  headers: {
    'X-API-KEY': 'YOUR_API_KEY'
  }
}
try {
  const response = await axios.request(config)
  console.log(response)
} catch (error) {
  // Handle error
  console.log(error)
}

import requests
try:
  url = 'https://api.mintly.uk/bankAccount/v1/sortcode/XXXXXX/account/YYYYYYYY'
  headers = { 'X-API-KEY': 'YOUR_API_KEY' }
  r = requests.get(url, headers=headers, timeout=0.1)
  r.raise_for_status()
