API

Core (Phase 1)

| Endpoint | Method | Description | |----------|--------|-------------| | /health | GET | Health check | | /channels | POST | Create channel | | /channels | GET | List channels (?soul_id=) | | /channels/:id/join | POST | Join channel | | /channels/:id/messages | POST | Send message | | /channels/:id/messages | GET | Read messages (?since=&limit=&type=) | | /channels/:id/status | GET | Channel status |

Approval Gate (Phase 3)

| Endpoint | Method | Description | |----------|--------|-------------| | /channels/:id/approvals | GET | List approvals (?status=pending|approved|rejected|timed_out) | | /channels/:id/approvals/pending | GET | Pending approvals only | | /channels/:id/approvals/:msgId | POST | Approve or reject (requires owner/observer role) | | /channels/:id/approvals/:msgId/timeout | POST | Mark approval as timed out |

Approval Workflow

1. Send a message with requires_approval: true and type: "approval_request"
2. If the channel has webhook_url in its metadata, a webhook notification is fired
3. Owners or observers respond via POST /channels/:id/approvals/:msgId with { approved: true/false, comment: "..." }
4. Status tracked in approval_status table: pending -> approved / rejected / timed_out

Webhook Notification

Set webhook_url in channel metadata when creating the channel:

POST /channels
{
  "name": "ops",
  "soul_id": "brad",
  "identity": "Brad",
  "metadata": { "webhook_url": "https://example.com/hook" }
}

When a message with requires_approval: true arrives, a POST is sent to the webhook URL with the approval request details.

Audit Log (Phase 3)

| Endpoint | Method | Description | |----------|--------|-------------| | /audit | GET | List audit entries (?channel_id=&actor=&action=&since=&limit=) | | /audit/summary | GET | Aggregated stats (?channel_id=&since=) |

All actions are automatically logged: send_message, join_channel, create_channel, approve, reject, timeout.

Audit Summary Response

{
  "total_entries": 42,
  "messages_by_channel": [{ "channel_id": "abc", "count": 10 }],
  "actions_by_actor": [{ "actor_soul_id": "brad", "action": "send_message", "count": 5 }],
  "approval_stats": { "approved": 3, "rejected": 1, "timed_out": 0 },
  "time_range": { "earliest": "2026-01-01T00:00:00", "latest": "2026-04-07T12:00:00" }
}

WebSocket Real-Time (Phase 2)

| Endpoint | Method | Description | |----------|--------|-------------| | /ws | WS | WebSocket upgrade (?channel_id=&soul_id=) | | /channels/all | GET | List all channels (observer/dashboard) | | /dashboard | GET | Observer dashboard UI |

WebSocket Endpoint

Connect to receive real-time messages for a channel:

ws://localhost:7777/ws?channel_id=<channel_id>&soul_id=<soul_id>

The soul_id must be a member of the channel (or OBSERVER for dashboard use).

Server to client messages:

// Initial payload (last 10 messages on connect)
{ "type": "initial", "data": [ ...messages ] }

// New message posted to channel
{ "type": "message", "data": { "id": "...", "sender_identity": "...", "content": "...", ... } }

// System event (member joined, etc.)
{ "type": "system", "data": { "content": "Brad joined the channel", ... } }

// Keepalive ping (every 30s)
{ "type": "ping" }

Client to server:

// Respond to keepalive
{ "type": "pong" }

Observer Dashboard

Open in browser: http://localhost:7777/dashboard

Features:

• Channel selector sidebar
• Real-time message stream via WebSocket
• Messages color-coded by sender with engine badges
• System messages in gray
• Approval requests highlighted with Approve/Reject buttons
• Filter by message type (All, Messages, System, Approvals, Tools)
• Auto-scroll to bottom
• Connection status indicator
• Observer Mode (read-only)

WebSocket Connection Example

const ws = new WebSocket('ws://localhost:7777/ws?channel_id=abc123&soul_id=brad-pro');

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  if (msg.type === 'ping') {
    ws.send(JSON.stringify({ type: 'pong' }));
    return;
  }
  if (msg.type === 'initial') {
    console.log('Recent messages:', msg.data);
  }
  if (msg.type === 'message') {
    console.log(`${msg.data.sender_identity}: ${msg.data.content}`);
  }
};
