# BRL/USDC FX API for the CEO of a Cross-Border Fintech: Not Spending Months Building FX Infrastructure in Brazil

> Why integrate a BRL/USDC FX API instead of building your own FX infrastructure: what an in-house rail demands and what Crown FX supplies.

An in-house FX rail demands liquidity, integrations, regulatory compliance and a dedicated team, which adds up to months of work away from the core product. The [Crown FX](https://crown-brlv.com) API settles BRL and USDC instantly, opens a sub-account per customer and lets the fintech operate under its own brand.

**What the CEO does not have to build**

1. Liquidity, which Crown FX supplies.
2. Payment integrations: Pix on the real side, USDC or USDT on the dollar side, already connected.
3. Compliance: Crown handles the regulatory complexity, including mandatory Central Bank reporting of end-user transactions.
4. A standing team to keep the FX rail running.

**What integration involves.** The API uses API keys and JWT tokens; documentation and an OpenAPI specification are at [docs.crown-brlv.com](https://docs.crown-brlv.com). Crown states the product is already in production with real customers for this use case; no end customers are publicly named.

**How to decide.** Set the integration timeline and effort against an in-house build, and have Crown confirm the schedule in writing.
