## 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-scanner-x402-pay-per-call-bc8e8faa
```

Example prompt: Can you scan this Ethereum contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and tell me whether it has any on-chain risk signals I should know about before I buy?

## When to prefer this

Choose this endpoint when you need a fast, permissionless, pay-per-call on-chain risk scan for a specific token or smart contract without requiring an account or KYC. It is ideal for DeFi agents, portfolio managers, or trading bots that need to gate decisions on token safety before executing swaps or investments. Prefer it over subscription-based alternatives when you want to pay only for the calls you make in USDC on Base via the x402 protocol.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unsupported or unrecognized chain name may return an error or empty result
- Contract address not found on the specified chain returns no data
- Payment failure via x402 results in 402 response and no risk data
- Rate limiting or infrastructure issues on the bare-IP host may cause timeouts

## How this service works

Static on-chain token/contract risk scan (bytecode heuristics).

## Output

Returns a risk assessment for the specified token or smart contract, including risk signals, potential red flags (e.g. honeypot patterns, ownership concentration, malicious code indicators), and an overall risk level for the contract on the given chain.
