## 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-83a122cf
```

Example prompt: Can you scan this Base contract 0x4200000000000000000000000000000000000006 for honeypot flags, proxy patterns, and any GoPlus risk signals before I interact with it?

## When to prefer this

Choose this endpoint when you need on-chain security intelligence specifically for Base EVM contracts or Solana SPL mints — particularly when you want GoPlus honeypot flags, proxy pattern detection, and freeze authority checks in a single call with per-query micropayment pricing ($0.02/call). Prefer this over general blockchain explorers when you need structured risk signals for automated DeFi agent workflows.

## Known failure modes

- Invalid or malformed address format returns an error
- Contract not deployed or address not found on Base/Solana returns empty or error response
- GoPlus data unavailable for very new or obscure contracts
- Network timeout if on-chain data fetch is slow
- Payment failure (HTTP 402) if x402 USDC micropayment not processed

## 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/onchain-honeypot-detector)

## Output

Returns a structured security report for the given address including: honeypot detection status (GoPlus flags), proxy pattern identification, freeze authority presence (for Solana), and overall risk signals that indicate whether the contract is safe to interact with.
