I would like to get list price from Products-PriceBooks related object.

I've checked the getRelatedRecords method on API Methods documentation, but I can't see the description for the case of reference-relationship. There are some examples for parent-child relationship as below link:

I'd tried the above for Products-PriceBooks, but it doesn't work.

I would appreciate it if someone show me examples.

Thanks,
