# CISA KEV Recent Additions Feed

> CISA KEV Recent Additions Feed is a paid API for AI agents from vuln-intel.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Returns CVEs added to the CISA Known Exploited Vulnerabilities (KEV) catalog within the last 1–90 days, sorted newest first, with vendor, product, due date, and ransomware-use flag.

## Facts

- Endpoint: GET https://vuln-intel.x402tookit.com/kev-recent?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_pIiRbsKV-RIkHrMgF6ujD

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 cisa-kev-recent-additions-feed-ef4e90f8
```

Example prompt: Show me all CVEs that CISA added to the Known Exploited Vulnerabilities catalog in the last 30 days, grouped by vendor so I can see who's been hit the most.

## When to prefer this

Use this endpoint when you need a time-bounded feed of newly catalogued actively-exploited CVEs from CISA, especially when you want vendor/product breakdowns and ransomware flags without querying individual CVEs. Prefer it over single-CVE lookup endpoints when monitoring for new threats across all vendors over a rolling window (up to 90 days). It is ideal for weekly security briefings, patch triage, and compliance reporting workflows.

## Known failure modes

- days parameter out of range (must be 1–90) returns validation error
- upstream CISA data temporarily unavailable causes empty or stale response
- payment not processed results in 402 response before data is returned
- network timeout if CISA feed is slow to respond

## How this service works

CVEs CISA added to the Known Exploited Vulnerabilities catalog in the last 1-90 days, newest first, with vendor and product.

## Output

A JSON object containing: total count of matching CVEs, timestamp of the data (asOf), a list of CVE records each with CVE ID, vulnerability name, vendor, product, date added, CISA remediation due date, and ransomware use classification, plus an aggregated byVendor breakdown, a human-readable summary, and an overall verdict on the threat landscape for the period.
