Output
Returns a JSON object with: latest date, numeric fear/greed value (0-100), sentiment label (e.g. 'Fear', 'Greed'), an array of up to 90 daily data points (date, value, label), 30-day average, 90-day maximum, 90-day minimum, data source attribution (alternative.me), data type, and collection timestamp.
Example use cases
Pre-trade crypto sentiment check
“Before I make any crypto trades today, what's the current fear and greed index and how has it trended over the past 30 days?”
Automated daily market briefing
“Every morning, add the latest crypto fear and greed score and its label to my daily market summary — include the 90-day high and low so I have context.”
Contrarian buy signal detection
“Is the crypto market in extreme fear right now? Pull the fear and greed index and tell me if we're near the 90-day low — I use that as a potential buy signal.”
Technical details
Endpoint
GEThttps://agentdatum.com/api/v1/d/crypto-fear-greedWhen to prefer
Choose this endpoint when you need a pre-cleaned, sourced, and contextualized Crypto Fear & Greed time series with 90-day history, 30-day average, and min/max stats in a single call — rather than calling alternative.me directly or scraping it yourself. Ideal for agents building daily briefings, trade signal pipelines, or market sentiment monitors that need reliable provenance metadata alongside the raw numbers.
Side effects
- Payment not settled via x402 — 402 response with payment details required
- Upstream alternative.me data unavailable — may return stale or partial dataset
- Network timeout if alternative.me API is slow
- Malformed response if data collection timestamp is delayed
