# Macaroon Network NVD CVE Full Corpus Search

> Macaroon Network NVD CVE Full Corpus Search is a paid API for AI agents from api.macaroonnetwork.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Search the complete 100,000-record NVD (NIST) CVE corpus by keyword, returning CVE descriptions, CVSS base scores, and CVSS base severity ratings.

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 macaroon-network-nvd-cve-full-corpus-search-809e3b13 -d '<json body>'
```

Example prompt: Search the full NVD CVE corpus for vulnerabilities related to Apache Log4j and show me the CVE IDs, descriptions, CVSS base scores, and severity ratings.

## When to prefer this

Choose this endpoint when you need broad coverage across the full NVD CVE corpus (100,000+ records) and do not require CISA Known Exploited Vulnerabilities (KEV) cross-referencing. Prefer this over the smaller cve-search-v1 listing when you need comprehensive NVD coverage beyond the five-keyword KEV-filtered sample. Ideal for vulnerability research, dependency audits, and threat intelligence workflows that require the widest possible CVE dataset.

## Known failure modes

- No matching CVEs found for the query — returns empty results
- Overly broad query returns too many records — may require refinement
- Query string not provided or malformed body — returns 400 or validation error
- Service temporarily unavailable — returns 5xx error
- Payment not processed — x402 payment required response

## How this service works

Search the full 100,000-record NVD (NIST) CVE corpus -- description, CVSS base score, and CVSS base severity, harvested directly from the NVD API and confirmed public domain. This is the complete harvested corpus, distinct from the smaller 1,765-record cve-search-v1 listing, which draws from a five-keyword sample cross-referenced with the CISA Known Exploited Vulnerabilities list; that KEV cross-reference is not part of this corpus.

## Output

Returns matching CVE records from the 100,000-record NVD corpus, each including the CVE identifier, human-readable description, CVSS base score (numeric), and CVSS base severity label (e.g. CRITICAL, HIGH, MEDIUM, LOW). This is the full harvested NVD corpus, not the smaller KEV-cross-referenced subset.
