Graph Countries SDKs & Libraries: Integration Guide (2026)

SDKs overview

Graph Countries offers a RESTful API for accessing country data and performing lightweight geocoding operations. As of 2026-05-29, Graph Countries explicitly states that it does not provide official Software Development Kits (SDKs) or client libraries. This design choice means developers integrate with the API by making direct HTTP requests. This section outlines the implications of this approach, providing guidance on how to interact with the Graph Countries API, and discusses potential community-driven solutions.

The absence of official SDKs means that developers are responsible for handling HTTP communication, request authentication, data serialization (e.g., JSON parsing), and error handling within their chosen programming language. This approach offers maximum flexibility and avoids dependencies on specific library versions, but it requires more boilerplate code compared to using a pre-built SDK. Developers can refer to the official Graph Countries documentation for detailed API endpoints, request formats, and response structures.

Official SDKs by language

Graph Countries does not distribute official SDKs for any programming language. The platform's developer experience notes confirm that there are no official SDKs, and integration relies on direct HTTP requests. This means developers will typically use standard HTTP client libraries available in their programming language of choice to interact with the Graph Countries API.

For example, in Python, developers might use the requests library; in JavaScript, fetch or axios; in Java, HttpClient; and in C#, HttpClient. These libraries facilitate sending GET and POST requests, setting headers (including API keys for authentication), and parsing JSON responses. The Graph Countries API is designed to be straightforward, reducing the complexity typically associated with direct API integration.

The following table, therefore, indicates the absence of official SDKs:

Installation

Since there are no official SDKs for Graph Countries, installation primarily involves setting up an HTTP client library in your preferred programming language. The specific installation steps depend on the language and package manager being used.

Python

To make HTTP requests in Python, the requests library is a common choice. Install it using pip:

pip install requests

JavaScript (Node.js/Browser)

For Node.js environments, axios is a popular promise-based HTTP client. For browser environments, the native Fetch API is available, or axios can also be used.

To install axios in Node.js:

npm install axios
# or
yarn add axios

Java

Java 11 and later include a built-in HttpClient. For earlier versions or more advanced features, external libraries like Apache HttpClient or OkHttp can be used. If using Maven, add a dependency for Apache HttpClient:

<dependency>
    <groupId>org.apache.httpcomponents.client5</groupId>
    <artifactId>httpclient5</artifactId>
    <version>5.2.1</version>
</dependency>

PHP

Guzzle is a widely used HTTP client for PHP. Install it via Composer:

composer require guzzlehttp/guzzle

Ruby

The httparty gem provides a convenient way to make HTTP requests in Ruby. Install it using Bundler or RubyGems:

gem install httparty
# or add to your Gemfile
gem 'httparty'

Quickstart example

This quickstart demonstrates how to fetch data from the Graph Countries API using direct HTTP requests in Python. Ensure you have an API key, which can be obtained by signing up on the Graph Countries homepage. Replace YOUR_API_KEY with your actual key.

Python Example: Fetching Country Details

This example retrieves details for a specific country using its ISO 2-letter code.

import requests
import json

# Replace with your actual Graph Countries API key
API_KEY = "YOUR_API_KEY"
BASE_URL = "https://api.graphcountries.com/v1"

def get_country_details(country_code):
    headers = {
        "Authorization": f"Bearer {API_KEY}",
        "Content-Type": "application/json"
    }
    endpoint = f"{BASE_URL}/country/{country_code}"
    
    try:
        response = requests.get(endpoint, headers=headers)
        response.raise_for_status()  # Raise an exception for HTTP errors (4xx or 5xx)
        return response.json()
    except requests.exceptions.HTTPError as http_err:
        print(f"HTTP error occurred: {http_err}")
        print(f"Response content: {response.text}")
    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}")
    return None

if __name__ == "__main__":
    country_data = get_country_details("US") # Example: United States
    if country_data:
        print("Successfully fetched country data:")
        print(json.dumps(country_data, indent=2))
        print(f"Country Name: {country_data.get('name')}")
        print(f"Capital: {country_data.get('capital')}")
        print(f"Population: {country_data.get('population')}")
    else:
        print("Failed to retrieve country data.")

    print("\n--- Trying another country ---")
    country_data_fr = get_country_details("FR") # Example: France
    if country_data_fr:
        print("Successfully fetched country data for France:")
        print(f"Country Name: {country_data_fr.get('name')}")
        print(f"Currency: {country_data_fr.get('currencies', [{}])[0].get('code')}")
    else:
        print("Failed to retrieve country data for France.")

This script defines a function get_country_details that constructs the necessary headers with the API key and makes a GET request to the specified country endpoint. It includes basic error handling for common HTTP and request-related issues. The Graph Countries API documentation provides further details on available endpoints and request parameters.

Community libraries

Given the absence of official SDKs, the Graph Countries developer community may develop and maintain third-party libraries to simplify integration. These libraries typically wrap the direct HTTP calls into more idiomatic functions or classes for specific programming languages, reducing the boilerplate code required for API interaction.

As of this writing, specific, widely adopted community-maintained libraries for Graph Countries are not prominently listed or endorsed on their official channels. Developers seeking such libraries are advised to search public code repositories like GitHub, GitLab, or package managers (e.g., PyPI for Python, npm for JavaScript) for packages that mention "Graph Countries" or "GraphCountries API".

When considering a community-contributed library, it is important to evaluate its:

• Maintenance status: Is it actively maintained and updated?
• Documentation: Is there clear documentation and examples?
• Community support: Are there active issues, pull requests, or forums?
• Security: Does it handle API keys securely and follow best practices?
• API coverage: Does it cover the specific API endpoints and features you need?

Before integrating any third-party library, it is recommended to review its source code and ensure it aligns with your project's security and quality standards. For direct interaction, developers can always refer to general best practices for RESTful API consumption and HTTP client usage in their chosen language.

If a suitable community library is not found, or if precise control over API requests is required, direct HTTP integration using native language features or general-purpose HTTP client libraries (as demonstrated in the installation and quickstart sections) remains the most reliable and officially supported method for interacting with the Graph Countries API.
