POST /quant/risk
method-gated
Portfolio risk metrics over an array of periodic returns: value-at-risk, conditional VaR, Sharpe, Sortino, max drawdown, Calmar, volatility, and more. Pure computation over your inputs.
Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
