GET /api/v1/preflight

unprobed

Is this x402 endpoint safe to pay? Check it before your AI agent pays: go / caution / no_go, the recommended payment option, and why (payment would fail, over your budget, price above advertised, not HTTPS, unknown token). Never pays the endpoint. Cached 10 min.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
