This service turns no meters of its own. Read the trap below for what it makes you pay for elsewhere.

Access Analyzer is the part that bills. External-access analyzers cost nothing, but unused-access analyzers charge per IAM role or user monitored and internal-access analyzers charge per AWS resource, monthly.

Find it on your bill
