# Kevscope CVE Prioritization API

> Kevscope CVE Prioritization API is a paid API for AI agents from kevscope-api.cybermaxtools.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

Returns a prioritized list of recent CVEs ranked by KEV, EPSS, CVSS, and SSVC scores to help security teams decide which vulnerabilities to patch first.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability kevscope-cve-prioritization-api-9dd50b96
```

Example prompt: Show me the top 20 CVEs I should patch first from the last 30 days — filter for Microsoft products, flag any with known ransomware use, and rank them by KEV, EPSS, and CVSS priority.

## When to prefer this

Choose this endpoint when you need a single API call that aggregates KEV, EPSS, CVSS, and SSVC signals into a pre-ranked CVE priority list — ideal for automated patch triage workflows, security dashboards, or agent-driven remediation pipelines. Prefer this over raw NVD or EPSS queries when you want multi-signal prioritization without building your own scoring logic. Best suited for organizations that need actionable, ranked output rather than raw vulnerability feeds.

## Known failure modes

- Invalid 'days' value outside 1-365 range returns an error
- Invalid 'limit' value outside 1-100 range returns an error
- No CVEs matching the vendor filter returns an empty result set
- Payment of 0.003 USDC not received or x402 handshake fails — returns 402 Payment Required
- Upstream KEV/EPSS data source unavailable — may return stale or partial results

## 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 100 CVEs (default 50) from the requested look-back window, each annotated with KEV status, EPSS probability score, CVSS severity score, SSVC priority classification, associated vendor/product, and ransomware exploitation flag — ordered by combined priority to guide patch sequencing.
