WHAT IT DOES

What getAllowance does on Agentek Eth

AI agents call getAllowance to retrieve information from Agentek Eth without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why getAllowance is rated Low

This tool performs a read-only query of ERC20 token allowance state on the blockchain. It retrieves information about how much token a spender is allowed to transfer on behalf of an owner, but makes no state changes. The blast radius is minimal—misuse cannot alter balances, approve additional spending, or move funds. It is purely informational.

From the tool's definition Tool name 'getAllowance' and description 'Gets the ERC20 token allowance between an owner and spender' indicate a query operation that retrieves existing allowance data without modification.
