Apple CloudKit
Apple CloudKit is the cloud backend for iOS, iPadOS, macOS, tvOS, watchOS, visionOS, and the web. CloudKit Web Services is the public REST surface that lets non-Apple-platform clients (web apps, servers) read and write data into a CloudKit container's public, private, or shared database. The web service is hosted at api.apple-cloudkit.com and accepts either an API token (for end-user-authenticated access) or a server-to- server ECDSA key for backend access. Operations cover records, zones, subscriptions, assets, users, and database changes.
Apple CloudKit publishes 10 API contracts indexed on the APIs.io network, including Assets API, Changes API, Records API, and 7 more. Tagged areas include Apple, Cloud Storage, CloudKit, Database, and iCloud.
The Apple CloudKit catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Apple CloudKit’s developer surface includes authentication, documentation, developer console, sandbox, changelog, CLI, API reference, and 33 more developer resources.
Kin Score
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 |
|---|---|---|---|---|
| Apple Accessory & Device Ecosystem (MFi, Matter, Apple partners) | undeclared | - | - | - |
| Mobile SDK Publishers (Play SDK Index, CocoaPods, ADA certification) | undeclared | - | - | - |
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.
