• Methods construction
  • Generating session request id by default
  • Creating request on-the-fly from method name and params: {}
  • Generating signature if necessary
  • Response handling
• logging

User interface layer

• Start session instance
• Getting session operational status
• Send async request
• Get response or raised exception
• Stop session instance

Get started

Install use PIP

pip install crypto_ws_api

For upgrade to latest versions use:

pip install -U crypto_ws_api

After first install create environment by run

crypto_ws_api_init

in terminal window.

The config directory will be created. You get path to config ws_api.toml

Prepare exchange account

• For test purpose log in at Binance Spot Test Network
• Create API Key
• After install and create environment specify api_key and api_secret to the config file

Start demo

• Run in terminal window

crypto_ws_api_demo

Useful tips

crypto_ws_api/demo.py - complete and fully functional example

Get credentials and create user session

from crypto_ws_api.ws_session import get_credentials, UserWSSession

session = aiohttp.ClientSession()
_exchange, _test_net, api_key, api_secret, ws_api_endpoint = get_credentials(account_name)

user_session = UserWSSession(
    api_key,
    api_secret,
    session=session,
    endpoint=ws_api_endpoint
)

await user_session.start()
print(f"Operational status: {user_session.operational_status}")

Demo method's calling

await account_information(user_session)

Stop user session and close aiohttp session

await user_session.stop()
await session.close()
print(f"Operational status: {user_session.operational_status}")

Method call example

async def account_information(user_session: UserWSSession):
    # https://developers.binance.com/docs/binance-trading-api/websocket_api#account-information-user_data
    try:
        res = await user_session.handle_request(
            "account.status",
            api_key=True,
            signed=True
        )
        if res is None:
            print("Here handling state Out-of-Service")
    except asyncio.CancelledError:
        pass  # Task cancellation should not be logged as an error
    except Exception as _ex:
        print(f"Handling exception: {_ex}")
    else:
        print(f"Account information (USER_DATA) response: {res}")

Limits control :link:

Upon reaching the limit threshold of each type, the session switches to the Out-of-Service state. Monitor the values of the variables user_session.operational_status and user_session.order_handling

If you send a request in this state, the answer will be None

In any case, you are protected from exceeding limits and blocking for this reason
