## 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 x402-audit-agentdiet-dev-base-evm-solana-smart-contract-security-fb1d9356
```

Example prompt: Can you security-scan the Base contract at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed and tell me if GoPlus flags it as a honeypot, whether it uses a proxy pattern, and if there are any freeze authority concerns?

## When to prefer this

Choose this endpoint when you need quick, on-demand security screening of a specific Base EVM contract or Solana SPL mint before interacting with it — especially for honeypot detection, proxy pattern analysis, and freeze authority checks. Prefer this over generic block explorers when you need structured, machine-readable risk flags from GoPlus rather than raw on-chain data.

## Known failure modes

- Invalid or malformed address returns an error or empty result
- Unsupported chain or address format (non-Base EVM, non-Solana SPL) may return no data
- GoPlus data unavailable for very new or obscure contracts
- Payment failure (x402) if USDC funds are insufficient
- Rate limiting or timeout if the upstream GoPlus API is slow

## 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://x402-audit.agentdiet.dev/v1/smart-contract-audit)

## Output

Returns a structured security report including proxy pattern detection results, GoPlus honeypot flags, freeze authority status, and overall risk indicators for the queried contract or SPL mint address
