Sourcevane Security CVE Intelligence
x402
Sourcevane Security CVE Intelligence is a paid API for AI agents from sourcevane-security-production.up.railway.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-12).
Returns a unified 0-100 priority score for a given CVE by aggregating CVSS severity, EPSS exploit probability, CISA KEV active-exploitation status, and OSV affected package data.

How this service works
Pay-per-call vulnerability intelligence for AI agents: CVSS (NVD) + exploit probability (EPSS) + active-exploitation status (CISA KEV) + affected packages (OSV), joined into a single 0-100 priority score, billed per call over x402.
Output
A JSON object containing the CVE identifier, a 0-100 numeric priority score, a priority band (e.g. CRITICAL), and a patch recommendation (e.g. patch_now), synthesized from CVSS, EPSS exploit probability, CISA KEV active-exploitation flag, and OSV affected package data.
Example use cases
Example prompt
“Give me the full vulnerability intelligence on CVE-2021-44228 — I need the combined priority score, whether it's actively exploited in the wild, its EPSS probability, and a patch recommendation so I know how urgently to act.”
Technical details
Endpoint
GEThttps://sourcevane-security-production.up.railway.app/v1/intel/cve/CVE-2021-44228?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, actionable priority score for a specific CVE that blends multiple authoritative data sources (NVD severity, real-world exploit probability, active exploitation confirmation, and affected packages) into one number — rather than querying NVD, EPSS, and CISA KEV separately and manually joining the data.
Side effects
- CVE identifier not found in NVD — returns error or empty result
- Malformed CVE ID format causes 400 bad request
- Upstream data sources (NVD, EPSS, CISA KEV, OSV) temporarily unavailable causing degraded or stale data
- Payment not processed via x402 — returns 402 Payment Required
- Rate limiting if called excessively
