Changes in version 0.1.1 (2025-11-30)                  

Bug Fixes

  - Improved error handling in all API functions to comply with CRAN
    policies regarding internet resources
  - All functions now fail gracefully with informative messages when
    APIs are unavailable or return errors
  - Added timeout handling (10 seconds) to prevent hanging connections
    during API requests
  - Added robust error handling with tryCatch() blocks for network
    errors, HTTP errors, and JSON parsing errors
  - Functions now return NULL with clear messages instead of throwing
    errors when API calls fail

Documentation Improvements

  - Updated all function examples to use \donttest{} instead of if
    (interactive()) to prevent issues during R CMD check
  - Enhanced documentation to clarify that functions return NULL when
    APIs are unavailable
  - Added more detailed error messages to guide users when connection
    issues occur
