## 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 agent-kiosk-smart-contract-url-security-audit-1d8d6a85 -d '<json body>'
```

Example prompt: Can you run a security audit on this contract address 0x4200000000000000000000000000000000000006 on the Base network and tell me if it's safe to interact with?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call security audit of a specific smart contract address or URL without committing to a subscription. Ideal for agents that need on-demand contract safety checks before executing DeFi transactions, evaluating new protocols, or screening suspicious links. At $0.02 USDC per call via x402, it is cost-effective for spot checks across Base, Ethereum, BSC, Arbitrum, Polygon, and Optimism.

## Known failure modes

- Invalid or non-existent contract address returns error
- Unsupported blockchain network returns validation error
- Malformed URL target returns bad request
- Payment failure via x402 results in 402 response before audit runs
- Timeout if contract bytecode is very large or complex
- Rate limiting if too many calls made in succession

## How this service works

Pre-flight security scanner for 0x smart contracts/tokens (honeypot, tax, liquidity via GoPlus & DexScreener) and URLs (phishing & prompt injection).

## Output

Returns a JSON object with ok boolean and a data object containing security audit findings, which may include vulnerability classifications, risk scores, contract behavior analysis, and specific issues found in the smart contract or URL target.
