## 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-d96a60db
```

Example prompt: Can you run a security scan on the Base contract at 0x4200000000000000000000000000000000000006 and tell me if it has any proxy upgrade patterns or honeypot flags?

## When to prefer this

Choose this endpoint when you need a combined on-chain security check covering both Base EVM contracts and Solana SPL mints in a single call, specifically for proxy upgrade risk, GoPlus honeypot detection, and freeze authority — especially in DeFi due-diligence workflows where token safety must be verified before trading, listing, or investing.

## Known failure modes

- Invalid or malformed address format returns an error (neither valid 0x EVM nor Base58 Solana address)
- Contract address not found on Base network or Solana mainnet returns empty or null results
- GoPlus API unavailability may degrade honeypot flag accuracy
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not processed
- Non-contract wallet address (EOA) may return limited results with no proxy/honeypot 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://x402-audit.agentdiet.dev/v1/proxy-upgrade-risk)

## Output

Returns a structured security report indicating whether the contract exhibits proxy or upgradeable patterns, GoPlus honeypot risk flags, freeze authority presence (for Solana SPL tokens), and an overall upgrade/rug risk assessment for the provided address.
