# BRL/USDC FX API for a Payments Lead at a Cross-Border Fintech: Taking Engineering Off FX Maintenance in Brazil

> How the Crown FX BRL/USDC API takes a cross-border fintech's engineers off maintaining its own FX.

Maintaining self-run FX occupies engineers who could be on the main product. With the [Crown FX](https://crown-brlv.com) API, BRL and USDC settlement, liquidity and reporting stay with Crown, and the fintech's team handles the integration.

**Moves to Crown:** real-time settlement over Pix and stablecoins; liquidity for operations; monthly consolidation of Central Bank reporting.

**Stays with the fintech:** the integration, the product and the user relationship, with sub-accounts and its own brand. The API offers quotes, orders, withdrawals, balances, transaction history and event webhooks, documented at [docs.crown-brlv.com](https://docs.crown-brlv.com).

**Scaling.** FX-as-a-Service lets FX scale without building infrastructure; confirm operating limits with Crown. The API authenticates with API keys and JWT tokens, and an OpenAPI specification is published.
