Twelve Data
Stocks, forex, and commodities price data. Traditional markets only — not for crypto.
Script Usage
This skill ships a single exports.py with all functions. Call it from a bash block:
python3 - <<'EOF'
import sys, json
sys.path.insert(0, "/data/workspace/skills/twelvedata")
from exports import twelvedata_price, twelvedata_quote, twelvedata_time_series
# Single quote
print(twelvedata_quote(symbol="AAPL"))
# Time series (last 30 daily candles)
series = twelvedata_time_series(symbol="AAPL", interval="1day", outputsize=30)
print(json.dumps(series.get("values", [])[:3], indent=2))
EOFAvailable functions in exports.py: twelvedataprice, twelvedataquote, twelvedatatimeseries, twelvedataeod, twelvedataquotebatch, twelvedatapricebatch, twelvedatasearch, twelvedatastocks, twelvedataforexpairs, twelvedataexchanges. Read exports.py directly when you need exact signatures.

| Asset class | Use | Why |
|---|---|---|
| Stocks (AAPL, TSLA) | TwelveData | CoinGecko has no stocks |
| Forex (EUR/USD) | TwelveData | CoinGecko has no forex |
| Commodities (gold, oil) | TwelveData | CoinGecko has no commodities |
| Crypto (BTC, ETH, SOL) | CoinGecko | TwelveData crypto data is limited/unreliable |
MISTAKES — Read Before Calling
❌ MISTAKE 1: Using TwelveData for crypto
User: "BTC 价格"
❌ WRONG: twelvedata_quote(symbol="BTC/USD")
✅ RIGHT: coin_price(ids="bitcoin") ← CoinGecko❌ MISTAKE 2: Calling quote individually for multiple stocks
User: "AAPL MSFT GOOGL 现在什么价"
❌ WRONG: twelvedata_quote("AAPL"), twelvedata_quote("MSFT"), twelvedata_quote("GOOGL") ← 3 calls
✅ RIGHT: twelvedata_quote_batch(symbols=["AAPL", "MSFT", "GOOGL"]) ← 1 call, up to 120 symbols❌ MISTAKE 3: Forex without slash
❌ WRONG: twelvedata_quote(symbol="EURUSD")
✅ RIGHT: twelvedata_quote(symbol="EUR/USD") ← always slash formatAlso: USD/CNH not USDCNH, GBP/JPY not GBPJPY.
❌ MISTAKE 4: Expecting bid/ask from quote
❌ WRONG: "EUR/USD bid: 1.0850, ask: 1.0852" ← quote only returns close
✅ RIGHT: "EUR/USD current price: 1.0851 (close/last price — bid/ask spread not available)"❌ MISTAKE 5: Wrong interval format
❌ WRONG: twelvedata_time_series(interval="1D") ← uppercase
✅ RIGHT: twelvedata_time_series(interval="1day")Valid: 1min, 5min, 15min, 30min, 1h, 2h, 4h, 8h, 1day, 1week, 1month
❌ MISTAKE 6: Using full output when compact suffices
User: "AAPL 最近走势"
❌ WRONG: twelvedata_time_series(symbol="AAPL", interval="1day", outputsize="full") ← 5000 candles
✅ RIGHT: twelvedata_time_series(symbol="AAPL", interval="1day", outputsize="compact") ← 30 candlesUse full only when user explicitly needs deep history.
