const base = "https://api.carbium.io";
const headers = { "Authorization": `Bearer ${key}` };

const quote = await fetch(`${base}/v1/quote?in=USDC&out=SOL&amount=25`, { headers }).then(r => r.json());
const tx = await fetch(`${base}/v1/swap`, { method: "POST", headers: { ...headers, "Content-Type":"application/json" }, body: JSON.stringify({ route: quote.route, slippageBps: 50 }) }).then(r => r.json());
// send tx.signed to the network via rpc.carbium.io

# Simple RPC call
import os, requests, json
RPC = "https://rpc.carbium.io"
