fm-sdk-python
Python SDK for the Flexemarkets API.
Requirements
- Python 3.11+
Install
pip install fm-sdk
Configuration
The SDK loads credentials and endpoint from these sources (highest priority first):
- Arguments passed to
Flexemarkets.connect() - Files
~/.fm/credentialand~/.fm/endpoint(Java.propertiesformat) - Environment variable
FM_API_URL(defaults tohttps://api.flexemarkets.com)
Credential file
Create ~/.fm/credential:
account=myaccount
email=user@example.com
password=secret
Or use a bearer token:
token=eyJhbGciOiJIUzI1NiJ9...
Endpoint file
Create ~/.fm/endpoint:
endpoint=https://api.flexemarkets.com/api/marketplaces/123
SDK usage
from fm import Flexemarkets, OrderBooks, MarketplaceTrades
# Connect
fm = Flexemarkets.connect(
credential="~/.fm/credential",
endpoint="https://api.flexemarkets.com/api/marketplaces/123",
client_description="my-bot",
)
# REST API
marketplace_id = fm.endpoint_marketplace_id
markets = fm.markets(marketplace_id)
session = fm.session(marketplace_id)
holdings = fm.holdings(marketplace_id)
# Submit orders
order = fm.submit_limit(marketplace_id, market_id, "BUY", units=1, price=950)
fm.submit_cancel(marketplace_id, market_id, order.id)
# WebSocket events
import queue
q = queue.Queue(maxsize=1000)
fm.listen(marketplace_id, q)
books = OrderBooks(markets)
trades = MarketplaceTrades(markets)
while True:
event = q.get()
match event:
case list() as orders:
books.update(orders)
trades.update(orders)
case Session() as s:
print(s.state)
case Holding() as h:
print(h.cash)
fm.close()
The client also works as a context manager:
with Flexemarkets.connect(credential, endpoint, "my-bot") as fm:
...
