The order book endpoint provides an order book's bids and asks and can be used in streaming mode.
When filtering for a specific order book, you must use use all six of these arguments: base_asset_type, base_asset_issuer, base_asset_code, counter_asset_type, counter_asset_issuer, and counter_asset_code. If the base or counter asset is XLM, you only need to indicate the asset type as native and do not need to designate the code or the issuer.
