About RateFlow
A developer-first currency exchange rate API built for reliability, speed, and simplicity.
Our mission
RateFlow was built to provide developers with a reliable, fast, and affordable API for currency exchange rate data. We believe that access to current financial data should be simple — clear endpoints, clean JSON responses, and straightforward integration.
Our REST API is clean and familiar, so integration is straightforward — it works with any HTTP client. Just configure your base URL and API key to get started.
Built on proven technology
Laravel + Livewire
Built on Laravel — the most popular PHP framework — with Livewire for reactive UI components. Proven, battle-tested, and maintainable.
Redis Caching
Exchange rates are cached in Redis so common API requests can be served quickly without calling upstream providers on every request.
Multiple Rate Sources
Rates can be fetched from configured central-bank and provider sources, with priority-based conflict resolution for overlapping coverage.
Domain-Driven Design
The codebase follows DDD principles with clear bounded contexts — separating API, Billing, User, and Rate domains — ensuring maintainability as the product grows.
