REST API Overview
The AgentVault backend exposes a RESTful API athttps://api.agentvault.chat. All routes are prefixed with /api/v1/ and return JSON responses.
Zero-knowledge principle: The API transports only ciphertext. Message bodies are opaque BYTEA blobs encrypted client-side using MLS (primary) or Double Ratchet (fallback). The server never decrypts or inspects message content.

Real-time bidirectional messaging.
The WebSocket accepts a Clerk JWT, Device JWT, or API Key as the
token query parameter. Once connected, messages are exchanged as JSON frames:
ping events every 30 seconds. Clients must respond with pong to maintain the connection. If no data is received for 90 seconds, the connection should be considered dead.
