ZeroWorker Security API
Prioritize up to 50 CVEs in one request using FIRST EPSS, CISA KEV, and known ransomware signals. Returns deterministic risk scores, urgency tiers, exploitation signals, vendor/product context, and remediation metadata as machine-readable JSON. Built for security automation and AI agents. No account or API key required. $0.01 per successful request via x402. Invalid input, no-signal results, and temporary resource failures do not settle.
