How do I track Yanwen and YunExpress numbers with an API?

curl "https://api.lastscanned.com/v1/track/UL494089685YP" \
  -H "Authorization: Bearer lsk_live_YOUR_KEY"

curl "https://api.lastscanned.com/v1/track/YT2621200705470145" \
  -H "Authorization: Bearer lsk_live_YOUR_KEY"

const res = await fetch("https://api.lastscanned.com/v1/track/UL494089685YP", {
  headers: { Authorization: `Bearer ${process.env.LASTSCANNED_KEY}` },
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
console.log(await res.json());

import os
import requests

r = requests.get(
    "https://api.lastscanned.com/v1/track/YT2621200705470145",
    headers={"Authorization": f"Bearer {os.environ['LASTSCANNED_KEY']}"},
    timeout=60,
)
r.raise_for_status()
print(r.json())
