Tony Shi developed a Batch Files Listing API with pagination for the instabase/aihub-openapi repository, focusing on scalable file retrieval within batch operations. He designed and implemented the new endpoint using YAML and the OpenAPI Specification, updating the API to support page_size and start_token parameters for efficient pagination. Tony enhanced the API’s documentation and example responses to streamline developer onboarding and integration, while also refactoring parameter handling and response structures for improved maintainability. His work emphasized API design, development, and documentation, resulting in a more reliable and traceable codebase that supports downstream integrations and future batch processing enhancements.
