cofy-api 0.3.0

An open-source modular framework for ingesting, standardising, storing, and computing energy-related data.

Cofy Cloud is an open-source modular framework for ingesting, standardising, storing, and computing energy-related data, designed to run anywhere from local deployments to cloud environments.

Right now this is very much a work in progress. With the development of a first proof of concept. This is not ready for production use and the api is likely to change significantly in the near future.

Setup

Install

pip install "cofy-api[all]"

Cofy is modular — install only what you need via extras. Example — install with only the tarrif and members modules:

pip install "cofy-api[tariff,members]"

Configure

Quick start

Create an app.py with a minimal Cofy API:

from cofy import CofyApi
from cofy.modules.tariff import TariffModule

app = CofyApi()
app.register_module(TariffModule(api_key="YOUR_ENTSOE_KEY", name="entsoe"))

Run it:

fastapi dev app.py

The API is now available at http://127.0.0.1:8000 with interactive docs at /docs.

Authentication

Protect the API with bearer-token authentication:

from fastapi import Depends

from cofy import CofyApi
from cofy.api import token_verifier

app = CofyApi(
    dependencies=[Depends(token_verifier({"my-secret-token": {"name": "Admin"}}))]
)

Clients authenticate via header (Authorization: Bearer my-secret-token) or query parameter (?token=my-secret-token).

Full example

The demo/ directory contains a complete working application that ties everything together.

Development

We use astral python tooling for our development environment. We use poethepoet to define some essential tasks. The demo run task is also available as vscode execution task, making it easy to run and debug the demo application from within vscode.

Install/update dependencies:

First install uv if you don't have it yet.

Then install/update dependencies:

uv sync

Install poethepoet and pre-commit

uv tool install poethepoet
uv tool install pre-commit

Activate pre-commit hooks that enforce code style on every commit:

pre-commit install

Run development demo application:

Our demo application uses some API keys for external services. You can provide these .env.local file in the root of the repository, following the structure of .env.example.

poe demo

Code style checks:

poe lint    # Check code style
poe format  # Format code
poe check   # Run type checks

Run tests:

poe test

Build & publish

We use a github action to create a new tag, github release and publish to pypi. Trigger the action manually from the actions tab, and provide the new version number as input.
