How this service works
Crypto Fear & Greed index: today + yesterday + week ago + 10-day history (0=extreme fear, 100=extreme greed) — market sentiment in one call
Output
A JSON object containing the current Fear & Greed index integer value (0-100), its text classification (e.g. 'Greed', 'Fear', 'Neutral', 'Extreme Greed'), the value and classification from yesterday, the value and classification from 7 days ago, and an array of the last 10 days of daily readings — all sourced from alternative.me.
Example use cases
Daily trading sentiment check
“What's today's crypto Fear and Greed score, and has sentiment improved or gotten more fearful compared to yesterday and last week?”
Automated market mood monitoring
“Every morning, check the crypto Fear and Greed index and tell me whether it's shifted more than 10 points from a week ago.”
Contrarian buy signal detection
“Is the crypto market currently in extreme fear? I want to know the current Fear and Greed value and classification so I can decide whether to buy the dip.”
Technical details
Endpoint
GEThttps://money-reactor.makar52nn2016.workers.dev/api/fear-greed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, real-time snapshot of crypto market sentiment via the Fear & Greed index without requiring an API key or account setup. It is ideal for agent workflows that need micro-payment-gated, no-registration access to sentiment data paid per-call via x402/USDC on Base. Prefer this over scraping alternative.me directly when you want a structured JSON response with historical context included.
Side effects
- Payment not received or x402 handshake fails — 402 response with payment requirements
- Upstream alternative.me API unavailable — may return stale or error response
- Malformed response if the upstream data format changes
- Network timeout from Cloudflare Worker
