MCP-native · works in Claude & Cursor

Quick Start for AI Agents

Add the MCP server in one line — then your agent answers crypto questions by calling the API for you. No endpoints to wire up, no keys to juggle. Just ask.

Claude · cryptodataapi connected
What's the Fear & Greed index today, and how does BTC funding look?
On it — pulling sentiment and derivatives now.
⚙GET/sentiment/fear-greed
⚙GET/derivatives/binance/summary?symbol=BTCUSDT
Fear & Greed is 61 — Greed (up from 54 yesterday). BTC funding is +0.011%, open interest $8.2B, long/short 1.18. Sentiment and positioning are both leaning bullish.
Find trending Solana pools and flag anything that looks like a rug.
⚙GET/dex/trending?chain=solana
⚙GET/dex/security/solana/{token}
Top 3 trending: $WIF, $POPCAT, $MEW. Two pass the security check; one new pool flags mint authority not revoked — I'd treat it as high-risk.
