Exchange Rate Data API
"Exchangerateapi.net is a developer-focused service that supplies up-to-date and historical foreign-exchange data through a clean REST interface. Responses are returned as JSON over HTTPS, CORS is enabled out of the box, and access is secured with simple API-key authentication.
Applications can request the latest market rates, run on-the-fly currency conversions, and pull time-series datasets for reporting and analytics.
The platform is optimized for quick integration and dependable uptime, making it a practical fit for e-commerce pricing, invoicing and accounting tools, finance and travel apps, dashboards, and automated back-office workflows.
The application is built with Laravel in PHP and uses PostgreSQL for primary storage with Redis providing aggressive caching to keep latency low. Authentication relies on per-key tokens with configurable quotas. Data is sourced from reputable central-bank and market feeds. Historical imports and live updates are handled by queued workers and scheduled jobs to ensure consistency.
The API ships JSON payloads with proper CORS headers and strictly enforces HTTPS. The service is containerized and runs behind a modern web server with continuous monitoring, metrics, and structured logging to support reliability at scale."
