alsi-py 1.0.2

A library to query ALSI data

alsi-py

Python client for the ALSI API (Aggregated LNG Storage Inventory)

Documentation of the API can be found at: https://alsi.gie.eu/GIE_API_documentation_v004.pdf Documentation of the client API can be found at: https://roiti-ltd.github.io/alsi-py/

Installation

python3 -m pip3 install alsi-py

Usage

The package is split in two clients:

1. AlsiRawClient: Returns data in raw JSON format.
2. AlsiPandasClient: Returns parsed data in the form of a pandas dataframe.

from alsi.raw_client import AlsiRawClient
from alsi.pandas_client import AlsiPandasClient
from datetime import datetime
import asyncio

API_KEY = '<API_KEY>'

country_code = 'DE'
company_code = '21X000000001368W'
facility_code = '21W000000000100J'

async def main():
    client = AlsiRawClient(api_key=API_KEY)

    # Functions that return JSON.
    client.query_data_for_facility(facility_code, company_code, country_code)
    client.query_agg_data_for_europe_or_noneurope(europe='eu')
    client.query_agg_data_by_country(contry_code='BE')
    client.query_data_by_company_and_country(company_code, country_code)

    # Filter results by time
    client.query_agg_data_by_country(country_code, start=datetime(2017,1,1), end=datetime(2018,1,1), limit=10)

    # Create pandas client. All functions are the same as the raw client.
    pandas_client = AlsiPandasClient(api_key=API_KEY)

    # In the end of the code, make sure to close the client session:
    await client.close_session()
    # or
    await pandas_client.close_session()

asyncio.run(main())

export PYTHONPATH=./alsi
export ALSI_KEY='...'

Run unit tests in coverage mode

python -m pytest ./tests --import-mode=append --cov
