How this service works
CoinMarketCap Crypto Fear and Greed index (market sentiment): current value and classification, change versus yesterday, last week and last month, yearly high and low, and a 30-day daily series. Refreshed every 30 minutes. Use when an agent needs a sentiment gauge with recent history rather than a single reading. Payable in USDC on Base or Stellar, or XRP, RLUSD or USDC on the XRP Ledger. Not charged on stale data.
Output
A JSON object containing: current Fear & Greed index value and classification (e.g. 'Fear', 'Extreme Greed'), changes vs yesterday, last week, and last month, yearly high and low, a 30-day array of daily values, the data source (CoinMarketCap), freshness metadata (as_of, data_age_seconds, next_update, stale_after), and payment confirmation details (payer address, transaction hash, amount, network).
Example use cases
Pre-trade sentiment check
“Before I put in a buy order for Bitcoin, can you check the current crypto Fear & Greed index and tell me whether the market is in fear or greed right now, and how that compares to last week?”
Monthly sentiment review
“I want a summary of how crypto market sentiment has moved this month — pull the Fear & Greed index today versus a month ago, and show me the 30-day daily series so I can see the trend.”
Automated sentiment alert trigger
“Check the CoinMarketCap Fear & Greed index right now and tell me the current value and classification — I want to know if extreme fear or extreme greed has hit in the past day compared to yesterday.”

Endpoint
GEThttps://api.lumitrades.io/v1/fear-greed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the authoritative CoinMarketCap Fear & Greed index with full historical context (30-day series, yearly high/low, and multi-period change deltas) in a single call. Prefer it over general sentiment endpoints when you specifically need the standardized CMC index value with freshness guarantees and transparent staleness signaling. It is cheaper than broader sentiment bundles when you only need the Fear & Greed metric.
Side effects
- Bad input parameters — not charged, returns error JSON
- Stale data (index not refreshed in time) — not charged, returns stale indicator
- API unavailable or CoinMarketCap data feed disruption — may return 503 or error JSON
- Payment failure via x402 — call not executed, no charge
