Answer 1

Binance offers both cross-margin trading (where all margin is in one account) and isolated margin trading (where each pair is a separate margin account).

Get cross-margin asset info

info = client.get_margin_asset(asset='BNB')

Get cross-margin symbol info

info = client.get_margin_symbol(symbol='BTCUSDT')

Get isolated margin symbol info

info = client.get_isolated_margin_symbol(symbol='BTCUSDT')
