# OT/ICS Vendor Supply-Chain Risk Assessment

> OT/ICS Vendor Supply-Chain Risk Assessment is a paid API for AI agents from ot-intel-api.onrender.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-14).

Returns a risk tier, confidence score, cited CVEs (KEV/EPSS), threat actor targeting history, and supply-chain mitigation recommendations for a named OT/ICS vendor and optional product line.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ot-ics-vendor-supply-chain-risk-assessment-fc421673
```

Example prompt: Can you pull a supply-chain vendor risk assessment for Schneider Electric, specifically the Modicon product line — I need the risk tier, any KEV or EPSS-cited CVEs, which threat actors have historically targeted them, and recommended mitigations?

## When to prefer this

Use this endpoint when you need a synthesized, intelligence-grade OT/ICS supply-chain risk profile for a named vendor — especially when you need CVE citations (KEV/EPSS), threat actor attribution, and mitigation guidance in ICD-203 language in a single call. Prefer this over generic vulnerability databases when OT/ICS-specific context and supply-chain framing are required.

## Known failure modes

- Missing vendor parameter returns an error indicating at least one query param is required
- Unknown or obscure vendor name may return low-confidence result or empty threat actor list
- Payment failure (402) if x402 USDC payment is not successfully processed before the request
- Vendor name misspelling may result in no match or incorrect vendor being assessed
- Rate limiting or service unavailability from the Render-hosted backend

## How this service works

OT/ICS supply-chain vendor risk assessment. Pass ?vendor=(name) e.g. Schneider Electric, Siemens, Rockwell Automation, optionally &product=(line) e.g. Modicon. Returns risk tier, confidence, cited CVEs (KEV/EPSS), threat actors with historical targeting interest, and supply-chain mitigation recommendations. DeepSeek-synthesised, ICD-203 language. Certain restricted-license sources excluded.

## Output

A structured report containing: a risk tier classification for the vendor (and optionally the product line), a confidence score for the assessment, a list of cited CVEs tagged with KEV and EPSS scoring, known threat actor groups with documented historical interest in targeting that vendor or product line, and prescriptive supply-chain mitigation recommendations — all written in ICD-203 intelligence language.
