Evidence-backed facts

  1. The NVD Vulnerabilities API 2.0 exposes CVE records and NVD enrichment with identifiers, date windows, keyword, weakness, configuration, and severity filters. informative
  2. An API key is optional for lower-volume access and is recommended for sustained synchronization; keys are credentials and belong in headers rather than public assets. informative
  3. Clients should use modification windows, results-per-page, start index, backoff, and the published rate limits instead of repeatedly downloading the full collection. informative
  4. NVD enrichment and CVE source data can change or remain incomplete and do not prove exploitability, affected deployment, remediation success, or a complete risk assessment. informative
