How this service works
Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).
Output
Returns one or more Fear & Greed Index data points, each including a numeric score (0–100), a sentiment label (e.g. 'Extreme Fear', 'Greed', 'Extreme Greed'), and a timestamp. The number of results is controlled by the 'limit' query parameter (default 1).
Example use cases
Pre-trade sentiment check
“Before I buy any crypto today, can you pull the current Fear & Greed Index so I know whether the market is panicking or euphoric?”
Daily market sentiment report
“Every morning include the latest Fear & Greed Index score in my crypto briefing so I can track whether sentiment is shifting toward fear or greed.”
Historical sentiment trend review
“Get me the last 5 Fear & Greed Index readings so I can see how market sentiment has moved over the past few days.”

Endpoint
GEThttps://acp-x402-scriptmasterlabs.onrender.com/x402/fear-greed-indexWhen to prefer
Choose this endpoint when you need a quick, micropayment-gated (no API key setup) crypto Fear & Greed Index reading via the x402 protocol settled in USDC on Base. It is ideal for AI agents that already have x402 payment capability and want a low-cost, per-call sentiment signal without managing API subscriptions.
Side effects
- Payment not settled — 402 response if x402 USDC payment on Base is not properly attached
- Invalid limit parameter — non-integer or out-of-range value may return a 400 error
- Upstream data unavailable — if the underlying Fear & Greed data source is down, may return a 503 or empty result
- Rate limits or server cold start on Render free tier may cause intermittent 504 timeouts
