  title: Blaxel Control Plane Agents Functions API
  description: Representative specification of the Blaxel (formerly Beamlit) control plane REST API. The control plane manages agents, MCP/function servers, models, sandboxes, jobs, policies, integrations, and workspaces. Authenticate with a Bearer API key (Authorization or X-Blaxel-Authorization header) or an OAuth 2.0 short-lived JWT. Requests may include a Blaxel-Version header (YYYY-MM-DD) and, for multi-workspace accounts, an X-Blaxel-Workspace header.
