## 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"))
print(cg_trending())
EOF
```

Read `exports.py` for the full list of available functions. Common ones:
`coin_price`, `coin_ohlc`, `coin_chart`, `cg_trending`,
`cg_top_gainers_losers`, `cg_new_coins`, `cg_global`, `cg_global_defi`,
`cg_categories`, `cg_derivatives`, `cg_coins_markets`, `cg_coin_data`,
`cg_coin_tickers`, `cg_search`, `cg_token_price`, `cg_coin_by_contract`.


# 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`.

### Prices & Charts
| Function | Description |
|---|---|
| `coin_price(coin_ids, timestamps=None, vs_currency='usd')` | Current or historical price. `coin_ids` = comma-string like `"bitcoin,ethereum"`. `timestamps` = list of unix ts for historical (default: now). |
| `coin_ohlc(coin_id, days=30, vs_currency='usd')` | OHLC bars for last N days. Returns list of `[ts, o, h, l, c]`. Granularity auto-selected: 1d=30min, 7-30d=4h, 30d+=4h. |
| `coin_chart(coin_id, days=30, vs_currency='usd')` | Price + market_cap + total_volume timeseries. Returns `{prices, market_caps, total_volumes}` (each list of `[ts, val]`). |

## 🚫 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').
