🚫 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.
  • bash for 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

meme-token, artificial-intelligence, layer-1, layer-2, decentralized-finance-defi, gaming, real-world-assets-rwa

Output Formatting

  • Prices: always use $ sign → $66,697
  • Percentages: always use %+4.2%
  • NFT floor in ETH: show USD too → 5.17 ETH ($10,534)

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').
