POST /cryptovar/x402/risk_verify

unprobed

Verify a CryptoVar Black-Scholes VaR artifact by replaying its parameters, result and audit proof. 0.10 USDC. Returns valid true/false and the expected SHA-256 proof. An invalid artifact is a completed verification, not a service failure. CryptoVar artifacts only; no certification of model assumptions or future losses. Automatic delivery, 30-minute SLA. Idempotency-Key required.

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