Look up a specific dataset and return detailed information about it. IMPORTANT: Always use this function before querying a new dataset to understand its required parameters and schema. The returned information includes: 1. Required parameters for the dataset (IMPORTANT for datasets like 'balances' that need an address) 2. Schema details showing available columns and data types 3. Example queries for the dataset When the dataset requires specific parameters like 'address' (for 'balances'), ALWAYS use the 'contract' parameter in query_dataset() to pass these values. Example: For 'balances' dataset, lookup_dataset('balances') will show it requires an 'address' parameter. You should then query it using: query_dataset('balances', blocks='1000:1010', contract='0x1234...') Args: name: The name of the dataset to look up sample_start_block: Optional start block for sample data (integer) sample_end_block: Optional end block for sample data (integer) use_latest_sample: If True, use the latest block for sample data sample_blocks_from_latest: Number of blocks before the latest to include in sample Returns: Detailed information about the dataset including schema and available fields
