Technical details
Endpoint
GEThttps://srv1553682.hstgr.cloud/fng/api/fear-greedWhen to prefer
Choose this endpoint when you need a simple, low-cost, pay-per-call read of the Crypto Fear & Greed index without setting up your own Alternative.me integration. It is ideal for agents that need real-time crypto sentiment data infrequently and want verifiable on-chain settlement via x402. Prefer the sibling composite market brief endpoint if you also need BTC/ETH spot prices and funding rates in one call.
Side effects
- Upstream Alternative.me API unavailability causing stale or missing data
- Network timeout from the hosting server
- Payment failure due to insufficient USDC balance for x402 microtransaction
- Rate limiting if called excessively in short intervals
