We're always looking to improve our API, so we're happy to take a look at adding a field you need! Our API is built to avoid data sparsity, so if the field is not widely supported across platforms, it's not something we'll be able to add.
We never want to be a blocker for any of our customers and realize some platforms may have specific fields that are important to our users, which is why we support Supplemental Data. This allows our customers to hit integration APIs directly to get specific data needs for their use case!
