# Treasurer Paying Overseas Suppliers: Stablecoin FX Through an API, Settled in Minutes in Brazil

> How a treasury integrates the Crown FX API to settle supplier payments abroad in minutes, with webhooks and transaction history.

Through the API, [Crown FX](https://crown-brlv.com) executes FX instantly and settles in a few minutes (D+0), and the treasury follows every step by webhook and transaction history.

**What the treasury integrates.** Quotes and conversion orders, reais deposits by Pix QR code, transfers among EVM wallets, withdrawals by Pix, TED or token, balances and the full transaction history. Webhooks cover order completed, transfer completed and withdrawal completed, among other events. Documentation: [docs.crown-brlv.com](https://docs.crown-brlv.com).

Each call authenticates with API keys and JWT tokens, and webhooks plus history let the treasury reconcile every payment.

**Timing.** Minutes, 24/7; D+1 or D+2 if preferred. The documented ceiling for payments is US$ 100,000 per operation.

An OpenAPI specification is published alongside the documentation.
