List all supported assets by category.

This tool performs a simple enumeration/listing of static reference data (supported assets) and has no side effects, write capabilities, or ability to execute operations. It is purely informational and carries minimal risk if misused by an AI agent, as the worst outcome would be retrieving information about what assets are available for trading.
