**Price:** 1 credit per 5000 results

**💡 AI Hint:** Get the NVD change-history log for vulnerabilities. Filter by a specific CVE id, a change date range, and/or a change event type (e.g. 'Initial Analysis', 'CVE Modified', 'Reanalysis', 'CVE Rejected'). Each record describes one change event with the source, timestamp and a list of detailed field-level changes (action, type, old value, new value).
