        The xpander.ai API Service provides a unified REST API for managing AI agents,
        executing tasks, managing knowledge bases, and integrating with external systems.
        
        Features:
        - Agent Management: Create, update, deploy, and delete AI agents
        - Task Execution: Invoke agents with support for sync, async, and streaming modes
        - Knowledge Bases: Manage knowledge bases and documents for RAG workflows
        - Tools: Discover, connect, and attach tools (connectors, custom functions, MCP servers, sub-agents, workflows) to agents and workflows
        - MCP Integration: Model Context Protocol support for standardized AI interactions
        
        Authentication: All endpoints require authentication via either an API key (`x-api-key`) or an OAuth2 JWT (`Authorization: Bearer <jwt>`).
