Real-Time Forex Rate Aggregation Microservice Architecture

microservices forex currency-conversion circuit-breaker
Prompt
Design a robust Node.js microservice that aggregates foreign exchange rates from multiple providers (Bloomberg, Reuters, Fixer.io) with intelligent fallback mechanisms. Implement circuit breaker patterns to handle API failures, create a caching layer using Redis that expires every 5 minutes, and develop a weighted average calculation for more accurate currency conversion rates. Include comprehensive error handling, rate limiting, and a GraphQL endpoint for flexible querying.
