# Selun SCE Risk Evaluate

> Selun SCE Risk Evaluate is a paid API for AI agents from selun.sagitta.systems, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-15).

Performs doctrine-based risk evaluation of a DeFi protocol or smart contract execution preflight, returning a risk level, risk score, domain-specific warnings, and a recommended action (e.g. BLOCK/PAUSE) for autonomous agents.

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 selun-sce-risk-evaluate-70e7a5aa -d '<json body>'
```

Example prompt: Before we execute that rebalance on the Aave protocol on chain 1, run a Sagitta SCE risk evaluation against addresses 0xabc...123 and 0xdef...456 with a moderate risk tolerance, checking for oracle and bridge threat families, and tell me if doctrine says we should block or proceed.

## When to prefer this

Use this endpoint when an autonomous agent needs a doctrine-gated, multi-domain risk verdict before executing any on-chain action against a DeFi protocol — especially when threat families, governance risk, or bridge/oracle exposure are relevant. Prefer over generic risk APIs when you need Sagitta SCE's structured reason codes, continuity mode, and recommended next-step routing built for agentic execution preflight.

## Known failure modes

- Payment not received or insufficient USDC — 402 response blocking access
- Invalid or missing chain_id — 400 validation error
- Unknown protocol_name or unresolvable addresses — low-confidence result or error
- Doctrine tag not recognized — evaluation proceeds without doctrine filter
- Pipeline degraded — confidence label drops to 'low' with partial results
- Expired evaluation — valid_until exceeded, agent must re-call

## How this service works

Protocol risk gate. Returns `doctrine_action` (BLOCK | ALLOW | ESCALATE), `risk_level`, `risk_score`, and per-domain `risk_domains`. If doctrine_action === BLOCK, halt the action and return `reason_codes` and `recommended_next` to the user. Recheck after `valid_until`. Call this when continuity-mode returns mode !== NORMAL or recommended_posture is require_review or pause.

## Output

Returns a JSON object with a risk_level (e.g. HIGH), numeric risk_score (0-100), confidence label and score, doctrine_action (BLOCK/PAUSE/PROCEED), per-domain risk ratings (bridge, oracle, governance, treasury, etc.), continuity mode and recommended posture, reason codes explaining the verdict, a validity timestamp, and a pointer to the recommended next SCE endpoint (e.g. escalation-brief) if action is blocked.
