Parameter Required Description
apikey Yes Access code that authorizes your request for data from Rovi.
genreids Yes ID of the genre, subgenre, or style. You can get a complete list of IDs from Descriptor/MusicGenres. And you can pick up IDs from responses to the following calls:

To specify multiple IDs, use a comma-separated list, like this: genreids=MA0000002467,MA0000002944.

sig Yes A calculated, 32-hex-digit authorization code. To perform the calculation, execute the MD5 function on the concatenation of the following three ASCII strings:
  • Your API key.
  • The secret key you received with your API key.
  • The Unix time. Unix time is a timestamp supported in most development environments, and is generally defined as the number of seconds since January 1, 1970 00:00:00 GMT.

Express the alpha hex digits as lower case.

Perform the calculation at the time of each request to be sure it's within a five-minute window of the server time. If you're testing the call in a browser, use our online signature generator to perform the calculation.

count No Number of items to be returned. The default is zero, which returns all items after the offset.
country No Country the language parameter applies to. The current release of the API supports only US.
format No Format of the returned data: json or xml. The default is JSON.
language No Language of the response data. This request supports only en (English).
offset No Number of items at the start of the available data to skip. The default is zero.

Use count and offset to paginate the data that is available to be returned.
