What the probe found
A cross-origin preflight came back without Access-Control-Allow-Origin, so the endpoint is reachable from native clients only — code running in a web page is stopped by the browser before a request is ever sent.
The server exposes a public surface before authorization: a2awire_guide, find_paid_work, get_recommended_action, check_earnings, register, discover_agents, onboard_start, hire_and_execute, verify_contract, get_agent_contract.
