Parameter | Required | Description |
apikey | Yes | Access code that authorizes your request for data from Rovi. |
genreids | Yes | Subgenre ID from the list at the top of this page.
To specify multiple IDs, use a comma-separated list, like this: genreids=MA0000004509,MA0000004499. |
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:

- 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. |
