How this service works
Crypto Fear & Greed Index: current and previous value with classification, plus recent history. A contrarian input — extreme fear has historically marked accumulation zones and extreme greed distribution zones — but it is a filter, never a trigger on its own. Pair it with funding to separate real capitulation from a crowded short.
Output
Returns the current Crypto Fear & Greed Index numeric value (0–100) and its classification (e.g. Extreme Fear, Fear, Neutral, Greed, Extreme Greed), the previous value with its classification, and a short recent history of index readings — all usable as a contrarian sentiment filter for crypto market positioning.
Example use cases
Pre-trade sentiment check
“Before I put in a Bitcoin buy order, can you pull the Fear & Greed Index and tell me if we're in extreme fear or extreme greed right now, and what it was the past few days?”
Contrarian accumulation zone alert
“I'm watching for extreme fear readings in crypto that might signal a good accumulation zone — what does the Fear & Greed Index say today compared to recent history?”
Market regime context for portfolio rebalancing
“I'm reviewing my crypto portfolio allocation this week — pull the current Fear & Greed Index value and classification so I know whether sentiment is leaning fearful or greedy before I rebalance.”
Technical details
Endpoint
POSThttps://crypto-asistent.com/api/x402/data/fear-greed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured sentiment reading — specifically the Fear & Greed Index — as a filter or context layer for crypto trading decisions, market commentary, or portfolio review. It is especially useful when combining sentiment with funding rates, dominance data, or macro catalysts from sibling endpoints on the same platform. Prefer it over a generic AI crypto analyst endpoint when you need the raw index value and classification rather than an interpreted stance.
