CoinGecko Skill
🚫 CRITICAL: STOP — READ THIS BEFORE CALLING ANY TOOL
The #1 error is calling Coinglass tools instead of CoinGecko tools. They have similar names but are COMPLETELY DIFFERENT systems.
WRONG → RIGHT Tool Substitution Table
| ❌ NEVER call this | ✅ Call this instead | How to tell them apart |
|---|---|---|
cg_coins_market_data | cg_coins_markets | market_data=Coinglass derivatives. markets=CoinGecko spot. |
cg_ohlc_history | coin_ohlc | ohlc_history=Coinglass futures candles. coin_ohlc=CoinGecko spot candles. |
cg_pair_market_data | cg_coin_tickers | pair_market_data=Coinglass futures pair. coin_tickers=CoinGecko spot pairs. |
cg_supported_exchanges | cg_exchanges | supported_exchanges=Coinglass futures. exchanges=CoinGecko spot. |
cg_taker_exchanges | cg_exchange | taker=Coinglass volume. exchange=CoinGecko exchange info. |
cg_aggregated_taker_volume | cg_coin_tickers | taker_volume=Coinglass. coin_tickers=CoinGecko volume across exchanges. |
defillama_chains | cg_global_defi | For DeFi stats from CoinGecko, use cg_global_defi(). |
Also FORBIDDEN:
- ❌
web_search/web_fetch— ALL data is available via native CoinGecko tools above. NEVER use web_search for crypto market data. - ❌
bashfor data processing — CoinGecko tools return clean data. No bash needed. - ❌ NEVER answer with training data — all prices, rankings, OHLC are stale. CALL THE TOOL.
⚠️ MANDATORY TOOL CALLS — You MUST call a tool before answering these
| Request type | You MUST call | Why |
|---|---|---|
| K线 / OHLC / candlestick / open high low close | coin_ohlc(coin_id, days) | Price data is real-time; training data is stale |
| 走势图 / price chart / 价格趋势 | coin_chart(coin_id, days) | Same reason |
| 当前价格 / price right now | coin_price(coin_ids) | Training data has no live prices |
DO NOT return any numeric market data (prices, OHLC values, percentages) without calling a tool first.

🌳 Decision Tree
How many coins?
├─ ONE coin
│ ├─ Just price? → coin_price()
│ ├─ ATH/community/dev/deep? → cg_coin_data()
│ ├─ OHLC candles? → coin_ohlc()
│ ├─ Price trend? → coin_chart()
│ └─ Unknown ID? → cg_search() first
├─ MULTIPLE coins / ranking
│ ├─ Sector aggregate (板块总市值)? → cg_categories()
│ ├─ Sector individual (Meme前10)? → cg_coins_markets(category=X)
│ └─ General ranking? → cg_coins_markets(per_page=N)
├─ NFTs → cg_nfts_list() or cg_nft(nft_id)
├─ Exchange → cg_exchange(id) or cg_exchanges()
├─ Global → cg_global() or cg_global_defi()
└─ Token by contract → cg_token_price()
Common Category IDs

Output Formatting
- Prices: always use
$sign →$66,697 - Percentages: always use
%→+4.2% - NFT floor in ETH: show USD too →

Important Notes
- CoinGecko uses slug IDs: "bitcoin", "ethereum", "solana". Symbols (BTC, ETH, SOL) auto-resolve.
- If unsure about a coin ID →
cg_search(query="coin name")first. - Most questions need only 1-2 tool calls. Do NOT chain 3+ calls.
Common Issues
coin_price failed with invalid ID
Solution: Use cg_search(query="coin name") to find the correct CoinGecko ID first, or use the symbol directly (e.g., 'COMP').
