  • Registered applications can exceed the daily request limit.
  • Registered users receive advance notice of planned changes to the API.
  • API usage statistics for the key are available on request.

More information about the API is available in the online documentation at:

  1. Fill in the online registration form and submit to RoMEO.
  2. RoMEO will confirm receipt by sending you an automatic email message.
  3. Click on the link in the email message to receive your API Key immediately .
