# Nomos Wallet Risk 360

> Nomos Wallet Risk 360 is a paid API for AI agents from base-agent-preflight.bytoken2023.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Returns a comprehensive 360-degree risk assessment for a blockchain wallet address, including risk score, risk level, flags, identity, and activity signals.

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 nomos-wallet-risk-360-420fd5c6 -d '<json body>'
```

Example prompt: Before I send that payment, can you run a full risk-360 check on the Ethereum wallet 0xAbC123...def on the ethereum chain and tell me the risk score and any red flags?

## When to prefer this

Choose this endpoint when an AI agent needs to make a pre-transaction risk decision about a specific blockchain wallet across Ethereum, Tron, or Bitcoin chains. It is particularly suited for autonomous agent execution-preflight scenarios where a structured risk score and flags are needed programmatically — rather than a human-readable compliance report. Prefer this over generic blockchain explorers when you need a structured risk_level enum, numeric risk_score, and AML flags in a single pay-per-request call without requiring a subscription.

## Known failure modes

- Missing required 'chain' or 'address' query parameters returns a validation error
- Invalid address format (too short or malformed) triggers schema rejection
- Unsupported chain value (not ethereum/tron/bitcoin) causes enum mismatch error
- Payment failure via x402 protocol results in 402 Payment Required before processing
- Unknown or unreachable address may return empty flags with low confidence
- Network timeouts on blockchain data lookups may cause slow or failed responses

## How this service works

Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.

## Output

A JSON object containing the network identifier (e.g. eip155:8453), product name, and an assessment object with risk_score (numeric), risk_level (e.g. 'low', 'medium', 'high'), and flags array. May also include identity, activity, and provenance sub-objects with enriched wallet intelligence.
