Python client for dYdX (v3 API).

The library is currently tested against Python versions 2.7, 3.4, 3.5, and 3.6

Installation

The dydx-v3-python package is available on PyPI. Install with pip:

pip install dydx-v3-python

Getting Started

The Client object can be created with different levels of authentication depending on which features are needed. For more complete examples, see the examples directory, as well as the integration tests.

Public endpoints

No authentication information is required to access public endpoints.

from dydx3 import Client
from web3 import Web3

#
# Access public API endpoints.
#
public_client = Client(
    host='http://localhost:8080',
)
public_client.public.get_markets()

Private endpoints

One of the following is required:

  • api_key_credentials
  • eth_private_key
  • web3
  • web3_account
  • web3_provider
#
# Access private API endpoints, without providing a STARK private key.
#
private_client = Client(
    host='http://localhost:8080',
    api_key_credentials={ 'key': '...', ... },
)
private_client.private.get_orders()
private_client.private.create_order(
    # No STARK key, so signatures are required for orders and withdrawals.
    signature='...',
    # ...
)

#
# Access private API endpoints, with a STARK private key.
#
private_client_with_key = Client(
    host='http://localhost:8080',
    api_key_credentials={ 'key': '...', ... },
    stark_private_key='...',
)
private_client.private.create_order(
    # Order will be signed using the provided STARK private key.
    # ...
)

Onboarding and API key management endpoints

One of the following is required:

  • eth_private_key
  • web3
  • web3_account
  • web3_provider
#
# Onboard a new user or manage API keys, without providing private keys.
#
web3_client = Client(
    host='http://localhost:8080',
    web3_provider=Web3.HTTPProvider('http://localhost:8545'),
)
web3_client.onboarding.create_user(
    stark_public_key='...',
    ethereum_address='...',
)
web3_client.api_keys.create_api_key(
    ethereum_address='...',
)

#
# Onboard a new user or manage API keys, with private keys.
#
web3_client_with_keys = Client(
    host='http://localhost:8080',
    stark_private_key='...',
    eth_private_key='...',
)
web3_client_with_keys.onboarding.create_user()
web3_client_with_keys.api_keys.create_api_key()
