NVD

The National Vulnerability Database (NVD) provides REST APIs for CVE (Common Vulnerabilities and Exposures) data, CPE (Common Platform Enumeration) records, match criteria, and source organizations. APIs deliver vulnerability descriptions, CVSS severity scores, affected product lists, CWE classifications, and reference links for security monitoring and dependency alerting.

NVD publishes 5 APIs on the APIs.io network, including CPE API, CPE Match API, CVE API, and 2 more. Tagged areas include Security, CVE, CPE, Vulnerability, and CVSS.

The NVD catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/nvd: open an issue to ask a question, or submit a pull request to add artifacts.
