POST /api/v1/modal/sandbox/create

unprobed

Create a managed Python 3.11 sandbox. Two billing modes selected by 'timeout': ≤300s = flat rate (CPU $0.01, GPU varies). >300s = per-hour billing for the full requested lifetime, no refund on early terminate. Max 24h.

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