GET /api/v1/preflight/batch
unprobed
Are these x402 endpoints safe to pay? Up to 10 endpoints in one call (?url=a&url=b): per endpoint go / caution / no_go, the recommended payment option and why, plus totals. For marketplaces and agents that weigh several services. Never pays the endpoints.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
