## 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 broker-solidity-audit-smart-contract-security-scanner-eb01cd32
```

Example prompt: Can you audit the Base EVM contract at 0x1234567890abcdef1234567890abcdef12345678 for honeypot risks, proxy patterns, and any other on-chain security red flags before I interact with it?

## When to prefer this

Use this endpoint when you need a quick, paid ($0.01 USDC) automated security scan of a specific Base EVM or Solana contract before interacting with it — especially when you want honeypot detection via GoPlus, proxy pattern analysis, and freeze authority checks in a single call without setting up your own security infrastructure.

## Known failure modes

- Invalid or malformed contract address returns an error
- Address not found on Base EVM or Solana returns no data
- GoPlus API unavailability may affect honeypot detection results
- Unsupported chain or address format causes a rejection
- Newly deployed contracts with no on-chain history may return incomplete results

## How this service works

Audits any Base EVM 0x contract or Solana SPL Mint for proxy patterns, GoPlus honeypot flags, and freeze authority. (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/solidity-audit)

## Output

Returns a structured security report including whether the contract uses proxy patterns, GoPlus honeypot detection flags, freeze authority status (for Solana SPL mints), and an overall on-chain risk assessment for the queried address.
