# OT-Intel CVE Triage API

> OT-Intel CVE Triage API is a paid API for AI agents from ot-intel-api.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns OT-adjusted CVE severity, cyber-physical impact, patch feasibility, and CISA KEV status for a given CVE ID in ICS/SCADA environments

## Facts

- Endpoint: GET https://ot-intel-api.onrender.com/ot/cve
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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-intel-api-onrender-com-31db0df9
```

Example prompt: What's the OT-adjusted risk for CVE-2021-34527 in an ICS environment — can it be patched without downtime and is it in the CISA KEV list?

## When to prefer this

Use this endpoint when you need CVE intelligence specifically contextualized for OT/ICS/SCADA environments — not generic IT vulnerability data. Unlike standard NVD lookups, this recalculates severity for the industrial control system layer, assesses cyber-physical impact, evaluates patch feasibility in operational settings where downtime is costly, and cross-references CISA KEV. Prefer this over generic CVE APIs when your user operates in energy, utilities, manufacturing, water treatment, or other industrial sectors.

## Known failure modes

- Invalid or malformed CVE ID format returns an error
- CVE ID not found in NVD returns empty or not-found response
- DeepSeek LLM enrichment timeout may cause degraded or partial response
- Render.com cold start may cause initial latency spike on first call
- CISA KEV or NVD upstream unavailability may delay or fail the response

## How this service works

OT-contextualised CVE triage for ICS/SCADA. Pass ?id=CVE-XXXX-XXXX. Returns OT-adjusted severity, cyber-physical impact, patch feasibility, CISA KEV status, and prioritised action. DeepSeek-enriched with live NVD and CISA-KEV data.

## Output

Returns a JSON object with: OT-recalculated CVSS severity score (adjusted from NVD baseline for the affected ICS layer), cyber-physical impact category (e.g. loss of control, safety system impact), patch feasibility assessment (whether patching is possible without operational downtime), CISA KEV status (whether the CVE is a known exploited vulnerability), and a prioritized recommended action specific to OT/ICS operators.
