Get the current price, market cap, and 24h trading volume for a Hedera token.
AI agents call token_price to retrieve information from Hedera Toolbox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
token_price retrieves publicly available market data about a Hedera token without modifying any state, executing code, or committing financial transactions. It is a straightforward data lookup with minimal blast radius even if misused by an agent, as the worst outcome would be stale or incorrect price information driving a downstream decision — not direct harm to systems or assets.
From the tool's definition Tool description states 'Get the current price, market cap, and 24h trading volume' — these are retrieval operations with no side effects. The verb 'Get' and the passive data points (price, market cap, volume) indicate query-only functionality.
