API Integration Builder

Build API service integrations:

• Create protocol in Services/{Domain}/

• Implement client: Async/await, proper errors

• Add caching: CacheManager integration

• Register in DI: DIContainer singleton

• Add tests: Mock for testing

Pattern:

protocol MyAPIProtocol { func fetch() async throws -> Data }

final class MyAPILive: MyAPIProtocol { func fetch() async throws -> Data { // URLSession, error handling, caching } }

Use when: Adding Bible translation API, CloudKit integration, external service
