## 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 x402broker-com-base-evm-solana-smart-contract-security-scanner-2d97526d
```

Example prompt: Can you check if this Base contract 0x4200000000000000000000000000000000000006 is a honeypot and scan it for proxy patterns or other security risks before I interact with it?

## When to prefer this

Choose this endpoint when you need a quick, automated security pre-check on a Base EVM contract or Solana SPL Mint before interacting with it — especially for detecting honeypots, proxy upgrade risks, and freeze authorities in DeFi contexts. It is particularly useful for AI agents making autonomous on-chain decisions, trading bots, or any workflow that needs to gate transactions on contract safety. Prefer this over manual block explorer inspection when you need structured, machine-readable risk signals at low cost ($0.01/call).

## Known failure modes

- Invalid or malformed contract address returns an error
- Address not found on the Base or Solana network
- GoPlus API unavailable causes degraded results
- Rate limiting or payment failure (402) blocks the request
- Non-contract wallet addresses may return limited 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/smart-contract-audit)

## Output

Returns a structured security report for the given contract or mint address, including GoPlus honeypot detection results, proxy pattern identification, freeze authority status (for Solana), and overall risk indicators that help determine whether the contract is safe to interact with.
