How this service works
Agent-native cybersecurity intelligence. Real OSV + EPSS + KEV data. Stack briefs, dep audits, advice, web reconnaissance. Prioritized for autonomous builders and harnesses.
Output
Returns a timestamped response containing an array of vulnerability records enriched with EPSS exploit probability scores and CISA KEV membership flags, plus a list of data sources consulted (OSV, EPSS, KEV) and a unique query ID for traceability.
Example use cases
Triage critical dependency vulnerability
“I need to check CVE-2021-44228 (Log4Shell) — what's its current EPSS score and is it in the CISA KEV list? Show me up to 10 related results.”
Audit stack for high-exploit-risk CVEs
“Find me all vulnerabilities with an EPSS score above 0.7 that are in the Known Exploited Vulnerabilities catalog — limit to the top 20 most dangerous ones so I can prioritize patching.”
Discover exploitable CVEs for a software package
“Search for known vulnerabilities in OpenSSL and filter to only show ones that are on the CISA KEV list — I want to know what's actively being exploited in the wild.”

Endpoint
POSThttps://synthr.online/v1/cyber/vulnsWhen to prefer
Choose this endpoint when you need real-time, multi-source vulnerability intelligence that combines OSV CVE data with EPSS exploit probability AND CISA KEV status in a single call. Prefer it over generic CVE databases when you need exploit-prioritized triage rather than raw vulnerability listings, or when building autonomous security workflows that need structured, machine-readable threat intelligence without manual lookups.
Side effects
- CVE not found — returns empty results array
- Invalid CVE format — may return error or empty results
- minEpss value out of 0-1 range — may be rejected or ignored
- Upstream OSV/EPSS/KEV data unavailable — stale or partial results returned
- Rate limit or payment failure — 402 payment required error
