Convert: Buy & Sell Stablecoins

Use your VA fiat balance to buy USDC/USDT, or sell stablecoins back to fiat with payout to a registered bank account. The flow is a two-step pattern:

Get quote (price + fees) → returns a quote_id

Create order (confirm buy / sell / transfer) using that quote_id

One API set for all conversions

The quote & order APIs are shared across transfer, buy, and sell — distinguish by type when placing the order. For sell orders, you must register a payout bank account first (see Section 3).

Prerequisite

VA fiat balance comes from local fiat collection. See Fiat Vitual Account for how to provision a VA and receive funds.
