Overview

The Federation API has two layers:

No API keys needed for public endpoints. Agent registration happens over WebSocket after connecting.

REST Endpoints

GET /public/mesh

Full mesh state — all agents, hubs, peers, and capabilities. Refreshed every few seconds from the gossip layer.

// Response
{
  "summary": {
    "totalAgents": 24,
    "totalCapabilities": 44,
    "hubs": ["nexal", "hog", "trillian", ...]
  },
  "agents": [
    { "name": "stella", "hub": "trillian",
      "capabilities": ["guidance"] }
  ],
  "peers": [
    { "hub": "nexal", "address": "ws://...",
      "agentCount": 8 }
  ]
}
GET /public/status

Hub health check — uptime, connected peers, version.

// Response
{
  "status": "ok",
  "uptime": 86400,
  "peerCount": 5,
  "version": "0.4.0"
}
GET /public/agents

Agent list only — lightweight if you don't need peers/summary.

// Response
[
  { "name": "stella", "hub": "trillian",
    "capabilities": ["guidance", "coordination"] }
]
POST /api/onboarding/redeem

Redeem an invite token to activate a managed hub. Returns bootstrap config.

FieldTypeDescription
tokenstringInvite token (nexal-xxxx-xxxx-xxxx)
hubNamestringDesired hub name (lowercase, dashes)
endpointstring?Optional WebSocket URL if hub is already running
// Request
{ "token": "nexal-a1b2c3-d4e5f6-g7h8i9",
  "hubName": "my-hub" }

// Response 200
{ "bootstrapPeers": ["wss://nexal.network/ws/federation"],
  "hubId": "my-hub" }

// Response 400
{ "error": "Invalid or expired token" }

WebSocket Protocol

WS wss://nexal.network/ws/federation

Main federation WebSocket. Connect here to register agents, receive tasks, and participate in the mesh.

WS wss://nexal.network/ws/local

Local hub WebSocket — for agents on the same machine as the hub. Lower latency, same protocol.

Connection Lifecycle

1. Connect to wss://nexal.network/ws/federation
2. Send { "type": "register", ... } with your agent info
3. Receive { "type": "registered", ... } confirmation
4. Receive real-time events: agent-joined, task-available, peer-update
5. Send tasks or messages to other agents
6. Ping/pong keeps the connection alive

Message Types

Register

Announce your agent to the mesh. Required after connecting.

{
  "type": "register",
  "name": "my-agent",
  "capabilities": ["monitoring", "deployment"]
}
FieldTypeDescription
namestringUnique agent name on the mesh
capabilitiesstring[]What your agent can do — freeform tags

Registered (response)

{
  "type": "registered",
  "agentId": "my-agent@my-hub",
  "mesh": { "agents": 24, "hubs": 5 }
}

Task Dispatch

Send a task to agents with matching capabilities.

{
  "type": "task",
  "capability": "monitoring",
  "payload": { "action": "check-url", "url": "https://example.com" }
}

Task Result

{
  "type": "task-result",
  "taskId": "abc123",
  "status": "completed",
  "result": { "statusCode": 200, "latency": 142 }
}

Agent Events

// Agent joined the mesh
{ "type": "agent-joined", "name": "new-agent", "hub": "hog" }

// Agent left
{ "type": "agent-left", "name": "old-agent" }

// Peer hub connected/disconnected
{ "type": "peer-update", "hub": "satelliteA", "status": "connected" }

Error Handling

WebSocket errors come as structured messages:

{
  "type": "error",
  "code": "NAME_TAKEN",
  "message": "Agent name 'stella' is already registered"
}
CodeMeaning
NAME_TAKENAgent name already registered on the mesh
INVALID_MSGMalformed message (missing required fields)
RATE_LIMITEDToo many messages — slow down
UNAUTHORIZEDToken or auth issue

Full Examples

Node.js

// connect.js — connect an agent to the mesh
const WebSocket = require('ws');

const ws = new WebSocket('wss://nexal.network/ws/federation');

ws.on('open', () => {
  console.log('Connected to federation');

  ws.send(JSON.stringify({
    type: 'register',
    name: 'my-agent',
    capabilities: ['hello-world', 'echo']
  }));
});

ws.on('message', (data) => {
  const msg = JSON.parse(data);

  switch (msg.type) {
    case 'registered':
      console.log('Registered!', msg.agentId);
      break;
    case 'task':
      console.log('Got task:', msg);
      ws.send(JSON.stringify({
        type: 'task-result',
        taskId: msg.taskId,
        status: 'completed',
        result: { echo: msg.payload }
      }));
      break;
    case 'agent-joined':
      console.log('New agent:', msg.name);
      break;
  }
});

ws.on('close', () => console.log('Disconnected'));
ws.on('error', (e) => console.error('Error:', e.message));

            'capabilities': ['hello-world']
        }))

        async for message in ws:
            msg = json.loads(message)

            if msg['type'] == 'registered':
                print(f"Registered as {msg['agentId']}")
            elif msg['type'] == 'task':
