ip-fast.com

Overview

ip-fast.com provides a suite of API services primarily focused on IP address data, including geolocation and threat intelligence. Launched in 2020, the platform is designed for developers who require real-time information about an IP address to enhance application functionality, security, or user experience. The API can resolve an IP address to detailed geographical information such as country, region, city, and postal code. It also identifies the organization, ISP, and autonomous system number (ASN) associated with the IP address.

A key capability of ip-fast.com is its VPN and proxy detection service. This feature allows applications to identify when a user is attempting to mask their true location, which can be critical for fraud prevention, content rights management, and maintaining service integrity. For instance, e-commerce platforms can use this to flag suspicious transactions originating from known proxy servers, while streaming services can enforce geo-restrictions on content.

The service is well-suited for a range of applications, including website customization based on visitor location, which enables dynamic content serving or language localization. Fraud detection systems can leverage the IP data to analyze user origin and flag potential risks. Furthermore, content geo-targeting, such as delivering region-specific advertisements or news, is a common application. The API supports both IPv4 and IPv6 addresses, ensuring broad compatibility with current internet standards. Integration is facilitated by clear documentation and code examples in multiple programming languages, including Python, PHP, Node.js, Ruby, Java, and Go, allowing developers to choose their preferred environment. The API offers responses in both JSON and XML formats, providing flexibility for parsing data within different system architectures.

Key features

• IP Geolocation API: Provides precise geographical data for any IPv4 or IPv6 address, including country, region, city, latitude, and longitude. This information can be used for localizing content or analyzing user distribution.
• VPN/Proxy Detection: Identifies if an IP address belongs to a VPN, proxy, or Tor exit node. This helps in enhancing security measures and enforcing geo-restrictions by flagging suspicious or anonymized connections.
• ISP and Organization Data: Returns details about the Internet Service Provider (ISP) and the organization owning the IP address. This is useful for network analysis and understanding the origin of traffic.
• Time Zone Information: Delivers the time zone associated with the IP address's geographical location, which can be used for scheduling or time-sensitive application features.
• Currency and Language Data: Provides currency and primary language information relevant to the IP's location, aiding in localization efforts for e-commerce and international applications.
• ASN Lookup: Identifies the Autonomous System Number (ASN) and associated organization, providing insight into the network block an IP address belongs to, as described by the IETF's RFC 1930 on AS Guidelines.

Pricing

ip-fast.com offers a free tier and various paid plans structured around monthly request volumes. The pricing structure is designed to accommodate different usage levels, from individual developers to larger enterprises. As of May 2026, the available plans are summarized below. For the most current pricing details and any potential custom enterprise solutions, refer to the official ip-fast.com pricing page.

Common integrations

ip-fast.com's API is designed for direct integration into various application environments and workflows. Its support for standard data formats (JSON/XML) and multiple programming languages facilitates implementation across different systems.

• Web Applications: Integrate into web servers (e.g., using Node.js or PHP SDKs) to personalize content, enforce geo-restrictions, or detect suspicious login attempts based on visitor IP addresses.
• E-commerce Platforms: Utilize for fraud detection by cross-referencing transaction IP addresses with known proxy networks or inconsistent geographical data. This can complement services like Stripe Radar for fraud prevention.
• Analytics & Reporting Tools: Enrich website visitor logs with geographical data for more granular analytics on user demographics and traffic sources.
• Cybersecurity Systems: Incorporate into firewalls or intrusion detection systems to flag and block traffic from high-risk IP ranges, VPNs, or proxy servers.
• Content Management Systems (CMS): Enable dynamic content delivery based on the user's location, such as displaying region-specific promotions or news articles.
• Customer Relationship Management (CRM): Enhance customer profiles with geographical data to better understand customer locations and tailor communication strategies.

Alternatives

Several other providers offer IP geolocation and related services. While ip-fast.com focuses on straightforward integration and a competitive free tier, other solutions may offer different feature sets, data accuracy, or pricing models.

• IPinfo: Offers a comprehensive IP data API including geolocation, ASN, company, carrier, and privacy detection (VPN/proxy). Known for its robust dataset and developer tools.
• MaxMind GeoIP2: A widely used solution, available as both a downloadable database and an API service. MaxMind is recognized for its high accuracy in IP location data and is often a foundational component for many systems requiring precise geo-targeting.
• Abstract API - IP Geolocation API: Provides a simple, scalable IP geolocation API with features like city, country, postal code, and ISP information. It aims for ease of use and quick integration.

Getting started

To begin using the ip-fast.com API, you typically need to sign up for an API key on their website. Once you have your API key, you can make HTTP requests to their endpoints. The following Python example demonstrates how to perform a basic IP geolocation lookup using the requests library.

import requests
import json

# Replace with your actual API key from ip-fast.com
API_KEY = 'YOUR_API_KEY'

# The IP address to look up (e.g., Google's public DNS or any other IP)
IP_ADDRESS = '8.8.8.8'

# Construct the API request URL
# The ip-fast.com documentation provides specific endpoint details.
# This example assumes a common structure for geolocation requests.
# Always refer to the official ip-fast.com documentation for precise endpoint URLs:
# https://ip-fast.com/docs

url = f"https://api.ip-fast.com/ip/?ip={IP_ADDRESS}&api_key={API_KEY}"

try:
    response = requests.get(url)
    response.raise_for_status()  # Raise an HTTPError for bad responses (4xx or 5xx)

    data = response.json()

    print(f"Geolocation data for IP: {IP_ADDRESS}")
    print(f"Country: {data.get('country_name', 'N/A')}")
    print(f"City: {data.get('city', 'N/A')}")
    print(f"Latitude: {data.get('latitude', 'N/A')}")
    print(f"Longitude: {data.get('longitude', 'N/A')}")
    print(f"ISP: {data.get('isp', 'N/A')}")
    print(f"Is Proxy/VPN: {data.get('is_proxy', 'N/A')}")

except requests.exceptions.RequestException as e:
    print(f"An error occurred: {e}")
except json.JSONDecodeError:
    print(f"Failed to decode JSON response: {response.text}")

This Python script sends a GET request to the ip-fast.com API with a specified IP address and your API key. It then parses the JSON response and prints key geolocation data. Developers should consult the official ip-fast.com documentation for detailed API endpoints, request parameters, and response structures, as these may vary depending on the specific feature being utilized (e.g., geolocation vs. VPN detection).
