Numerai Python API

Automatically download and upload data for the Numerai machine learning competition.

This library is a Python client to the Numerai API. The interface is programmed in Python and allows downloading the training data, uploading predictions, and accessing user, submission and competitions information. It works for both, the main competition and the newer Numerai Signals competition.

If you encounter a problem or have suggestions, feel free to open an issue.

Installation

pip install --upgrade numerapi

Usage

Numerapi can be used as a regular, importable Python module or from the command line.

Some actions (like uploading predictions or staking) require a token to verify that it is really you interacting with Numerai's API. These tokens consists of a public_id and secret_key. Both can be obtained by login in to Numer.ai and going to Account -> Custom API Keys. Tokens can be passed to the Python module as parameters or you can be set via environment variables (NUMERAI_PUBLIC_ID and NUMERAI_SECRET_KEY).

Python module

Usage example - main competition

import numerapi
# some API calls do not require logging in
napi = numerapi.NumerAPI(verbosity="info")
# download current dataset
napi.download_current_dataset(unzip=True)
# get competitions
all_competitions = napi.get_competitions()
# get current leaderboard
leaderboard = napi.get_leaderboard()
# check if a new round has started
if napi.check_new_round():
    print("new round has started within the last 24hours!")
else:
    print("no new round within the last 24 hours")

# provide api tokens
example_public_id = "somepublicid"
example_secret_key = "somesecretkey"
napi = numerapi.NumerAPI(example_public_id, example_secret_key)

# upload predictions
model_id = napi.get_models()['uuazed']
napi.upload_predictions("preds.csv", model_id=model_id)
# check submission status
napi.submission_status(model_id)
# increase your stake by 1.2 NMR
napi.stake_increase(1.2)

# convert results to a pandas dataframe
import pandas as pd
df = pd.DataFrame(napi.daily_user_performances("uuazed"))

Usage example - Numerai Signals

import numerapi

napi = numerapi.SignalsAPI()
# get current leaderboard
leaderboard = napi.get_leaderboard()

# setup API with api tokens
example_public_id = "somepublicid"
example_secret_key = "somesecretkey"
napi = numerapi.SignalsAPI(example_public_id, example_secret_key)

# upload predictions
model_id = napi.get_models()['uuazed']
napi.upload_predictions("preds.csv", model_id=model_id)

# get submission status and invalid tickers
status = napi.submission_status(model_id)
invalid_tickers = status['invalidTickers']

# get daily performance as pandas dataframe
import pandas as pd
df = pd.DataFrame(napi.daily_user_performances("uuazed"))
