# OT/ICS Remediation Action Conformance Gate

> OT/ICS Remediation Action Conformance Gate is a paid API for AI agents from ot-intel-api.onrender.com, paid per call via x402, $0.12/call, status unknown (last checked 2026-09-14).

Evaluates a planned OT/ICS remediation action (e.g. block_ip, quarantine_host) against threat intelligence scoring rules and returns an auto_approve, human_review, or reject decision without LLM involvement.

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-remediation-action-conformance-gate-4b8ca631
```

Example prompt: Before I block the domain linked to SANDWORM activity targeting the energy sector in the GCC region, can you run a conformance check on that block_domain action — the asset is sitting behind shared Cloudflare infrastructure — and tell me whether it's auto-approved, needs human review, or should be rejected?

## When to prefer this

Use this endpoint when an automated OT/ICS incident response workflow needs a deterministic, auditable go/no-go gate before executing a remediation action — especially when regulatory compliance or shared infrastructure risk requires a human-in-the-loop check. Prefer this over LLM-based judgment or generic SOAR rules when the decision must be explainable and reproducible, and when you need sector/region/actor-specific risk context baked into the approval logic.

## Known failure modes

- Missing required parameters (actor, sector, region, planned_action) returns 400 with validation error
- Unknown or unsupported planned_action enum value returns 400
- Actor name not recognized in threat intelligence database may return low-confidence or default scoring
- Render.com cold-start latency on first request may cause timeout
- Payment failure or missing x402 header returns 402 Payment Required
- asset_context with unrecognized shared infra tags may not trigger escalation logic

## How this service works

Deterministic remediation risk gate. Pass actor, sector, region, planned_action (e.g. block_ip, halt_pipeline, disable_account). Returns auto_approve/human_review/reject via capability x opportunity x intent scoring (same as /ot/threat-score) — no LLM in the loop. auto_approve requires vendor_stack; omitting it caps the verdict at human_review regardless of score. Optional asset_context escalates to human_review on shared cloud/CDN infra (e.g. shared_infra:cloudflare).

## Output

Returns a structured conformance verdict — one of auto_approve, human_review, or reject — derived from deterministic capability x opportunity x intent scoring rules. Includes the rationale for the decision, any escalation triggers (e.g. shared CDN/cloud infrastructure detected via asset_context), and an auditable rule trace with no LLM in the decision path.
