# Stack Facts CVE Prioritize

> Stack Facts CVE Prioritize is a paid API for AI agents from g5joilnmeep4ntz3nwezxt5dmu.srv.us, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Ranks a list of CVE identifiers by exploitability and severity, flagging CISA KEV membership, ransomware association, CVSS scores, and remediation due dates.

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 stack-facts-cve-prioritize-43b05317 -d '<json body>'
```

Example prompt: Can you prioritize these CVEs for me — CVE-2021-44228, CVE-2022-26134, and CVE-2023-23397 — and tell me which ones are in the CISA KEV catalog, whether any are linked to ransomware, and what their remediation deadlines are?

## When to prefer this

Choose this endpoint when you need to triage multiple CVEs by real-world exploitability rather than just CVSS score alone — particularly when KEV membership, ransomware linkage, and mandatory remediation deadlines (CISA due dates) are decision factors. It is ideal for security automation pipelines, pre-deployment gates, or any agent workflow where patch priority must be justified by authoritative government threat data. Prefer it over raw NVD or OSV lookups when you want a single ranked, signed answer combining KEV and CVSS in one call.

## Known failure modes

- Invalid CVE format (must match CVE-YYYY-NNNNN pattern) returns validation error
- Empty or missing cves array returns error
- More than 100 CVEs in a single request exceeds maxItems limit
- CVE not found in any dataset returns entry with null scores and no KEV data
- Payment failure or insufficient USDC balance blocks the request
- Stale dataset flag in meta indicates data may be behind the latest KEV catalog

## How this service works

Check a package before install: malware, known vulnerabilities (OSV), exploited CVEs (CISA KEV) and end-of-life, plus LLM prices; signed answers, pay per call in USDC, no account or API key.

## Output

Returns a ranked list of CVEs ordered by priority (KEV membership first, then CVSS score descending), each entry including rank, CVSS score, KEV membership flag, ransomware association, KEV due date, KEV date added, priority label (e.g. critical), and priority basis. Also includes aggregate counts, KEV catalog version, dataset attribution, and license links.
