How this service works
CVE lookup / vulnerability database. NIST NVD-backed. CVSS v3.1 + v2 scores, severity, affected CPEs, CWE class, references, public-exploit indicators. Plus LLM exploitability summary.
Output
Returns the full NVD record for the requested CVE including CVSS v3.1 and v2 base scores, severity label (Critical/High/Medium/Low), list of affected CPEs, CWE classification, reference URLs, a boolean/indicator for whether a public exploit is known, and an LLM-generated plain-English summary of the vulnerability's exploitability.
Example use cases
Example prompt
“Can you look up CVE-2021-44228 (Log4Shell) and tell me its CVSS v3.1 score, severity, which products are affected, whether there's a known public exploit, and give me an AI summary of how exploitable it is?”

Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/cve-lookupWhen to prefer
Use this endpoint when you need structured, authoritative vulnerability data including CVSS scores, CPE impact scope, CWE class, and exploit availability — especially when you also want an LLM-generated exploitability summary in a single call. Prefer over raw NVD API calls when you need enriched, agent-ready output with payment handled via x402.
Side effects
- CVE ID not found in NVD — returns error or empty result
- Malformed CVE ID format — returns validation error
- NVD upstream unavailable — service error or timeout
- CVE too recent to be indexed — partial or missing data
- Payment failure — request rejected before processing
