Get current price, 24h change, market cap, and volume for any coin by CoinGecko ID or symbol
AI agents call get_coin_price to retrieve information from Agenti without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries public cryptocurrency price information from CoinGecko. It retrieves data only and has no side effects on accounts, balances, or financial positions.

"get_coin_price": {}
}
