for (const plate of data.plates) {
  console.log(`${plate.plate} — ${plate.conf.toFixed(1)}%`);
}

Python

import requests

print(f"Tempo: {data['processingTimeMs']}ms")
print(f"Créditos restantes: {data['creditsRemaining']}")

for plate in data['plates']:
    print(f"{plate['plate']} — {plate['conf']:.1f}%")
