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-priority-api-366f59f5
```

Example prompt: Can you tell me which of these CVEs I should patch first: CVE-2021-44228, CVE-2023-44487, CVE-2024-3400, CVE-2022-26134, and CVE-2023-23397? Give me the full details including affected products.

## When to prefer this

Use this endpoint when you need to quickly triage a list of CVEs by actual exploitability and real-world threat data rather than CVSS alone. Ideal for security operations, patch management workflows, and compliance reporting where prioritization across KEV, EPSS, CVSS, and SSVC dimensions is required in a single API call. Prefer this over manual NIST NVD lookups or separate EPSS queries when you need consolidated, actionable patch priority in one step for up to 20 CVEs.

## Known failure modes

- Invalid CVE ID format returns error or empty result for that entry
- More than 20 CVEs submitted may result in truncation or rejection
- Network timeout if the upstream NVD or EPSS data sources are slow
- Unrecognized or very new CVEs may return incomplete scoring data
- Payment failure (402) if USDC balance is insufficient

## 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 response containing each CVE's patch priority ranking derived from combined KEV (Known Exploited Vulnerabilities) catalog status, EPSS (Exploit Prediction Scoring System) probability, CVSS severity score, and SSVC (Stakeholder-Specific Vulnerability Categorization) decision. Optionally includes full vulnerability descriptions and lists of affected products.
