How this service works
Newly published CVEs from the NVD since a timestamp, scored 1-10 by CVSS base severity, with descriptions and links. Filter with ?min_significance=7 for high/critical only.
Output
A JSON object containing a count of matched CVEs, a source label, and an array of change objects each with CVE ID (entityId), title, summary, detail object, CVSS-based significance score (1-10), detected-at datetime, effective date, change type, and a primary-source URL linking to the NVD entry for verification.
Example use cases
Example prompt
“Pull all new CVEs from the NVD published since 2025-06-01T00:00:00Z with a CVSS significance score of at least 7, up to 100 results — I want to review the high and critical ones for our security report.”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/cve/changesWhen to prefer
Choose this endpoint when you need a structured, scored, pageable feed of newly published NVD CVEs since a specific timestamp, especially when you want to filter to only high/critical severity using min_significance. Prefer over raw NVD API polling when you want a normalized, pre-scored output with direct source links, or when integrating into an automated security monitoring workflow that pays per query.
Side effects
- Missing or malformed 'since' date-time returns validation error
- min_significance or limit outside allowed range (1-10 / 1-500) returns 400
- NVD upstream unavailable causes 502 or stale data
- No CVEs match the filter window — returns empty changes array with count 0
- Payment not provided or insufficient — returns 402 Payment Required
