# BRL/USDC FX API for the CEO of a Cross-Border Fintech: Taking Engineering Off FX Infrastructure Maintenance in Brazil

> How the Crown FX BRL/USDC API takes engineers off in-house FX maintenance so the team can stay on the product.

Running an in-house FX stack ties up engineers who could be on the main product. With the [Crown FX](https://crown-brlv.com) API, BRL and USDC settlement, liquidity and regulatory reporting move to Crown, and the fintech's team stays on the product and the user experience.

**What leaves the fintech's maintenance list**

- Instant BRL and USDC settlement over Pix and stablecoins.
- Liquidity for the trades.
- Monthly consolidation of reporting to the Central Bank, in the required format, end-user transactions included.

**What stays in-house.** API integration, product design and the customer relationship. The fintech can open sub-accounts per customer and operate under its own brand; the documented API ([docs.crown-brlv.com](https://docs.crown-brlv.com)) covers accounts, wallets, quotes, orders, withdrawals and event webhooks.

**Scaling.** The FX-as-a-Service model lets FX volume grow without building infrastructure. Operating limits and volumes should be agreed with Crown.
