# 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 2026-10-03).

Returns actively exploited vulnerabilities from the CISA Known Exploited Vulnerabilities (KEV) catalog enriched with EPSS exploitation probability scores

## Facts

- Endpoint: GET https://saylorinnovations.com/api/vuln/kev?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-03
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/saylor-innovations-vulnerability-intelligence-ad463127
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_LA1lcHNIVaN-OmcZd97vv

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-ad463127
```

Example prompt: Pull the actively exploited vulnerabilities from the CISA KEV catalog that were added in the last 14 days and show me their EPSS scores so I can prioritize patching.

## When to prefer this

Choose this endpoint when you need a combined view of actively exploited vulnerabilities (CISA KEV) cross-referenced with EPSS exploitation probability scores in a single call. Prefer it over raw CISA KEV or EPSS APIs when you want pre-joined threat intelligence without building your own enrichment pipeline. Ideal for security automation, patch prioritization workflows, or agent-driven vulnerability triage.

## Known failure modes

- Invalid 'days' query parameter value may result in an error or default fallback behavior
- Network or upstream CISA KEV data source unavailability could cause stale or empty results
- Very large day windows may return very large payloads
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Actively Exploited Vulnerabilities (CISA KEV + EPSS) — Security

## Output

Returns a JSON object containing the total number of matches, the current KEV catalog version, and an array of vulnerability objects. Each vulnerability entry includes CVE identifiers, vulnerability details, and EPSS exploitation probability scores for the vulnerabilities added to the CISA KEV catalog within the specified time window (default 30 days).
