kiosker-python-api 1.2.8

A python wrapper for the Kiosker API

Python wrapper for Kiosker API

This Python library provides a comprehensive wrapper for the Kiosker API, enabling developers to programmatically control and manage Kiosker devices. Kiosker is a professional web kiosk application for iOS that transforms iPads into secure, full-screen web browsers perfect for public displays, interactive kiosks, and digital signage solutions.

The kiosker-python-api package allows you to:

• Remote Control: Navigate web pages, refresh content, and control browser functions
• Device Management: Monitor device status, battery levels, and system information
• Content Control: Manage blackout screens for maintenance or emergency messaging
• Screen Management: Control screensaver behavior
• System Maintenance: Clear cookies, cache, and perform system operations
• Network Discovery: Automatically discover Kiosker devices on your network using ZeroConf

Whether you're managing a single kiosk or deploying a fleet of devices across multiple locations, this library provides the tools needed to integrate Kiosker devices into your existing infrastructure and workflows.

Installation

pip install kiosker-python-api

---

Setup

KioskerAPI(host, token, port = 8081, ssl = False, verify = False)

from kiosker import KioskerAPI
from kiosker import Status, Result, Blackout, ScreensaverState
api = KioskerAPI('10.0.1.100', 'token')

Constructor Parameters

• host (str): IP address or hostname of the Kiosker device
• token (str): Authentication token for API access
• port (int, optional): Port number (default: 8081)
• ssl (bool, optional): Use HTTPS instead of HTTP (default: False)
• verify (bool | ssl.SSLContext, optional): SSL certificate verification. Set to False to disable SSL verification for self-signed certificates (default: False)

---

Device Discovery with ZeroConf

Kiosker devices advertise themselves on the local network using ZeroConf (Bonjour/mDNS) autodiscovery. This allows you to automatically discover Kiosker devices without needing to know their IP addresses beforehand.

Service Information

Kiosker devices broadcast the following service:

• Service Type: _kiosker._tcp
• TXT Records:
  • version: App version (e.g., "25.1.0 (230)")
  • app: App name (e.g., "Kiosker Pro")
  • uuid: Unique device identifier (e.g., "2904C1F2-93FB-4954-BF85-FAAEFBA814F6")

Exception Handling

The kiosker-python-api defines custom exceptions to provide clear error handling for different failure scenarios:

Exception Hierarchy

All custom exceptions inherit from the base KioskerException class:

from kiosker.exceptions import (
    KioskerException,
    ConnectionError,
    AuthenticationError,
    IPAuthenticationError,
    TLSVerificationError,
    BadRequestError,
    PingError
)

Exception Types

• KioskerException: Base exception for all Kiosker API errors
• ConnectionError: Raised when connection to the Kiosker device fails
• AuthenticationError: Raised when authentication fails
• IPAuthenticationError: Raised when IP-list authentication fails
• TLSVerificationError: Raised when TLS verification fails
• BadRequestError: Raised when the request is invalid
• PingError: Raised when ping operation fails

Usage Example

from kiosker import KioskerAPI
from kiosker.exceptions import ConnectionError, AuthenticationError

try:
    api = KioskerAPI('10.0.1.100', 'invalid_token')
    result = api.ping()
except ConnectionError:
    print("Could not connect to the Kiosker device")
except AuthenticationError:
    print("Authentication failed - check your token")
except KioskerException as e:
    print(f"Kiosker API error: {e}")
