GET /x402/options/gex/NVDA

live

News Gurus Intel API — dealer-regime classification for one equity/ETF symbol: regime label (e.g. positive_gamma_pinning / negative_gamma_amplifying) and gamma_bias (positive/negative/neutral) for squeeze and volatility analysis. Raw gamma dollar exposures are not redistributed. Educational data, not financial advice.

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).

The catalog declares GET. 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.
