Integration Patterns

Service-to-service integration is HTTP-based with strict schemas.

Key integration flows

• Auth → Profile: create profile on successful registration or OAuth login
• Orchestration → Data: price, indicators, news, and instrument search
• Orchestration → Pattern: prediction signals
• Orchestration → Profile: portfolio and risk context
• Frontend → Services: proxy via /api/* to avoid CORS fragmentation

Best practices

• Use consistent JSON schemas and version the API
• Pass correlation IDs for distributed tracing
• Use timeouts and retries for idempotent operations
