Overview

Scanii is a cloud-based malware scanning API that accepts file uploads and returns a verdict on whether the file contains threats. It supports documents, images, archives, and executables, making it practical for user upload pipelines on web applications. Beginners can use it to prevent malicious files from being stored on their servers.

💡

Beginner Tip

Sign up at scanii.com for a free trial key. Authenticate using HTTP Basic Auth with your API key as the username and an empty string as the password — do not put the key in a header.

  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);

Common Errors & Troubleshooting

401 Unauthorized API credentials are missing or the Basic Auth format is incorrect
✓ Use -u "YOUR_API_KEY:" in curl (note the colon with no password); in code, set username to your key and password to empty string
413 Payload Too Large The uploaded file exceeds the maximum allowed size for your plan
✓ Check your plan limits at scanii.com; free tier supports files up to 20 MB
pending status in response Large files are processed asynchronously and are not immediately ready
✓ Use the id from the initial response to poll GET /v2.1/files/{id} until the status changes from pending to done
