Example prompt: Can you run a security audit on the Base EVM contract 0x4200000000000000000000000000000000000006 and tell me if it has any honeypot flags, proxy patterns, or other red flags?

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01) security scan of a specific Base EVM contract or Solana SPL Mint before trading, investing, or integrating. It uniquely combines GoPlus honeypot detection, proxy pattern analysis, and Solana freeze authority checks in a single call — ideal for DeFi agents performing pre-trade risk checks or portfolio screening tools vetting new token listings.

## Known failure modes

- Invalid or malformed address returns an error indicating unrecognized format
- Contract not yet indexed by GoPlus may return incomplete or null honeypot data
- Solana non-SPL mint addresses may fail validation
- Network timeouts from upstream GoPlus or on-chain RPC can cause delayed or empty responses
- Undeployed or self-destructed contracts may return no 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://onchain-risk.agentdiet.dev/v1/smart-contract-audit)

## Output

Returns a structured security report for the given contract or mint address, including detected proxy patterns (e.g. upgradeable proxies), GoPlus honeypot flag results, freeze authority status (for Solana SPL tokens), and overall risk indicators that help determine whether the contract poses a threat to investors or integrators.
