Endpoint
GEThttps://earn-pulse.haiqingm58.workers.dev/fngWhen to prefer
Choose this endpoint when you need a quick, real-time snapshot of aggregate crypto market sentiment without any filtering or parameterization. It is ideal for agents building market dashboards, pre-trade decision logic, or daily briefings that incorporate sentiment alongside price data. Prefer this over scraping news sentiment tools when you want a single canonical numeric sentiment index rather than qualitative analysis.
Side effects
- Upstream data source unavailable — returns 5xx error
- Stale data if the upstream Fear & Greed provider has not updated recently
- Payment not fulfilled (x402 payment required before data is returned)
- Network timeout on the Cloudflare Worker edge node
