During January 2026, xFiLiNxCL developed and integrated support for a configurable API base URL in TavilyTools, enabling users to specify self-hosted or alternative Tavily API endpoints while maintaining backward compatibility. Working across the phidatahq/phidata and agno-agi/agno-docs repositories, they implemented this feature using Python, with a focus on robust API development and thorough unit testing. The work included updating documentation in Markdown to ensure clear user guidance and consistency across codebases. By validating changes, updating examples, and aligning with related issues and pull requests, xFiLiNxCL delivered a maintainable, flexible solution that enhanced deployment options without introducing regressions.
