⚠️ The legacy secret token feature was removed in 3x-UI 2.6.0. ⚠️ The project also supports optional bearer token authentication with the token constructor argument or XUI_TOKEN environment variable for panels that expose token auth.

Sync and Async Object-oriented Python SDK for the 3x-ui API.

Overview • Quick Start • Examples • Bugs and Feature Requests • Documentation • PyPI

ℹ️ If you need a JavaScript SDK, check out js3xui.

Overview

This SDK is designed to interact with the 3x-ui app in a more object-oriented way. It provides both synchronous and asynchronous methods to interact with the app. The SDK is designed to be as simple as possible to use, while still providing a lot of flexibility and uses Pydantic models to validate the data.
Used dependencies:

• requests for synchronous API
• httpx for asynchronous API
• pydantic for models

Supported Python versions:

• 3.11
• 3.12

Since the 3x-ui app is under development, the SDK may not be compatible with all versions of the app. The developer of SDK is not related to the 3x-ui app, therefore the latest versions of the software are not guaranteed to be compatible with the SDK.
The SDK does not support versions of the 3x-ui older than 2.3.7.

Quick Start

You can use both synchronous and asynchronous methods to interact with the 3x-ui app. Both APIs have the same methods and return the same data, so it's up to you to choose which one to use.
After installing the SDK, you can create a new instance of the API. When creating a new instance, you can either use environment variables or pass the credentials directly. It's strongly recommended to use environment variables to store the API credentials.
On creation, the Api won't connect to the 3x-ui app, so you can spawn new instances without spending resources. But after creating an instance, you'll need to call the login method to authenticate the user and save the cookie for future requests.

Installation

pip install py3xui

Create a new instance of the API

It's recommended to use an environment variable to store the API credentials:

import os

os.environ["XUI_HOST"] = "http://your-3x-ui-host.com:2053"
os.environ["XUI_USERNAME"] = "your-username"
os.environ["XUI_PASSWORD"] = "your-password"

To work synchronously:

from py3xui import Api

# Using environment variables:
api = Api.from_env()

# Or using the credentials directly:
api = Api("http://your-3x-ui-host.com:2053", "your-username", "your-password")

For synchronous token authentication, set XUI_TOKEN instead of XUI_USERNAME and XUI_PASSWORD, or pass token directly:

from py3xui import Api

api = Api("http://your-3x-ui-host.com:2053", token="your-api-token")

To work asynchronously:

from py3xui import AsyncApi

# Using environment variables:
api = AsyncApi.from_env()

# Or using the credentials directly:
api = AsyncApi("http://your-3x-ui-host.com:2053", "your-username", "your-password")

*️⃣ If you're using a custom URI Path, ensure that you've added it to the host, for example:
If your host is http://your-3x-ui-host.com:2053 and the URI Path is /test/, then the host should be http://your-3x-ui-host.com:2053/test/.
Otherwise, all API requests will fail with a 404 error.

Using TLS and custom certificates

Interacting with server over HTTPS requires careful management of TLS verification to ensure secure communications. This SDK provides options for setting TLS configurations, which include specifying custom certificates for increased trust or disabling TLS verification when necessary.

Case 1: Disabling TLS verification

For development, you can disable TLS verification. This is not recommended for production due to the increased risk of security threats like man-in-the-middle attacks.

api = Api("http://your-3x-ui-host.com:2053", "your-username", "your-password", use_tls_verify=False)

❗ Warning: Never disable TLS verification in production.

Case 2: Using сustom сertificates

If you are interacting with a server that uses a self-signed certificate or one not recognized by the standard CA bundle, you can specify a custom certificate path:

api = Api(
	"http://your-3x-ui-host.com:2053",
	"your-username",
	"your-password",
	custom_certificate_path="/path/to/your/certificate.pem",
)

This allows you to maintain TLS verification by providing a trusted certificate explicitly.

Login

When using username/password authentication, call the login method to authenticate the user and save the cookie for future requests. The API first fetches the CSRF token from the csrf-token endpoint and sends it with the login request.

from py3xui import Api, AsyncApi

api = Api.from_env()
api.login()

async_api = AsyncApi.from_env()
await async_api.login()

When the synchronous Api is created with token or XUI_TOKEN, do not call login; requests are authenticated with the Authorization: Bearer ... header.

Using two-factor authentication

If you enabled two-factor authentication in the 3x-ui app, you'll need to pass the two-factor code to the login method. The code can be either a string or an integer.

from py3xui import Api, AsyncApi

api = Api.from_env()
api.login("123456")  # Replace with your actual two-factor code.

async_api = AsyncApi.from_env()
await async_api.login("123456")  # Replace with your actual two-factor code.

Note, that the two-factor code is being changed every 30 seconds, so you need to ensure that you pass the correct code when calling the login method. If you don't pass the code, the login will fail.
Keep in mind, that the session cookie has it's own expiration time, so you may need to call the login method again after some time while providing the new two-factor code. So, it's recommended to have some sort of automation to retrieve the valid two-factor code from time to time.

ℹ️ As an example of solution to automate the two-factor code retrieval, you can use the pyotp library to generate the code based on your secret key.
