AI agents call get_measurement to retrieve information from Airly without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves air quality measurements for a specified location. It performs a query operation that reads existing data without creating, modifying, or deleting any resources. The action is non-destructive and has no side effects beyond returning information to the caller, making it a clear Read category tool with low severity.
