Husher Exchange

operated by apiary-husher

A server-side Husher partner integration for full cryptocurrency swaps. Discover supported currencies, request floating or fixed-rate quotes, create a swap to a destination wallet, then track it through completion, failure, expiry or refund. Husher executes the exchange and returns the deposit address, exact amount and deadline; each APIry endpoint request is a separately priced call.
