How this service works
483,000+ pay-per-call data APIs and free tools built on official sources — finance, company & government data, FRED, Census, crypto, calculators. USDC on Base via x402, native MCP. No API key, no signup.
Output
Returns a JSON object with the current Fear & Greed value (0-100 integer), its sentiment classification (e.g. 'Extreme Fear', 'Fear', 'Neutral', 'Greed', 'Extreme Greed'), a Unix timestamp, the source (Alternative.me), and an array of the last 7 daily readings each with value, timestamp, and classification.
Example use cases
Monitor sentiment before portfolio rebalancing
“Before I rebalance my crypto portfolio, what's the current Fear & Greed index saying about market sentiment? Give me today's reading and show me how it's trended over the past week.”
Alert on extreme market conditions
“Check the crypto Fear & Greed index for me right now. If it's hit 'Extreme Fear' or 'Extreme Greed', flag that for my attention so I know when there might be a contrarian opportunity.”
Track market psychology in trading strategy
“Pull the last 7 days of Fear & Greed readings and tell me what the pattern looks like — is sentiment getting more fearful, more greedy, or staying neutral? That'll help me decide if now's the right time to enter a position.”

Endpoint
GEThttps://api.gocreativeai.com/v1/crypto/fear-greed/%7Barg%7DWhen to prefer
Use this endpoint when you need real-time or recent crypto market sentiment as measured by the Fear & Greed index, especially when you want both the current reading and a 7-day trend in a single call. Prefer this over raw price data endpoints when the user is asking about overall market mood or sentiment rather than a specific asset price. At $0.01 USDC per call with no API key required, it is ideal for lightweight agent workflows.

- Invalid or unrecognized 'arg' path parameter returns an error or empty result
