# Python API Tools Package

[![PyPI version](https://badge.fury.io/py/package-name.svg)](https://pypi.org/project/enindex_tools/)  
[![License: GPL v3](https://img.shields.io/badge/License-GPLv3-blue.svg)](LICENSE)


## Overview

This Python package provides a suite of tools to simplify interaction with the EnIndex API. 
This library abstracts the complexities of making requests, handling authentication and parsing results so you can focus on building your application.

---

## Features

- **Easy API Integration**: Streamlined methods for interacting with the EnIndex API.
- **Automated Chunking and Rate Limiting**: Large requests are automatically chunked and rate limited.
- **Authentication Handling**: Built-in support for API keys and token management.
- **Result Parsing**: Get results directly as a pandas dataframe or JSON.

---

## Installation

Install the package via pip:

```bash
pip install enindex-tools
```

---

## Usage

### 1. Create a .env file

Enindex tools uses [dotenv](https://pypi.org/project/python-dotenv/) to handle your config.  

You will need to add a new file to your project folder named ".env" containing the folowing environment variables.  

If you are able to log into the EnIndex platform you will have these details. Your API key can be found by clicking on the 
user menu in the top right of the platform:  

![Description of Image](assets/api_key.png)


E.g. if you log into https://alpha.enindex.com with the username jon.doe@acme.com your .env will look like this:  

```.env
ENINDEX_SUBDOMAIN = alpha
ENINDEX_USERNAME = jon.doe@acme.com
ENINDEX_API_KEY = 9fafec**********************************************************
```


### 2. Make Requests
```python
from enindex_tools import Api
import datetime as dt

# Initialize the Api
api = Api()

# Make a request
stack = api.get_stack_at(dt.datetime.now(),format='pandas')

# Do some analysis
print(f'NESO are spending £{stack["revenueRate"].sum()} per hour right now.')
```

## Contributing

The enindex_tools package is intended to be an open source project and contributions are welcomed. The github repo will be made public soon. For now, contact prj@enindex.com if you have suggestions.

## Acknowledgments

Thank you for using this package! We hope it simplifies your API interaction and accelerates your development process.

# API Class Documentation

## **`get_index`**

### Description:
Retrieves an index dataset within a specified time range and returns the data in the requested format.

### Parameters:
- **`dataset`** (`str`):  
  Identifier of the index dataset, e.g., `"NET_CCL_ND"`.
  
- **`time_from`** (`datetime.datetime`):  
  Start time of the query. If not on a minute boundary, it is rounded down to the prior minute boundary. Must include timezone information.

- **`time_to`** (`datetime.datetime`):  
  End time of the query. If not on a minute boundary, it is rounded up to the next minute boundary. Must include timezone information.

- **`format`** (`str`, optional):  
  Format of the returned data.  
  - `"json"`: Returns a list of `IndexSegment` objects.  
  - `"pandas"`: Returns a `pandas.DataFrame` object.  
  Default is `"json"`.

### Returns:
- **List[IndexSegment]** (if `format="json"`) or `pandas.DataFrame` (if `format="pandas"`).  
  Each `IndexSegment` contains:
  - `dataset` (`str`)
  - `timeFrom` (`str`)
  - `levelFrom` (`float`)
  - `timeTo` (`str`)
  - `levelTo` (`float`)

---

## **`get_stack_at`**

### Description:
Fetches the system stack at a specific time and returns it in the requested format.

### Parameters:
- **`time`** (`datetime.datetime`):  
  Time for which to retrieve the system stack. If not on a minute boundary, it is rounded down to the prior minute boundary. Must include timezone information.

- **`format`** (`str`, optional):  
  Format of the returned data.  
  - `"json"`: Returns a list of stack elements.  
  - `"pandas"`: Returns a `pandas.DataFrame` object.  
  Default is `"json"`.

### Returns:
- **List[StackElement]** (if `format="json"`) or `pandas.DataFrame` (if `format="pandas"`).  
  Stack elements include:
  - `timeType` (`str`)
  - `bmUnit` (`str`)
  - `elementId` (`int`)
  - `time` (`str`)
  - `elementType` (`str`)
  - `commitmentTime` (`int`)
  - `direction` (`str`)
  - `eFlaggedAccepted`, `eFlaggedNet`, `eFlaggedReversed` (`int`)
  - `mainPrice` (`float`)
  - `memberOf` (`list[str]`)
  - `noticeTime` (`int`)
  - `pairId` (`int`)
  - `quantity`, `quantityAccepted`, `quantityAvailable` (`float`)
  - `revenueRate` (`float`)
  - `reversePrice` (`float`)
  - `sFlaggedAccepted`, `sFlaggedNet`, `sFlaggedReversed` (`int`)
  - `side` (`str`)
  - `zeroToSel` (`bool`)
  - `zeroToSil` (`bool`)

> **Note:** Only elements with `timeType` = `"FROM"` are returned, corresponding to the instant immediately after the specified time.

---

## **`get_bmu_stack`**

### Description:
Retrieves stack elements for a specific BMU (Balancing Mechanism Unit) within a given time range.

### Parameters:
- **`bm_unit`** (`str`):  
  Identifier of the BMU, e.g., `"T_COSO-1"`.

- **`time_from`** (`datetime.datetime`):  
  Start time of the query. If not on a minute boundary, it is rounded down to the prior minute boundary. Must include timezone information.

- **`time_to`** (`datetime.datetime`):  
  End time of the query. If not on a minute boundary, it is rounded up to the next minute boundary. Must include timezone information.

- **`format`** (`str`, optional):  
  Format of the returned data.  
  - `"json"`: Returns a list of stack elements.  
  - `"pandas"`: Returns a `pandas.DataFrame` object.  
  Default is `"json"`.

### Returns:
- **List[StackElement]** (if `format="json"`) or `pandas.DataFrame` (if `format="pandas"`).  
  Stack elements include the same fields as `get_stack_at`.  

> **Note:** Both `timeType = "FROM"` and `timeType = "TO"` elements are included, representing the instant before and after the requested time.
