  description: >-
    Unified API for moving money between crypto and fiat. Three ways to move
    money: Transactions (instant, wallet or card funded, including Cash-In for
    in-person cash deposits), Deposit Addresses (reusable crypto deposit
    configurations), and Virtual Accounts (dedicated bank accounts that
    auto-convert fiat to crypto). Standard transactions follow a two-step flow:
    create a Quote (pricing), then create a Transaction (execution). Cash-in
    codes generate a one-time deposit code for in-person cash deposits at retail
    locations.
