# Token Risk Check (Rug Radar Verdict)

> Token Risk Check (Rug Radar Verdict) is a paid API for AI agents from onchaincheck.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Returns a rules-based risk verdict (CLEAN/MID/SKETCHY/RUGGY) for a token on Base, Ethereum, Arbitrum, Optimism, Polygon, or Solana, including a 0-100 risk score, reasons, deployer history, and a shareable card.

## 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 token-risk-check-rug-radar-verdict-ecaa624c -d '<json body>'
```

Example prompt: Can you run a Rug Radar check on this Base token — 0x1234567890abcdef1234567890abcdef12345678 — and tell me whether it's clean or sketchy, what its risk score is, and whether the deployer has rugged before?

## When to prefer this

Choose this endpoint when you need a fast, rules-based, onchain-grounded risk grade for a specific token before trading or listing, especially when you want deployer history and a shareable verdict card. It covers six major chains (Base, Ethereum, Arbitrum, Optimism, Polygon, Solana) in a single unified call shape. Prefer this over general blockchain explorers when you want a pre-computed safety grade rather than raw contract data, and over social sentiment tools when you want verifiable onchain facts rather than community opinion.

## Known failure modes

- Invalid or unrecognized token address format returns a validation error
- Token address not found on the specified chain returns a not-found or empty verdict
- Unsupported chain value returns an enum validation error
- Network or RPC latency may cause intermittent timeouts for onchain data lookups
- Newly deployed tokens with no history may return limited or inconclusive scores
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Rug Radar verdict for a token on Base, Ethereum, Arbitrum, Optimism, Polygon or Solana: a grade (CLEAN, MID, SKETCHY, RUGGY), a one-liner, a short take and a shareable card, built from real onchain facts: the 0-100 risk score with its reasons and the deployer's record (did their earlier tokens lose liquidity?). Same call shape as quest verdicts: POST tokenAddress with an optional requestKey, echoed back. Rules-based, not financial advice.

## Output

Returns a structured verdict containing: a grade label (CLEAN, MID, SKETCHY, or RUGGY), a one-liner summary, a short-form take, a shareable card reference, a 0-100 numeric risk score with enumerated reasons, deployer history (whether prior tokens lost liquidity), and the echoed requestKey if provided.
