Overview

The Gateway router creates a unified API surface that merges local and remote agent/team/workflow endpoints. It proxies requests to remote servers and includes health checking.

​
Quick Start

import { createAgentRouter } from "@radaros/transport";
import { createGatewayRouter } from "@radaros/transport";
import express from "express";

const app = express();
app.use(express.json());

// Local agents are served normally
app.use("/api", createAgentRouter({ cors: true }));

// Gateway routes to remote endpoints
app.use("/api", createGatewayRouter({
  remotes: [
    {
      baseUrl: "https://us-east.api.example.com",
      agents: ["analyst", "researcher"],
      teams: ["research-team"],
    },
    {
      baseUrl: "https://eu-west.api.example.com",
      agents: ["translator"],
      workflows: ["translation-pipeline"],
      headers: { Authorization: "Bearer eu-token" },
    },
  ],
  healthCheckIntervalMs: 30_000,
}));

app.listen(3000);

​
Health Monitoring

GET /gateway/health
Returns: 
{
  "remotes": {
    "https://us-east.api.example.com": true,
    "https://eu-west.api.example.com": false
  }
}

SSE Streaming

The gateway transparently proxies SSE streams — POST /agents/:name/stream calls are forwarded with event stream passthrough.
