The IP Fraud Score API is designed to measure the level of risk associated with an IP address using a scoring system that combines multiple technical and contextual signals. Its purpose is to help digital platforms prevent fraud, abuse, and suspicious access before they impact service operations. The endpoint response provides a clear and structured view of the risk, classified into understandable levels such as low, medium, or high.
At the core of the API is the fraud score, a numerical value that represents the probability that an IP address is related to fraudulent activities. This indicator is complemented by risk labels and logical flags that facilitate automated decision-making, such as allowing, limiting, or blocking a connection. In addition, the API indicates whether the IP address should be considered high risk, simplifying its integration into existing security flows.
The information returned includes network operator data, such as the Internet service provider, autonomous system, and host name, providing additional context about the origin of the traffic. Approximate geographic details are also provided, useful for detecting regional anomalies or validating expected location in authentication processes.

The API returns a comprehensive evaluation of an IP address, including a fraud score, risk level, risk label, network operator details, geographic location, anonymization signals, and blacklisting status. This data helps assess the likelihood of fraudulent activity associated with the IP.
Key fields in the response include "fraud_score," "risk_level," "risk_label," "operator" (ISP details), "location" (geographic info), "anonymization" (VPN/Tor status), and "external_blacklists" (blacklisting status). Each field provides critical insights for risk assessment.
The response data is structured in a JSON format, with top-level keys representing the IP address evaluation, including nested objects for "operator," "location," and "anonymization." This organization allows for easy parsing and integration into applications.
The API provides information on fraud risk, including the fraud score, risk levels, network operator data, geographic location, anonymization status, and whether the IP is blacklisted. This comprehensive data aids in fraud prevention and risk management.
Users can customize requests by specifying the IP address they wish to evaluate in the API call. The API processes this input to return tailored risk assessments based on the provided IP, allowing for targeted fraud detection.
The data is sourced from various network intelligence providers, including ISPs and security databases. This diverse sourcing helps ensure a broad coverage of IP addresses and enhances the accuracy of fraud risk assessments.
Typical use cases include fraud detection in online transactions, user authentication validation, and monitoring suspicious access patterns. Businesses can leverage the API to enhance security measures and reduce the risk of fraudulent activities.
Users can utilize the returned data by integrating it into their security workflows. For example, they can automate actions based on the fraud score and risk level, such as blocking high-risk IPs or flagging them for further review, enhancing overall security.
To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process. Once subscribed, return to the API page and you will see your API Access Key displayed at the top of the documentation page. You can use this key to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
The free trial lasts for 7 days and allows you to make up to 50 API requests.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes. If the API offers a free trial, you will see a "Free 7-Day Trial" option in its Pricing section. The trial lasts for 7 days and allows up to 50 API requests, enabling you to evaluate the API before subscribing to a paid plan.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription.
