## 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 preflight-agentdiet-dev-base-evm-solana-smart-contract-security-scanner-6cec43e0
```

Example prompt: Can you scan the contract 0x4d224452801ACEd8B2F0aebE155379bb5D594381 on Base for honeypot flags, proxy patterns, and any freeze authority issues before I interact with it?

## When to prefer this

Choose this endpoint when you need rapid, automated on-chain security screening of a specific Base EVM contract or Solana SPL Mint before a financial interaction, investment, or integration. It is especially well-suited for DeFi agents that need GoPlus honeypot signals combined with proxy-pattern and freeze-authority detection in a single call, without requiring a full manual audit. Prefer this over generic blockchain explorers when you need structured, machine-readable risk flags rather than raw chain data.

## Known failure modes

- Invalid or malformed address returns an error (non-0x EVM or non-Base58 Solana address)
- Address not found on Base or Solana chain returns empty or null risk data
- GoPlus API unavailability may result in partial results or degraded honeypot signals
- Payment failure (x402) prevents access to results
- Non-contract wallet addresses may return limited audit data

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

## Output

Returns a structured security report including proxy pattern detection, GoPlus honeypot flag results, and freeze authority status for the given Base EVM contract or Solana SPL Mint address, enabling agents to assess on-chain risk before interacting with or recommending a token or protocol.
