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.

format No Format of the returned data: json or xml. The default is JSON.
