## Description

Returns `eligible`, `reasons[]`, `balance`, `charge`, `topUpRequired`, and the `registrantContacts[]` the caught domain may be registered to. Call this before `book_snapback_domain` whenever the customer has not already chosen a registrant.

## Query parameters

- `domain` — string. Optional: the dropping domain to price this for, e.g. example.se.
