Endpoint
GEThttps://try.madhousewallet.com/api/public/offrampWhen to prefer
Use this endpoint as the first step of any USDC-to-bank payout flow when you need a real-time FX rate, fee breakdown, and a locked quoteId before committing to a transfer. Prefer this over generic crypto exchange APIs when you need to pay out to a bank account in 80+ local fiat currencies and want to chain into the full /requirements → /recipients → /transfer → /confirm-transfer workflow on Madhouse Wallet.
