Script Usage

Script-mode skill — read this file, then invoke from a bash block:

bash

python3 - <<'EOF'
import sys, json
sys.path.insert(0, "/data/workspace/skills/coingecko")
from exports import coin_price, cg_trending, cg_global
 
print(coin_price(coin_ids="bitcoin,ethereum"))

CoinGecko Skill

Function Reference (signatures)

All public functions are in exports.py. coin_id is the CoinGecko id (e.g. bitcoin, ethereum) — use cg_search(query) first if unsure. vs_currency defaults to usd.

🚫 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').
