      outputFormat: 'webp'   // 'png' | 'webp' | 'svg'
    })

const blob = await response.blob();
const url  = URL.createObjectURL(blob);
document.querySelector('#qr-img').src = url;
import requests

response = requests.post(
    'https://qrrapido.site/api/v1/QRManager/generate',
    headers={
        'X-API-Key': 'qr_SuaChaveAqui',
        'Content-Type': 'application/json'
