microservices currency forex webhooks caching
Prompt
Build a PHP microservice using Laravel and Lumen that aggregates live currency exchange rates from multiple external APIs (ECB, Bloomberg, Forex), with intelligent caching and fallback mechanisms. Implement a circuit breaker pattern to handle API failures, and create a webhook endpoint for instant rate updates. Design the service to support historical rate retrieval, cryptographic signing of exchange rate responses, and support for 200+ global currencies with microsecond response times.
