Adapty

Adapty is a mobile in-app subscription platform for iOS, Android, Flutter, React Native, and Unity apps. Its core is a client SDK for paywalls, A/B testing, remote config, and server-side receipt validation, backed by a supporting Server-Side REST API for programmatically managing profiles, purchases and transactions, access levels (entitlements), and paywalls, plus webhooks and integrations for streaming subscription events to downstream analytics and marketing tools.

Adapty publishes 6 API contracts indexed on the APIs.io network, including Access Levels API, Integrations API, Paywalls API, and 3 more. Tagged areas include Mobile, Subscription, In-App Purchases, Paywalls, and Analytics.

Adapty’s developer surface includes engineering blog, authentication, documentation, and 11 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/adapty: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Stripe App Marketplace and Partner Ecosystem (builders on Stripe)	undeclared	-	-	1
Mobile SDK Publishers (Play SDK Index, CocoaPods, ADA certification)	undeclared	-	-	1
Official SDKs on Packagist, pub.dev and Hex	undeclared	-	-	1

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
