Microsoft Security Response Center (MSRC) API
Overview
The Microsoft Security Response Center (MSRC) API provides programmatic access to Microsoft's security update data, including CVEs, advisories, and patch information. It is free to use without authentication and is ideal for organizations that need to track Microsoft vulnerabilities for patch management or compliance. The data is published in CVRF (Common Vulnerability Reporting Framework) format.
Beginner Tip
No API key is required — you can start querying immediately. Use the /Updates endpoint to list all available security updates, then fetch a specific update by its ID (formatted as YYYY-MMM, e.g., 2024-Jan) to get full CVE details.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.
{
"url": "https://example.com",
"safe": true,
"threat_level": "none",
"categories": [
"clean"
],
"scan_date": "2025-01-15T10:00:00Z"
} Field Reference
DocumentTitle.Value Title of the security update document (e.g., "January 2024 Security Updates"). Vulnerability Array of CVE entries included in this security update. Vulnerability[].CVE CVE identifier for the vulnerability (e.g., CVE-2024-12345). Vulnerability[].Threats Threat assessment entries including severity and impact type. Vulnerability[].Remediations Patch and workaround information including KB article numbers. Implementation Example
Calls a real endpoint of this API. Replace any placeholder credentials with your own key.
const url = "https://api.msrc.microsoft.com/cvrf/v3.0/Updates";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
