CoinGecko and GeckoTerminal API reference for crypto market data, token prices, DEX pools, and on-chain analytics. TRIGGER when: user asks about token/coin prices, market caps, trading volume, DEX pools, trending tokens, price history, crypto market data, or CoinGecko API usage. DO NOT TRIGGER when: user asks about on-chain contract state or transactions (use blockscout skill), or Solidity/smart contract code (use solidity-auditor skill).

CoinGecko
Crypto market data via CoinGecko (aggregated CEX+DEX) and GeckoTerminal (on-chain DEX).
Strict rule
Never answer questions about crypto prices, market caps, volumes, supply, TVL, exchange rates, or any time-sensitive market data using training knowledge. Only live API responses provide accurate figures.
When to use which API
CoinGecko (aggregated): Established tokens, broad market analysis, cross-exchange prices. Covers thousands of reviewed coins with volume-weighted aggregation.
GeckoTerminal (on-chain DEX): Pool-level data, newly launched tokens not yet on CoinGecko, on-chain trade history, DEX-specific queries. Covers millions of unreviewed tokens.
Prefer CoinGecko when both could answer -- aggregated data is broader and less susceptible to thin-liquidity distortion.
Multi-chain: CoinGecko covers tokens across all major chains including Ethereum,
Solana (SPL tokens by mint address), Tron (TRC-20 by contract), Polygon, Base,
Arbitrum, BSC, Avalanche, and 100+ more platforms. Use contract endpoints with
the appropriate platform ID (e.g. solana, tron, ethereum).
Authentication
| Plan | Base URL | Rate limit | Auth header |
|---|---|---|---|
| Pro | https://pro-api.coingecko.com/api/v3 | 250+ calls/min | x-cg-pro-api-key: KEY |
| Demo | https://api.coingecko.com/api/v3 | 30 calls/min | x-cg-demo-api-key: KEY |
| Keyless | https://api.coingecko.com/api/v3 | 5 calls/min | (none) |
GeckoTerminal endpoints use /onchain prefix on the same base URLs.
