description	Query public crypto exchange market data through CCXT. Use for ticker, order book, OHLCV, and symbol discovery. Do not use for balances or trading.

Use this skill for public market data only.

Rules:

1. Never call private account or trade actions.
2. Always pass exchange and action-specific required fields.
3. Prefer normalized fields when present in output.
4. If exchange does not support a method, return UNSUPPORTED_FEATURE.

Action Selection

• Use list_markets to discover available symbols and market metadata.
• Use fetch_ticker for latest price snapshot and 24h stats.
• Use fetch_order_book for bid/ask ladder and spread context.
• Use fetch_ohlcv for candle data across a timeframe.

For exact input/output examples, read references/actions.md.

Input Contract

• Required for all market actions: exchange
• Required for symbol-based actions: symbol (or payload.symbol for compatibility)
• Optional payload keys: limit, timeframe, since

Preferred request shape:

  "exchange": "binance",
  "action": "fetch_ticker",
  "symbol": "BTC/USDT",
  "payload": {}
}
