The OrderBookApi class provides methods to interact with the CoW Protocol Order Book API, enabling operations like posting orders, obtaining quotes, retrieving trades, and managing order states.

​
Constructor

from cowdao_cowpy.order_book.api import OrderBookApi
from cowdao_cowpy.order_book.config import OrderBookAPIConfigFactory
from cowdao_cowpy.common.config import SupportedChainId

# Default (Mainnet production)
api = OrderBookApi()

# Custom configuration
api = OrderBookApi(
    OrderBookAPIConfigFactory.get_config("prod", SupportedChainId.MAINNET)
)

​
Initialization Examples

# Mainnet production
api = OrderBookApi(
    OrderBookAPIConfigFactory.get_config("prod", SupportedChainId.MAINNET)
)

# Gnosis Chain
api_gnosis = OrderBookApi(
    OrderBookAPIConfigFactory.get_config("prod", SupportedChainId.GNOSIS_CHAIN)
)

# Staging environment
api_staging = OrderBookApi(
    OrderBookAPIConfigFactory.get_config("staging", SupportedChainId.MAINNET)
)
