demo.st Document API
Optional JSON document store at api.demo.st - collections and records scoped to a site API key - that a static site published on demo.st can call from the browser. The homepage says to embed the key for https://api.demo.st/v1 as Authorization: Bearer dk_... (it requires a reserved subdomain); the API root advertises /v1/:collection (Bearer dk_... or X-Demo-Key) and /health. demo.st publishes no OpenAPI or other machine-readable contract for it.
