Read the context of your token

Introspects the caller behind the request. Any caller can read it — a browser session, an API key, a machine credential, a Space key, a partner token, or no credential at all — and every answer carries the Spacefast agent instructions as Markdown, filtered by scopes and budgeted for the consumer. An authenticated caller also gets a credential block naming what kind of token it is and what it is bound to, and a user-owned interactive grant gets a capabilities map of the operations its scopes allow.
