REST API Reference
All endpoints are served by the management WebUI Flask application bound to 127.0.0.1:9090, proxied through nginx with SSL termination and HTTP basic authentication. Requests target the management domain (e.g., https://wall.lan/api/...).
Every request and response uses Content-Type: application/json.
