What It Does

ArkAPI CVE Lookup returns a clean JSON view of a specific CVE. It is designed for bots, analysts, and reporting pipelines that need direct vulnerability context without scraping advisory pages or wiring up multiple upstream sources.

Severity, CVSS, and CWE context
Published and modified dates
Known Exploited Vulnerability signal when available
Reference links for follow-up analysis

Result Shape

The response is designed for triage and reporting, not just raw storage. ArkAPI surfaces the fields that matter most when an agent or analyst needs to quickly decide whether a vulnerability deserves attention.

severity and cvss_score for fast prioritization
cwe for weakness classification
kev when the issue appears in the Known Exploited Vulnerabilities list
references for vendor or analyst follow-up
