Developed and integrated a new TransactionHistory UI for the pollinations/pollinations repository, enhancing the Pollen Dashboard and Activity page with detailed visibility into API usage and per-request cost deductions. The work involved building responsive React components in TypeScript and JavaScript, implementing compact previews and full transaction tables, and ensuring theming consistency across different pages. API integration enabled real-time data display, including API key name resolution and robust formatting for small transaction values. The codebase was refactored to streamline status rendering and remove deprecated props, with all changes validated for zero TypeScript errors and no breaking changes to existing API contracts.
