## 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 cve-vulnerabilities-search-api-f660308c
```

Example prompt: Search the CVE vulnerabilities database for any known security vulnerabilities related to 'log4j' and show me what comes back.

## When to prefer this

Use this endpoint when you need quick, pay-per-use CVE vulnerability lookups by keyword without subscribing to a full NVD or vulnerability intelligence platform. Ideal for agent workflows that need on-demand security data at low cost ($0.01/call) via x402 micropayment protocol.

## Known failure modes

- Missing required 'keyword' parameter returns validation error
- Keyword with no matching CVEs returns empty results
- Payment failure via x402 protocol blocks request
- Service unavailability on Railway deployment
- Very broad keywords may return truncated or rate-limited results
