APIXU SDKs & Libraries: Development Tools & Guides (2026)

SDKs overview

APIXU, now operating as Weatherstack following its acquisition, offers a suite of Software Development Kits (SDKs) and libraries designed to facilitate integration with its weather data API. These tools abstract the complexities of direct HTTP requests, authentication, and JSON parsing, allowing developers to focus on application logic rather than API mechanics. The SDKs provide language-specific interfaces for accessing current weather, historical data, and future forecasts, aligning with the core products of the Weatherstack API Weatherstack API documentation. While APIXU itself no longer maintains separate SDKs, the Weatherstack documentation serves as the authoritative source for current integration methods.

Developers commonly use these SDKs and libraries for various applications, including embedding real-time weather information into websites, powering mobile application weather features, and integrating weather data into larger data analysis projects. The availability of multiple language-specific libraries ensures broad compatibility across different development environments, from web backends to data science platforms. The underlying API adheres to RESTful principles, often returning data in JSON format, which these SDKs are designed to consume and present in native data structures JSON-LD 1.1 specification.

Official SDKs by language

While the APIXU brand has transitioned to Weatherstack, the underlying API structure and the official integration methods are now documented under the Weatherstack umbrella. Weatherstack provides comprehensive examples and integration guides for several popular programming languages, which serve as the de facto official SDKs for former APIXU users. These examples demonstrate how to construct requests, handle API keys, and parse responses. The following table outlines commonly supported languages and typical installation methods, reflecting the official Weatherstack guidance:

For each language, the approach typically involves using a standard HTTP client library to make GET requests to the Weatherstack API endpoints and then parsing the JSON response. The Weatherstack documentation provides specific code examples Weatherstack API response examples for each of these primary languages, detailing how to query for current weather, historical data, and forecasts.

Installation

Installing the necessary components to interact with the Weatherstack API (formerly APIXU) primarily involves installing an HTTP client library for your chosen programming language. There isn't a single, monolithic SDK package for Weatherstack; instead, developers utilize common, well-maintained HTTP client libraries and follow the API's documentation for request construction and response parsing. The installation steps vary by language:

PHP

For PHP, Guzzle HTTP client is a widely used option. Install it via Composer:

composer require guzzlehttp/guzzle

Python

Python developers commonly use the requests library, which simplifies HTTP requests. Install it using pip:

pip install requests

Node.js

In Node.js environments, axios is a popular promise-based HTTP client. Install it with npm:

npm install axios

Ruby

Ruby applications can use libraries like httparty for making HTTP requests. Install it via RubyGems:

gem install httparty

Go

Go's standard library includes a robust net/http package, making external dependencies unnecessary for basic API interactions. No specific installation command is typically required beyond having a working Go environment.

After installing the HTTP client, developers obtain an API key from their Weatherstack account Weatherstack pricing and signup. This key is included in each API request, usually as a query parameter, to authenticate the application. The Weatherstack documentation provides specific endpoint URLs and parameter details for accessing different types of weather data.

Quickstart example

This quickstart example demonstrates how to fetch current weather data for a specific location using the Weatherstack API with Python's requests library. Replace YOUR_ACCESS_KEY with your actual API key and New York with your desired location.

import requests

# Replace with your Weatherstack API access key
ACCESS_KEY = 'YOUR_ACCESS_KEY'

# Define the location to query
LOCATION = 'New York'

# Construct the API request URL for current weather
api_url = f'http://api.weatherstack.com/current?access_key={ACCESS_KEY}&query={LOCATION}'

try:
    # Make the GET request to the Weatherstack API
    response = requests.get(api_url)
    response.raise_for_status() # Raise an HTTPError for bad responses (4xx or 5xx)

    # Parse the JSON response
    weather_data = response.json()

    # Check if the API returned an error (e.g., invalid access key, location not found)
    if 'success' in weather_data and weather_data['success'] == False:
        print(f"API Error: {weather_data['error']['info']}")
    else:
        # Extract and print relevant weather information
        current_temp = weather_data['current']['temperature']
        feels_like = weather_data['current']['feelslike']
        description = weather_data['current']['weather_descriptions'][0]
        humidity = weather_data['current']['humidity']

        print(f"Current Weather in {LOCATION}:")
        print(f"  Temperature: {current_temp}°C")
        print(f"  Feels like: {feels_like}°C")
        print(f"  Description: {description}")
        print(f"  Humidity: {humidity}%")

except requests.exceptions.HTTPError as http_err:
    print(f"HTTP error occurred: {http_err}")
except requests.exceptions.ConnectionError as conn_err:
    print(f"Connection error occurred: {conn_err}")
except requests.exceptions.Timeout as timeout_err:
    print(f"Timeout error occurred: {timeout_err}")
except requests.exceptions.RequestException as req_err:
    print(f"An unexpected error occurred: {req_err}")
except Exception as e:
    print(f"An error occurred: {e}")

This example demonstrates basic error handling and how to access specific fields within the JSON response. For more advanced queries, such as historical data or forecasts, consult the Weatherstack forecast API documentation for the correct endpoints and parameters.

Community libraries

Given the transition of APIXU to Weatherstack, many community-contributed libraries specifically branded for "APIXU" may no longer be actively maintained or might rely on deprecated endpoints. Developers are generally advised to prioritize official Weatherstack documentation and examples for robust and future-proof integrations. However, the open-source community often develops wrappers or client libraries for popular APIs, even if they are not officially endorsed.

When seeking community-contributed libraries for Weatherstack (or older APIXU implementations), developers might look on platforms like GitHub or package repositories (e.g., PyPI for Python, npm for Node.js). Key considerations for evaluating community libraries include:

• Active Maintenance: Check the last commit date, issue activity, and pull request status. Libraries that haven't been updated recently might not support the latest API features or changes.
• Documentation: Well-documented libraries are easier to use and troubleshoot.
• Community Support: A larger, active community can provide assistance and contribute to ongoing improvements.
• Compatibility: Ensure the library is compatible with the current Weatherstack API endpoints and authentication mechanisms.
• Licensing: Understand the open-source license under which the library is distributed.

For example, a search on GitHub for "Weatherstack client" or "Weatherstack API wrapper" might reveal various projects. Before integrating any community library, it is recommended to review its source code for security best practices and ensure it aligns with your project's requirements. For critical applications, direct integration using a standard HTTP client and the official Weatherstack documentation is often the most reliable approach, as it provides direct control and minimizes reliance on third-party code that may not be officially supported or frequently updated.
