const params = new URLSearchParams({
  srcToken:     '0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE', // ETH
  destToken:    '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48', // USDC
  amount:       '1000000000000000000', // 1 ETH
  srcDecimals:  '18',
  destDecimals: '6',
  side:         'SELL',
  network:      '1',
  userAddress:  '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045',
  partner:      'my-app-name',
});

const res = await fetch(`https://api.velora.xyz/prices?${params}`);

if (!res.ok) {
  throw new Error(`HTTP ${res.status}: ${await res.text()}`);
}

const { priceRoute } = await res.json();

console.log('destAmount:', priceRoute.destAmount);
console.log('gasCostUSD:', priceRoute.gasCostUSD);

​
Run it

pnpm tsx src/quote.ts
You should see the quoted destAmount (USDC, 6 decimals) and gasCostUSD printed.

​
Next: build the transaction

Feed the priceRoute into POST /transactions/:network to get ready-to-broadcast calldata. See Market API → How it works.
