ln-markets 2.0.5

LN Markets API python implementation

LN Markets Python API

A simple way to connect your Python application to LN Markets!

Install

You can install this package with pip:

pip3 install ln-markets

Use

You can import the rest class from lnmarkets

from lnmarkets import rest

And the websocket class as well

from lnmarkets import websockets

Authentication

For authentication you need your api key secret and passphrase

Without you will not bet able to authenticate

:warning: Never share your API Key, Secret or Passphrase

Websocket API

Configuration

Use the LNMarketsWebsocket and your key / passphrase to instanciate a new api connector:

options = {'key': 'your_api_key', 
           'secret': 'your_api_secret', 
           'passphrase': 'your_api_passphrase',
           'network': 'testnet'}

lnm = websockets.LNMarketsWebsocket(**options)
lnm.connect()

Check examples for more details as you'll need to extend this class most of the time.

Subscription

You can subscribe to LNM Markets public event such as futures last price ('futures:btc_usd:last-price') and index ('futures:btc_usd:index').

REST API Authentication

Using API key

Use the LNMarketsRest and your key / passphrase to instanciate a new api connector:

from lnmarkets import rest

options = {'key': 'your_api_key', 
           'secret': 'your_api_secret', 
           'passphrase': 'your_api_passphrase',
           'network': 'testnet'}

lnm = rest.LNMarketsRest(**options)

lnm.futures_get_ticker()

Using Mnemonic seed

Use the LNMarketsRest with BIP39 mnemonic phrase to instanciate a new api connector:

from lnmarkets import rest

mnemonic = 'struggle goddess action cheap endorse venue force tomato exercise cactus charge such'

lnm = rest.LNMarketsRest(mnemonic=mnemonic)

lnm.futures_get_ticker()

Mnemonic seed auth is a "hack" using the cookie used by LNM WebApp, so for avoid risk of stolen cookie, you should logout, when your program stop running:

lnm.logout()

The cookie have a lifetime (about 1 week), so if your program running for more than that time you might renew the cookie before expiry date (note that it can also be a safety measure tu renew your cookie often to avoid stolen cookies risk):

lnm.renew_cookie()
