Target user
Developers who combine data from multiple external APIs
Problem
Developers need to combine data from multiple external APIs into a unified response with caching and error handling without building custom integration code for each source.
Requirements
- Configure multiple API data sources
- Transform and map API responses
- Cache responses with TTL
- Handle API errors gracefully
- Provide unified query endpoint
Core technologies
TypeScript, Hono, Redis
Completion criteria

- Implement rate limiting
- Add data merging strategies
- Support GraphQL federation
