A minimal Node script that calls GET /quote?mode=DELTA and prints the indicative destAmount, deadline, and hmac from the returned delta payload. No SDK — just fetch.

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

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

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

console.log('destAmount:', delta.destAmount);
console.log('deadline:  ', delta.deadline);
console.log('hmac:      ', delta.hmac);

​
Run it

pnpm tsx src/quote.ts
You should see the indicative destAmount (USDC, 6 decimals), the order deadline (unix seconds), and the hmac you must pass through verbatim when building the order.

​
Next: build, sign, submit

Pass the whole delta object into POST /delta/orders/build (as the price field) to get EIP-712 typed data. Sign it with an ERC-2098 compact signature, then POST /delta/orders with the order + signature. See Delta → How it works.
Pass the delta payload verbatim to /delta/orders/build. Mutating any field (including hmac) will cause the build call to reject.
