Verisys Antivirus API

About Verisys Antivirus API

Verisys Antivirus API is a REST API that scans uploaded files and file URLs for viruses and malware, returning a status, detected signals, and file metadata such as content type and SHA1 hash. It also offers NSFW image scanning that classifies images for inappropriate content, and file content type detection that inspects file contents to identify the true format among more than 90 supported file types, guarding against file type spoofing via mismatched extensions or Content-Type headers.

The API is language-agnostic and supports both synchronous and asynchronous scanning, with webhook notifications for completed async scans, and code samples are provided in JavaScript, C#, Java, Python, Go, Ruby, Rust, PHP, and PowerShell. It operates from four global regions (United States, Europe, United Kingdom, and Asia Pacific), encrypts data in transit with TLS and at rest with AES-256, and states GDPR compliance.

It is intended for developers who need to scan user-generated content and file uploads before they reach applications, servers, or end users. Plans are billed monthly or annually based on scan volume: Starter (1,000 scans/month, $39/month), Pro (5,000 scans/month, $79/month), Premium (15,000 scans/month, $199/month), and a customizable Enterprise tier with dedicated clusters and priority support. All plans include commercial-grade malware scanning, NSFW scanning, multi-region availability, and a 99.97% uptime guarantee. A free trial is available.
