JapanAPIs 0.1.1

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
