How this service works
Which CVEs to patch first, in one call. CVE priority API + MCP: KEV, EPSS, CVSS and SSVC, 20 CVEs per call Try it free in one click, no sign-up.
Output
A JSON list of up to 50 CVEs ranked by patch priority, each enriched with KEV (Known Exploited Vulnerability) status, EPSS exploitation probability score, CVSS severity score, and SSVC (Stakeholder-Specific Vulnerability Categorization) decision — giving a composite view for remediation triage in a single API call.
Example use cases
Weekly patch prioritization for security team
“Pull the top 25 vulnerabilities I need to patch this week, ranked by priority using KEV, EPSS, and CVSS — focus on CVEs from 2024 with an EPSS score above 0.2.”
Filtering actively exploited CVEs by year
“Show me the 2023 CVEs that are known to be actively exploited and have the highest chance of being used in attacks — limit to 10 and only show ones with EPSS above 0.5.”
Daily vulnerability triage for a SOC analyst
“Get me today's prioritized CVE watchlist — give me up to 50 results across all years, including their SSVC decisions and EPSS scores, so I can triage what needs immediate attention.”
Technical details
Endpoint
GEThttps://kevscope-api.cybermax-tools.workers.dev/x402/api/watchlist?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, opinionated call that combines multiple vulnerability scoring frameworks (KEV, EPSS, CVSS, SSVC) into one ranked watchlist — ideal for security teams automating patch prioritization workflows without having to query and join NIST NVD, CISA KEV, and FIRST EPSS separately. Prefer over raw NVD or EPSS APIs when you want pre-prioritized, actionable output rather than raw data.
Side effects
- Invalid year value returns an error or empty result set
- EPSS threshold out of 0-1 range may return an error
- Limit value outside 1-50 range may be rejected or clamped
- Payment not processed (x402 flow failure) returns 402 Payment Required
- Upstream data source (KEV/EPSS/CVSS) unavailable causes partial or failed response
