## SECURITY

This URL served no x402 challenge, so the only check that could run is the one that looks for one. A check that could not run reports `skip` and is never counted as a pass.

## RISK — not an x402 endpoint

This URL answered, but not with an x402 payment challenge, so there is nothing to score. That is a description of the response, not a finding about the endpoint.
