## 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 hexscan-smart-contract-risk-scanner-73fef571 -d '<json body>'
```

Example prompt: Before I buy this token, can you scan contract address 0x1234...abcd on Ethereum for honeypot traps, hidden taxes, and whether the source code is verified?

## When to prefer this

Choose this endpoint when you need fast, automated pre-trade risk triage for a smart contract — especially honeypot detection and tax analysis — before a DeFi swap or investment decision. It is best for quick go/no-go signals rather than comprehensive audits. Prefer this over manual block explorer checks when operating in an automated or agentic DeFi workflow.

## Known failure modes

- Invalid or unrecognized contract address returns an error
- Unsupported chain name causes a 400-level error
- Unverified or very new contracts may have limited analysis data
- Proxy contracts may only analyze the proxy, not the implementation
- Rate limit or payment failure returns 402 or 429 status

## How this service works

Is this token safe to buy? Honeypot detection, rug-pull and scam check for any ERC-20 token contract -- flags can't-sell traps, hidden mints, malicious buy/sell taxes, unverified source, and holder concentration. GoPlus-powered token security scan with risk score 0-100. Not an audit.

## Output

Returns a risk triage report including whether the contract exhibits honeypot behavior (prevents selling), buy and sell tax percentages, source code verification status, and any detected risk flags or anomalies. Not a full security audit but covers the most critical red flags.
