## 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 speer-cyber-defense-kev-security-news-feed-a09b22fb
```

Example prompt: Pull the latest 20 entries from the Known Exploited Vulnerabilities security news feed so I can see which vulnerabilities are actively being exploited right now.

## When to prefer this

Choose this endpoint when you need structured, up-to-date Known Exploited Vulnerabilities news data via a pay-per-call micropayment API without requiring a subscription. Ideal for AI agents that need real-time KEV threat intelligence on demand with minimal cost ($0.001 USDC per call) and automatic non-billing on failures.

## Known failure modes

- HTTP 402 if USDC payment via x402 is not provided or insufficient
- HTTP 503 if the underlying KEV feed source is unavailable (not billed)
- Empty items array if no KEV entries are currently available
- Invalid limit parameter returns unexpected result counts

## How this service works

Cybersecurity micropayments API for AI agents — pay-per-call USDC on Base and Solana (x402 v2). Free utility services under /v1/free/* and gateway select under /v1/gateway/* (Public). Paid cybersecurity analysis, CVE/security news feeds, Base blockchain intelligence, network intel utilities, composite domain/URL reports, research, conversion, verification, and feeds. Failed security analyses are not billed (HTTP 503).

## Output

Returns a JSON object with a boolean ok field, a status string, an updatedAt ISO datetime indicating when the feed was last refreshed, and an items array containing KEV news entries representing known exploited vulnerabilities currently tracked by CISA or equivalent authorities.
