Is is possible to retrieve the Tax Details from a customer via API?

[MattFroyer]

I need to get the customer Tax Details, specifically the VAT Number from the API. 

I'm currently using the REST admin API and neither the customer get requests or the order requests return this information. I searched the documentation and it doesn't mention how to get this information either.

Is there a way to get this information via API? (REST, GraphQL or Webhooks)?

I'm currently using the default version, not the Shopify B2B (Shopify Plus).

My objective is to use the API (REST/GRAPHQL) to get a customer and it's respective tax details.

This is the information i want to get from the Rest/GraphQL API, is this possible?

Again, this is relative to customers from my website, not the company information.
