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 the current Fear & Greed Index value (typically a 0–100 numeric score), a sentiment label such as 'Extreme Fear', 'Fear', 'Neutral', 'Greed', or 'Extreme Greed', and likely a timestamp. The number of results returned can be controlled via the `limit` query parameter.
Example use cases
Daily crypto sentiment check
“What is today's Fear & Greed Index for the crypto market? I want to know the score and whether it's in fear, greed, or neutral territory.”
Trading signal for DCA strategy
“Before I buy more ETH, can you pull the current Fear & Greed Index? I only want to buy when it's in extreme fear territory.”
Market mood for portfolio report
“I'm writing a weekly crypto portfolio update — grab the latest Fear & Greed Index score so I can include the current market sentiment reading.”

Endpoint
GEThttps://acp-x402-discovery.onrender.com/x402/fear-greed-indexWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call crypto market sentiment signal settled in USDC on Base via the x402 protocol. Ideal for agents operating in crypto-native environments that already support x402 micropayments and need a quick Fear & Greed reading without a subscription. Prefer alternatives (e.g. free public APIs like Alternative.me) if x402 payment infrastructure is not available or if you need historical data beyond what the limit parameter provides.
Side effects
- Payment not settled — 402 response if USDC payment via x402 is not included or insufficient
- Network timeout from hosted Render service (cold start latency on free tier)
- Empty or malformed response schema — response schema is documented as an empty example object, so structure may be undocumented
- Rate limiting or provider downtime if underlying data source is unavailable
