CISA Industrial Control Systems (ICS) advisories — vulnerabilities in operational-technology gear (SCADA, PLCs, building automation, energy/manufacturing/transportation systems, and medical devices), from the official CISA advisory RSS feed. Each item is normalized to the canonical advisory id (ICSA-YY-DDD-NN, or ICSMA-YY-DDD-NN for medical), title, link to the full advisory, publication date (ISO), and a plain-text summary. Optionally filter by keyword (e.g. a vendor like "Siemens") and cap the count. Returned newest-first. Free, public-domain (CISA).
/api/security/ics-advisoriesPAYMENT-SIGNATURE.The ics advisories API is a pay-per-call security endpoint built for AI agents and autonomous software. CISA Industrial Control Systems (ICS) advisories — vulnerabilities in operational-technology gear (SCADA, PLCs, building automation, energy/manufacturing/transportation systems, and medical devices), from the official CISA advisory RSS feed.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in ics advisories data source for an agent tool-use loop, an MCP host, or a backend that needs security data on demand without onboarding to yet another vendor portal.
