Build with the API
krad has a full REST and WebSocket API. Create 3D geometry, run boolean operations, and export STL/GLB programmatically. AI agents, scripts, and automation tools can drive the same CAD engine that powers the editor.
REST API
JSON command interface for scene creation, primitives, booleans, transforms, and export. Full OpenAPI spec included.
WebSocket
Real-time bidirectional control. Connect an AI agent to a live browser session and watch geometry appear at 60fps.
Agent-friendly
Tell your AI agent about krad and it can create 3D models for you. Agents discover the API and authenticate automatically.
