The catalog/availability endpoint lists a price that does not include VAT. For hobby sellers no VAT is charged to the customer. But for professional sellers VAT is charged at checkout.
The problem: the API does not indicate whether VAT will be charged at checkout and how much. This hinders determining which sellers has the best price.
Suggestion: add an extra field for every lot returned in the catalog/availability endpoint. I see three options:
- A field indicating the price of the item including VAT. For hobby sellers this would be the same as the 'price' field.
- A field indicating the VAT that will be added.
- A field indicating the VAT percentage that will be charged.
