Its status becomes `online`. The daemon must be a member of the token's realm. Daemon only: requires the daemon's realm token (`Authorization: Bearer cliq_dt_…`). User tokens are refused. Daemon must be in the token realm. ## OpenAPI ````yaml /openapi/hub-by-tag/hub-daemons.yaml post /v1/daemons/heartbeat openapi: 3.0.3 info: title: 'CliqHub API: Daemons' version: 1.0.0 description: >- Daemons (`cliqd`) connected to CliqHub.
