a pull request to add artifacts.
