AI agents call get_fiat_balance to retrieve information from Bybit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns fiat balance data without side effects. While fiat balance is financial-domain information, the tool itself only reads/retrieves it—no money moves, no transactions execute, and no accounts are modified. It is a simple informational query, making it a Read category risk with low severity.
From the tool's definition Tool name 'get_fiat_balance' and description 'Get fiat balance' indicate a read-only operation that retrieves account balance information without modifying, executing transactions, or causing financial movements.
