How this service works
AgentAegis cve_lookup — CVSS score, severity, CWE classifications, CISA KEV (known-exploited) status, affected products and references for a CVE id. NVD with CIRCL + OSV fallback for reliability.
Output
Returns a structured record containing the CVE ID, CVSS v3 score (e.g. 10.0), severity label (e.g. CRITICAL), CWE classification identifiers, a boolean indicating CISA KEV known-exploited status, a list of affected products, and reference URLs — sourced from NVD with CIRCL and OSV as fallbacks.
Example use cases
Example prompt
“Can you look up CVE-2021-44228 and tell me its CVSS v3 score, severity level, whether it's on the CISA known-exploited list, and which products are affected?”
Technical details
Endpoint
POSThttps://agentaegis-mcp-production.up.railway.app/x402/cve-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, multi-source vulnerability metadata for a specific CVE ID — especially when you need CISA KEV known-exploited status alongside CVSS scoring and CWE classification in a single call. Prefer this over raw NVD queries when reliability matters, since it falls back to CIRCL and OSV automatically.
Side effects
- CVE ID not found in NVD, CIRCL, or OSV — returns error or empty result
- Malformed CVE ID format — returns validation error
- All upstream data sources (NVD, CIRCL, OSV) temporarily unavailable — returns service error
- CVE exists but has incomplete scoring data — partial result returned
