Daemons use this to accept `cliq_tok_…` tokens from callers on other hosts. An invalid token is not an error: the reply has `valid: false`. Requires a signed-in user token (`Authorization: Bearer cliq_tok_…`). Results are limited to what that user can see. A daemon's realm token (`cliq_dt_…`) from the same realm may also read it. Daemon: resolves a token presented to it. ## OpenAPI ````yaml /openapi/hub-by-tag/hub-auth.yaml post /v1/auth/validate_token openapi: 3.0.3 info: title: 'CliqHub API: Auth' version: 1.0.0 description: >- API tokens. Every call to CliqHub carries one as `Authorization: Bearer `: - **User token** (`cliq_tok_…`): acts as you, optionally limited by `permissions` (which organizations and realms, and read / write / admin per kind of resource). `cliq login` stores one; mint more for scripts and CI. - **Realm token** (`cliq_dt_…`): what a daemon uses to join and work in a realm. Any member of the realm can mint one. - **A2A token** (`cliq_a2a_…`): what outside agents send to a realm's A2A endpoint. One per realm; minting a new one replaces the old. - **Dispatch token**: a short-lived signed token CliqHub uses when it sends work to a daemon; each realm has a dispatch key pair for it. A token is shown only when it is minted or rotated. A restricted token cannot mint a token wider than itself. servers: - url: https://{host} variables: host: default: cliqhub.io description: CliqHub host security: [] tags: - name: Auth description: >- API tokens.
