Router addresses are automatically included in API responses. You don’t need to hardcode them in your application.

​
Getting Router Address Programmatically

​
Using the API

The router address is always included in API responses: 
curl -X POST "https://api.fibrous.finance/base/execute" \
  -H "Content-Type: application/json" \
  -d '{...}'
Response includes: 
{
  "to": "0x274602a953847d807231d2370072f5f4e4594b44", // Router address
  "calldata": "0x...",
  "value": "0"
}

​
Using the SDK

import { Router as FibrousRouter } from "fibrous-router-sdk";

const fibrous = new FibrousRouter();
const chains = fibrous.supportedChains;

// Get router address for a specific chain
const baseChain = chains.find(c => c.chain_id === 8453);
console.log("Base Router:", baseChain?.router_address);
