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:

• Required for symbol-based actions:

Preferred request shape:
