# 1. Query Cainiao Smart Logistics origin waybill (extracts final-mile barcode in .message):
curl "https://api.lastscanned.com/v1/track/LP00639182736454" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

# 2. Query the extracted PostNL barcode:
curl "https://api.lastscanned.com/v1/track/3SCNL9482019482" \
  -H "Authorization: Bearer lsk_live_YOUR_API_KEY"

const headers = { Authorization: `Bearer ${process.env.LASTSCANNED_API_KEY}` };
const originRes = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(number)}`, { headers });
const originPkg = await originRes.json();

// Extract secondary barcode from top-level message ("3SCNL9482019482")
const handoff = originPkg.message?.match(/^Handed to (.+?) as ([A-Z0-9-]+)$/i);
if (handoff) {
  const [, , lastMileNumber] = handoff;
  const destRes = await fetch(`https://api.lastscanned.com/v1/track/${encodeURIComponent(lastMileNumber)}`, { headers });
  const destPkg = await destRes.json();
}
