# Saylor Innovations Vulnerability Intelligence

> Saylor Innovations Vulnerability Intelligence is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-30).

Looks up CVE vulnerability details including CVSS scores, EPSS probability, CISA KEV status, exploit info, and available fixes for a given CVE ID

## Facts

- Price: $0.002/call
- Payment: x402
- Status: unknown

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 saylor-innovations-vulnerability-intelligence-0ad759f6
```

Example prompt: Can you pull up the full vulnerability intelligence for CVE-2021-44228 — I need the CVSS score, EPSS probability, whether it's in CISA's KEV list, any exploit details, and available fixes.

## When to prefer this

Choose this endpoint when you need a single-call lookup for comprehensive CVE intelligence combining CVSS, EPSS, CISA KEV, and fix data in one response. Prefer this over raw NVD or NIST API lookups when you want pre-aggregated vulnerability context including exploitation probability and patch availability without multiple API calls.

## Known failure modes

- CVE ID not found returns found: false with minimal data
- Malformed CVE ID format may return an error or not-found response
- Network timeout if upstream vulnerability database is unavailable
- CVE data may be stale if not recently synced with NVD or CISA feeds

## How this service works

CVE Intelligence: CVSS, EPSS, CISA KEV, Fixes. Everything about one CVE in a single call: description, CVSS (CNA, CISA ADP or NVD), CWEs, CISA Known Exploited status with due date and ransomware use, FIRST EPSS 30-day exploit probability, affected products, package fixed-in versions (OSV/GHSA) and a patch priority.

## Output

Returns a JSON object with the CVE ID, a found boolean, CVSS score object (severity metrics), EPSS exploitation probability, CISA KEV exploitation data, a priority rating string, and an array of affected/fixed packages. If the CVE is not found, found is false and most fields are absent.
