⚡ Reliability
Best When
A crypto investor or developer wants AI agents to track cryptocurrency prices, monitor market data, and build portfolio analysis workflows using CoinGecko's comprehensive market data.
Avoid When
You need high-frequency trading data or on-chain DeFi analytics. Free CoinGecko tier has rate limits that constrain automated monitoring.
Use Cases
- • Querying real-time cryptocurrency prices from trading assistant and portfolio tracking agents
- • Monitoring price changes and market cap rankings for crypto research agents
- • Accessing historical price data for backtesting and analysis by AI finance agents
- • Building crypto price alert and portfolio valuation workflows via AI agents
Not For
- • High-frequency trading (CoinGecko free tier has rate limits)
- • On-chain DeFi data (CoinGecko is price aggregation, not on-chain data)
- • Stock market or traditional finance (crypto-specific)
Interface
Authentication
CoinGecko API key optional for free tier (Demo API). API key required for Pro API with higher rate limits.
Pricing
CoinGecko Demo API is free with registration. MCP server is free open source.
Agent Metadata
Known Gotchas
- ⚠ FINANCIAL RISK: Crypto price data used for trading decisions — verify data quality before acting
- ⚠ CoinGecko free tier: 30 req/min limit — monitor closely for portfolio tracking use cases
- ⚠ CoinGecko coin IDs differ from ticker symbols — use CoinGecko IDs (e.g., 'bitcoin' not 'BTC')
- ⚠ Price data has seconds-level delay — not suitable for millisecond-precision trading
