SpacetimeDB HTTP API is published by [Clockwork Labs](https://apis.io/providers/clockwork-labs/) on the [APIs.io](https://apis.io/) network. Tagged areas include Database, Real-Time, WebSocket, and Identity. The published artifact set on APIs.io includes API documentation, an API reference, and authentication docs.

The SpacetimeDB HTTP API lets clients and tools interact with SpacetimeDB databases: publish and delete database modules, manage database names, retrieve schema and logs, invoke reducers, run SQL queries, open real-time subscription WebSockets, and create/verify Spacetime identities and JWT tokens. Authentication is a Bearer JWT (SpacetimeAuth/OIDC, or an anonymously generated identity token). Base host is the hosted SpacetimeDB Cloud (Maincloud); the same API is served by any self-hosted `spacetime start` instance.
