    urlTld: 'com'
}

The fine print

  • For parsing permalinks please use the async method, since permalinks are basically HTTP 301 redirects.
  • You may also pass raw ASIN/ISBN numbers as arguments.
  • No exception is thrown on an invalid argument. The resulting object would simply contain undefineds.
  • Heavily influenced by amazon-helpers.
