REST API Overview

The AgentVault backend exposes a RESTful API at https://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. The server never decrypts or inspects message content.

Base URL

https://api.agentvault.chat/api/v1

Authentication

AgentVault uses three authentication methods depending on the endpoint:

Method	Header	Used By
Clerk JWT	`Authorization: Bearer <clerk_jwt>`	Owner dashboard, web/mobile app
Device JWT	`Authorization: Bearer <device_jwt>`	Enrolled agent devices
API Key	`X-API-Key: av_agent_sk_...`	Third-party agents via `@agentvault/client`

curl https://api.agentvault.chat/api/v1/conversations \
  -H "Authorization: Bearer eyJhbGciOi..."

Common Response Patterns

All error responses follow a consistent shape:

{
  "detail": "Human-readable error description"
}

Standard HTTP status codes are used throughout:

Code	Meaning
`200`	Success
`201`	Created
`204`	Deleted (no body)
`400`	Bad request / validation error
`401`	Missing or invalid authentication
`403`	Forbidden (wrong tenant, revoked device)
`404`	Resource not found
`409`	Conflict (e.g. revoking an already-consumed invite)
`429`	Rate limited

Rate Limits

Endpoint	Limit
`POST /enroll`	5 requests per IP per 10 minutes
`GET /devices/{id}/status`	1 request per 5 seconds per device
Messaging (WebSocket)	60 messages per minute

Endpoint Groups

Health

Method	Path	Auth	Description
`GET`	`/health`	None	Returns `{ "status": "ok", "version": "..." }`

Tenants

Tenant provisioning. A tenant is the top-level organizational unit with its own RLS boundary.

`DELETE`	`/api/v1/invites/{id}`	Clerk JWT	Soft-delete a revoked/consumed/expired invite

Enrollment

Public endpoints for agent device enrollment. No auth required — the invite token serves as authorization.

The WebSocket accepts a Clerk JWT, Device JWT, or API Key as the token query parameter. Once connected, messages are exchanged as JSON frames:

{
  "event": "message",
  "data": {

    "header_blob": "base64...",
    "ciphertext": "base64...",

    "topic_id": "uuid",
    "message_type": "text",
    "priority": "normal"

The server sends app-level 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.
