## 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 fittings-cve-lookup-9f7c86e0
```

Example prompt: Can you look up CVE-2021-44228 and tell me what it describes, how severe it is, and where I can find more information about it?

## When to prefer this

Use this endpoint when you need a quick, structured lookup of a single CVE record from the official NVD, including its CVSS severity and references. Prefer this over the GitHub Advisory Database sibling endpoint (GHSA lookup) when you have a CVE ID and want authoritative NVD data rather than GitHub-specific enrichment like EPSS scores or CWE details. Ideal for triage workflows, dependency scan enrichment, and security ticket creation.

## Known failure modes

- CVE ID not found in NVD — returns an error or empty result
- Malformed CVE ID (e.g. missing 'CVE-' prefix) — returns a validation error
- NVD upstream unavailable — may return a timeout or 5xx error
- Very recent CVEs not yet indexed — record may not exist yet

## How this service works

A CVE record from the National Vulnerability Database: description, CVSS severity and references.

## Output

Returns the NVD CVE record for the requested identifier, including a plain-text description of the vulnerability, CVSS base score and severity rating, and a list of references (links to advisories, patches, or further information).
