A JSON array. Each market includes instrument_id, instrument_name, instrument_type, underlying_asset, quote_asset, price_step (tick size), amount_step, min_order_value, max_order_value, max_notional_value, max_leverage (perpetuals, omitted when unknown), mark_price and index_price (null when unavailable), funding_rate, open_interest, volume_24h, maker_fee / taker_fee (perpetuals only; null when unknown) and base_decimals / quote_decimals (18 for perpetuals).
