Navigating the API Usage Landscape: Challenges and AI-Based Solutions


In today’s digital age, Application Programming Interfaces (APIs) play a pivotal role in connecting various applications and services, enabling data sharing and driving innovation across industries. APIs serve as the digital bridge between organizations and platforms, facilitating seamless data exchange and enhancing user experiences. However, as the usage of APIs continues to surge, so do the associated cybersecurity risks. This article explores the evolving API landscape, delves into the challenges posed by API security, and discusses how Artificial Intelligence (AI) can bolster API security measures.

The exponential surge in Application Programming Interface (API)

In today’s digitally interconnected world, Application Programming Interfaces (APIs) are the unsung heroes that enable seamless data sharing between applications and services. These digital connectors act as intermediaries, bridging the gap between organizations, enterprises, and platforms, all in pursuit of innovation, expanded reach, the discovery of new business models, and the growth of partner networks.

APIs empower your product or service to communicate effortlessly with other offerings, without the need to delve into the intricacies of their internal workings. They simplify app development, streamline the integration of various product functionalities, and ultimately save precious time and resources while delivering a frictionless user experience.

The usage of APIs has witnessed an exponential surge in recent years, with Akamai estimating that a staggering 83% of internet traffic is now driven by these digital connectors. Furthermore, a survey conducted by Slashdata reveals that nearly 90% of developers incorporate APIs into their projects in some form or another.

The API Security Challenge

APIs have become the backbone of modern software development, powering everything from mobile applications to Internet of Things (IoT) devices. This increasing dependence on API, in turn, is leading to API security becoming a serious concern as it not only expands the attack surface but also introduces new security risks. In addition, there could be severe consequences for consumers, businesses, and third-party providers in case of API breaches.

While they offer unparalleled flexibility and efficiency, APIs also introduce significant security challenges.

  1. Rising API Dependency: A report by Slashdata reveals that nearly 90% of developers use APIs in some capacity, emphasizing their growing importance in software development. However, increased API reliance expands the attack surface, making organizations more vulnerable to security breaches.
  2. API Abuse: As the number of API calls continues to grow, so does the potential for abuse. A study by Salt Security reported that approximately 91% of surveyed organizations experienced API security incidents in 2020. Moreover, API attacks increased by over 600% from 2021 to 2022.
  3. Business Logic Attacks: Sophisticated attackers now target the business logic of APIs, exploiting vulnerabilities in ways that traditional security measures struggle to detect. These attacks manipulate the flow of API calls and can have devastating consequences.
  4. Complexity of API Ecosystems: Organizations often manage a complex ecosystem of APIs, making it challenging to maintain security across all endpoints and track changes effectively.

The shift from monolithic architectures to microservices in clouds and containers has revolutionized development cycles but at the same time increased the vulnerabilities exposed to the internet. The use of Kubernetes and other microservices is now a crucial component of APIs. Over 3,80,000 vulnerable Kubernetes API servers were recently discovered by a study, which is concerning because the Kubernetes API server is an essential control plane component for container deployment.

API Security in the Financial Sector

The financial services industry has witnessed a transformative impact from APIs, with the rise of Fintech and Open Banking. Open Banking enables third-party financial service providers to access consumer banking and financial data through APIs. While APIs offer opportunities for innovation and enhanced customer experiences, they also present new security concerns.

APIs in the financial sector grant access to sensitive customer information, making them attractive targets for cyberattacks. API-related security incidents not only erode consumer trust but also damage an organization’s brand reputation. As a result, the financial sector is increasingly becoming a preferred target for API attacks.

Common Types of API Attacks

Understanding the nature of API attacks is crucial for effective protection. Here are some common types of API attacks:

  1. Broken Access Control: Unauthorized users gain access to restricted resources, compromising data integrity.
  2. Security Misconfiguration: Improperly defined security options and insecure default settings can lead to vulnerabilities.
  3. Cross-Site Scripting (XSS) Attacks: Malicious scripts are injected into trusted websites, compromising user data and system integrity.
  4. Excessive Data Exposure: Inadvertently revealing too much information to clients can lead to data breaches.
  5. SQL Injection: Attackers use malicious SQL code to manipulate databases, accessing sensitive information.
  6. Man-in-the-Middle (MITM) Attacks: Perpetrators intercept communication between users and applications for eavesdropping or impersonation.
  7. DDoS Attacks: Overwhelming the target infrastructure with excessive Internet traffic disrupts normal operations. DDOS attacks are very common and during one well-known incident, the system of the affected entity was hit by a volume of traffic ranging up to 1.35 terabits per second and the attack lasted for over 20 minutes which was launched by tens of thousands of unique end points orchestrated by more than a thousand different autonomous systems (ASNs).

AI-Based Solutions for API Security

While traditional security methods like Web Application Firewalls (WAFs) and API gateways provide essential protection, they may not be sufficient to thwart sophisticated API attacks. The evolving threat landscape necessitates a more advanced and adaptive approach to API security, which is where Artificial Intelligence (AI) comes into play.

Key Advantages of AI-Based API Security:

  1. Behavior Analysis: AI models can learn and identify normal user behavior patterns across APIs, detecting anomalies that may indicate malicious activity. This dynamic approach is effective against business logic attacks.
  2. Granular User-Level Insights: AI models can provide granular insights into user behavior, allowing organizations to pinpoint and address security threats on an individual level.
  3. Real-Time Detection: AI-powered systems can offer real-time threat detection, enabling swift responses to emerging security incidents.
  4. Adaptive Learning: AI models can adapt to changing API landscapes and emerging attack vectors, making them a robust defense against evolving threats.

Challenges of AI-Based API Security:

  1. Data Quantity and Quality: AI models require large datasets for training. Smaller APIs or those with limited traffic may face challenges in generating sufficient training data.
  2. Interpretable Models: AI models can be black boxes, making it challenging to understand how they make decisions. This opacity can be a concern in regulatory compliance.
  3. Overfitting: Overfitting can occur when AI models are trained on limited or noisy data, potentially leading to false positives.
  4. Continuous Monitoring: Maintaining and updating AI models to adapt to evolving API landscapes requires ongoing effort and expertise.


As APIs continue to shape our digital world, API security remains a paramount concern. The sophistication of API attacks calls for equally sophisticated defense mechanisms. AI-based solutions, with their ability to learn, adapt, and analyze user behavior, are becoming indispensable in protecting against evolving API threats. While challenges exist in implementing AI-based security, organizations must recognize the importance of staying ahead of cyber adversaries in our interconnected, API-driven landscape. API security is not just a matter of technology; it’s a crucial aspect of trust and reliability in our digitally connected ecosystem.
