Single-import, @Published license state, offline-ready Ed25519 lease verification. Stable
SDKs and platforms
Keylight ships a first-party Swift SDK today. The HTTP API is stable and public, so anything that can sign requests can integrate in the meantime — first-party SDKs for the other major platforms are on the way.

Anything else: use the REST API
Section titled “Anything else: use the REST API”The Keylight backend is a thin, well-documented HTTP service. If your platform isn’t in the list above, you can still ship licensing today by calling the API directly:
- Every request to
/{tenantId}/activate,/{tenantId}/validate, and/{tenantId}/deactivateis a plain JSON POST. - Authenticate with the
X-Keylight-SDK-Keyheader (one per tenant, rotatable from the dashboard). - Successful responses include an Ed25519-signed lease you can verify locally with the tenant’s public key — no need for a network round-trip on every app launch.
The signature format and lease schema are documented in Offline leases, so a 60-line implementation is enough for most platforms.
