  title: Unkey analytics liveness API
  description: 'Unkey is an open-source developer platform for API key management, authentication, and rate limiting. This is an API Evangelist modeling of Unkey''s RPC-style REST API, grounded in Unkey''s own published OpenAPI. All operations use POST and are grouped into service namespaces (keys, apis, ratelimit, identities, permissions, analytics, deploy, liveness). The stable v2 API is served from https://api.unkey.com; the legacy v1 API is served from https://api.unkey.dev with /v1/* paths.


    Authentication uses HTTP Bearer authentication with a root key: `Authorization: Bearer unkey_xxxxxxxxxxx`. Most endpoints require specific permissions on the root key. Responses use a consistent envelope with a `meta.requestId`, a `data` object (or array plus `pagination` on list endpoints), and a structured `error` object on failures.'
