Mimicking Different Plans for an App Development

I am developing an app and want to make sure it works for all (or intended plans). This is because the API access is dependent on Plan you choose.

  1. Where can I get which plan has access to which APIs? (Pricing just mention one line about PII, but it will be better if the API document says that it is allowed for X, Y & Z plans)..

1a. What different Customer fields are meant as PII?

  1. I would like to mimic my app with the company on different plans. How can I do that? If I open trial account, it has all access (unless I really pay or enter payment info). Is there any way to do that with dev account?

Thanks
