# SYS84 Wallet Risk Snapshot

> SYS84 Wallet Risk Snapshot is a paid API for AI agents from api.sys84.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Scores an EVM wallet address for on-chain risk, returning a risk score, risk level, verdict, and supporting signals for agent-driven access control decisions.

## 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 sys84-wallet-risk-snapshot-e292a52c -d '<json body>'
```

Example prompt: Can you run a risk snapshot on wallet 0x1234abcd...5678 on the Base chain and tell me whether it should be allowed, reviewed, or denied — I want the risk score and the reason codes too.

## When to prefer this

Choose this endpoint when you need a fast, per-call on-chain risk score for an EVM wallet address with structured verdict output (allow/deny/review) suitable for automated agent decision-making. It is well-suited for DeFi platforms, payment gateways, and compliance workflows that need machine-readable risk reason codes and on-chain signals like whale tier and token positions. Prefer this over generic blockchain explorers when you need a scored, actionable verdict rather than raw transaction history.

## Known failure modes

- Invalid or malformed EVM address returns an 'invalid' risk_level and a risk_score indicating unscoreable state
- Unsupported chain identifier may result in an error or fallback to Base chain behavior
- Payment failure via x402 protocol results in the call not being processed
- Upstream data unavailability may cause stale signals to be returned unless refresh=true is set
- Missing required address field returns a validation error

## How this service works

Cheap wallet risk snapshot for agents: score an EVM wallet before allowlisting, paying, routing, or trading with it. Returns risk score, verdict, reasons, and compact wallet signals.

## Output

Returns a JSON object containing: a numeric risk_score (0–100, higher means riskier), a risk_level string (minimal/low/medium/high/invalid), a verdict string (allow/allow_with_limits/review/deny), an array of machine-readable reason codes explaining the risk factors, and a signals object with supporting on-chain data including transaction count, token positions, whale tier classification, and safety flags.
