GET /timing/fng

unprobed

Crypto Fear & Greed index with a market-timing trend: current value and classification, 7-day and 30-day deltas, streak in the current regime, 30-day min and max, and a contrarian flag on extreme fear or greed. Keyless.

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

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.
