How this service works
CVE lookup by id or NVD keyword search (severity, days, maxItems): CVSS v3.1/v4 score+vector, CWE, affected products, references, CISA KEV status, EPSS score and a patch priority line.
Output
Returns a JSON object with timestamp, total count, and an array of CVE items. Each item includes the CVE ID, CVSS v3.1/v4 score and vector, severity, CWE IDs, list of affected products (CPE), CISA KEV details (vendor, product, due date, ransomware use), EPSS score and percentile, publication and last-modified dates, references, vulnerability description, and a human-readable patch priority recommendation line.
Example use cases
Critical CVE triage for incident response
“We just heard Log4Shell is being actively exploited — look up CVE-2021-44228 and give me the CVSS score, CWE, CISA KEV status, EPSS score, and the patch priority recommendation so I know how fast to act.”
Weekly critical vulnerability digest
“Find me up to 20 critical-severity CVEs published in the last 7 days and summarize their patch priority so I can decide what to escalate to my security team this week.”
Vendor-specific vulnerability research
“Search for CVEs related to 'Citrix NetScaler' with high or critical severity from the past 30 days — I need CVSS scores, affected versions, and whether any are in CISA KEV.”
Technical details
Endpoint
GEThttps://cve.genexxis.com/cve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, enriched vulnerability data combining NVD, CISA KEV, and EPSS in a single call with a human-readable patch priority signal — especially when triaging whether to patch immediately. Prefer over raw NVD API access when you want pre-joined KEV and EPSS data without assembling multiple sources yourself. Ideal for agents doing automated vulnerability triage, security reporting, or compliance checks.
Side effects
- CVE ID not found in NVD — returns empty result set
- Invalid CVE ID format — may return no results or error
- Keyword search returns 0 results if no NVD entries match all words
- days parameter out of range (>120) may be rejected or clamped
- maxItems exceeding 50 ignored or capped at 50
- NVD API upstream outage causes downstream failure
- Payment not processed — x402 payment required error
