About

What is Link Shield?

Link Shield offers an AI-powered URL scanning API designed to detect and prevent phishing, malware, and other suspicious links. It provides real-time analysis and transparent scoring details, allowing developers to integrate robust link protection into their applications. The API evaluates URLs, identifies suspicious patterns, and reviews redirect behavior to uncover hidden destinations. It returns a risk score from 0-100 along with reasons, enabling teams to confidently block, warn, or allow links. Beyond phishing, Link Shield can identify malware, scams, adult content, dating, gambling, crypto, and spam links, making it versatile for various use cases, especially where users can submit or share links within an app. It also supports bulk URL scoring and follows redirects and short links for comprehensive threat detection.

FAQs

What types of threats can Link Shield detect?

Link Shield can detect a wide range of threats beyond just phishing, including malware, scams, spammy destinations, risky adult or gambling links, and suspicious crypto pages. This comprehensive scanning helps protect users from various unwanted traffic within your product.

Does Link Shield follow redirects and short links?

Yes, Link Shield features redirect-aware scanning. It unwraps short links and follows redirect chains to uncover the final destination. This ensures that hidden destinations are surfaced, allowing for informed decisions rather than relying solely on the initial URL.

How does the risk score work, and what does it mean?

Each scan returns a risk score from 0 to 100, where lower scores indicate less suspicious behavior and higher scores suggest stronger warning signals. This score, combined with reason text, helps teams decide whether to allow a link silently, show a warning, queue it for review, or block it outright.

What is included in the free trial?

Link Shield offers a 5-day free trial. While the specific scan limits for the trial are not explicitly stated, it provides full access to the core protection features, real-time scoring, transparent signals, redirect chain analysis, and secure API keys to explore the API's capabilities.

Can I scan multiple URLs at once?

Yes, Link Shield supports bulk URL scoring. You can send batches of URLs in a single request and receive per-link risk scores back quickly. This feature is designed for efficiency when dealing with a high volume of links.
