energa24-api 0.2.2

Async/sync Python client for the 24.energa.pl self-care portal

energa-api

Python client library for the 24.energa.pl self-care portal. Reverse-engineered from browser traffic. Supports both async and sync usage.

Features

• Authentication via OIDC Authorization Code + PKCE (Keycloak)
• Native Energa login and OrlenID federated login (shared Orlen Group account)
• Automatic token refresh with transparent re-login on session expiry
• List clients and accounts
• Fetch account balance
• List invoices (with date range and pagination)
• Download invoice PDFs

Installation

From PyPI

pip install energa24-api

From source (with uv)

git clone https://github.com/vincentto13/energa24-api.git
cd energa-api
uv sync

Configuration

Set credentials for one (or both) of the following:

Env vars	Login mode	Notes
ORLENID_USERNAME + ORLENID_PASSWORD	OrlenID (oid-ws.orlen.pl)	Shared across Orlen Group services. Takes priority if both are set.
ENERGA_USERNAME + ENERGA_PASSWORD	Native 24.energa.pl	Use if you have a standalone Energa account.

cp .env.example .env
# edit .env

Usage

Async

from energa import EnergaClient

# Native Energa credentials (24.energa.pl username/password)
async with EnergaClient("[e-mail]", "energa-password") as client:
    ...

# OrlenID credentials (shared Orlen Group account — oid-ws.orlen.pl)
async with EnergaClient("[e-mail]", "orlenid-password", use_orlenid=True) as client:
    for account in client.accounts:
        balance = await client.get_balance(account.account_number)
        print(balance.balance, "PLN")

        invoices = await client.get_invoices(account.account_number)
        for inv in invoices:
            print(inv.invoice_number, inv.amount, "PLN")

        # Download a PDF
        pdf = await client.download_invoice(account.account_number, inv.dms_id)

Sync

from energa import EnergaClientSync

with EnergaClientSync("[e-mail]", "orlenid-password", use_orlenid=True) as client:
    balance = client.get_balance(account_number)
    invoices = client.get_invoices(account_number)
    pdf = client.download_invoice(account_number, dms_id)

Development

MCP server — local setup with Claude Code

1. Install the MCP extra

uv sync --extra mcp

2. Export your credentials

# OrlenID (recommended — works across all Orlen Group services)
export ORLENID_USERNAME=[e-mail]
export ORLENID_PASSWORD=your-orlenid-password

# — or — native Energa credentials
export ENERGA_USERNAME=[e-mail]
export ENERGA_PASSWORD=your-energa-password

Persist in ~/.bashrc / ~/.zshrc so they're always available.

3. Verify the server starts

uv run python -m energa.mcp_server

The process should start and wait for MCP input on stdin (no output is normal — that's correct stdio behaviour). Press Ctrl+C to stop.

4. Connect Claude Code

The repo includes a .mcp.json that points Claude Code at the server automatically. Open Claude Code from this project directory — it will pick up .mcp.json and prompt you to approve the server on first use.

Check the connection inside a Claude Code session:

/mcp

You should see energa listed as connected with 4 tools.

Running the smoke test (live API)

# OrlenID credentials
ORLENID_USERNAME=[e-mail] ORLENID_PASSWORD=orlenid-secret uv run scripts/smoke_test.py

# Native Energa credentials
ENERGA_USERNAME=[e-mail] ENERGA_PASSWORD=energa-secret uv run scripts/smoke_test.py

Or with a .env file:

uv run --env-file .env scripts/smoke_test.py

Running the test suite

uv run pytest

MCP Server

The library ships an MCP server that exposes your Energa account as tools for Claude and other MCP-compatible AI assistants.

Install

pip install energa24-api[mcp]

Available tools

Tool	Description
list_accounts	List all accounts and meters (cached, no network request)
get_balance	Get current balance for an account
get_invoices	List invoices with optional date range and pagination
download_invoice	Download a PDF invoice — saves to a temp file and returns the path

Run standalone

# OrlenID credentials
ORLENID_USERNAME=[e-mail] ORLENID_PASSWORD=orlenid-secret uv run python -m energa.mcp_server

# Native Energa credentials
ENERGA_USERNAME=[e-mail] ENERGA_PASSWORD=energa-secret uv run python -m energa.mcp_server

Claude Desktop configuration

Add to ~/.config/claude/claude_desktop_config.json:

{
  "mcpServers": {
    "energa": {
      "command": "uv",
      "args": ["run", "--project", "/path/to/energa-api", "python", "-m", "energa.mcp_server"],
      "env": {
        "ORLENID_USERNAME": "[e-mail]",
        "ORLENID_PASSWORD": "your-orlenid-password"
      }
    }
  }
}

Use ORLENID_USERNAME/ORLENID_PASSWORD for OrlenID, or ENERGA_USERNAME/ENERGA_PASSWORD for native Energa. If both are set, OrlenID takes priority.

Note: The access token (5 min) is refreshed automatically. If the refresh token expires after 30 minutes of inactivity, the client silently re-logs in (up to 2 attempts) before raising an error — no manual restart needed in most cases.

Example prompts

Ask Claude naturally:

• "What's my Energa balance?"
• "Show me my last 3 invoices"
• "List all my electricity accounts and their meter addresses"
• "Download the latest invoice for account 1234567890"
• "Do I have any unpaid invoices?"

Acknowledgements

This library was built with the help of Claude (Anthropic's AI assistant). Claude assisted with reverse-engineering the authentication flow from browser HAR captures, designing the library architecture, implementing the async/sync client, and writing the test suite.
