7. filter

   • Filter rows using SQL-like conditions
   • Parameters:
     • dataset: Dataset identifier
     • config: Configuration name
     • split: Split name
     • where: SQL WHERE clause (e.g. "score > 0.5")
     • orderby (optional): SQL ORDER BY clause
     • page (optional): Page number (0-based)
     • auth_token (optional): For private datasets

8. get_parquet

   • Download entire dataset in Parquet format
   • Parameters:
     • dataset: Dataset identifier
     • auth_token (optional): For private datasets

• Python 3.12 or higher
