## 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-ec667bfa
```

Example prompt: Can you scan the Base EVM contract 0x4200000000000000000000000000000000000006 for honeypot flags, proxy patterns, and any other security risks before I interact with it?

## When to prefer this

Choose this endpoint when you need automated, on-chain security screening of a specific Base EVM contract or Solana SPL Mint before trading, investing, or interacting with it — especially when you need GoPlus honeypot intelligence combined with proxy pattern and freeze authority checks in a single call. Prefer this over manual block explorer review when building DeFi agents or investment screening workflows that require programmatic risk signals.

## Known failure modes

- Invalid or malformed address returns an error indicating unrecognized address format
- Contract address not found on Base or Solana returns empty or not-found result
- GoPlus API unavailability may cause incomplete honeypot flag data
- Rate limiting or payment failure (HTTP 402) if x402 payment is not processed
- 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://x402-audit.agentdiet.dev/v1/bytecode-scanner)

## Output

Returns a structured security report for the given contract or mint address, including proxy pattern detection results, GoPlus honeypot flags, freeze authority status (for Solana), and an overall risk assessment of the smart contract.
