How this service works
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.
Output
Returns the current Fear & Greed index value and its textual classification (e.g. 'Fear', 'Extreme Greed'), the 7-day and 30-day point deltas, the number of consecutive days in the current sentiment regime (streak), the 30-day minimum and maximum values, and a boolean contrarian flag indicating whether conditions of extreme fear or extreme greed suggest a potential market reversal signal.
Example use cases
Contrarian buy signal detection
“Check the Bitcoin Fear & Greed index and let me know if we're in extreme fear territory right now — I want to know if the contrarian flag is triggered and how long we've been in this regime.”
Weekly sentiment trend report
“Pull the current Fear & Greed index for Bitcoin and tell me how it's changed over the past 7 and 30 days — I'm writing my weekly crypto market update.”
30-day sentiment range review
“What were the highest and lowest Fear & Greed readings for Bitcoin over the past 30 days, and where does the current reading sit relative to that range?”
Technical details
Endpoint
GEThttps://api.agentstools.dev/timing/fngWhen to prefer
Choose this endpoint when you need a pre-computed, multi-dimensional sentiment dashboard for crypto — not just a raw index number, but trend context (7-day and 30-day deltas), regime persistence (streak), historical range (30-day min/max), and a ready-made contrarian signal flag. Ideal for agents making timing-aware trading or reporting decisions without needing to compute derivatives themselves. Prefer this over raw index feeds when the agent needs actionable context, not just a snapshot.
