## 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 prompt-guard-agentdiet-dev-base-evm-solana-smart-contract-security-afbb1735
```

Example prompt: Can you scan the Base contract 0x1234abcd...5678 for honeypot traps, proxy patterns, and other security red flags before I interact with it?

## When to prefer this

Use this endpoint when you need a fast, automated pre-transaction security scan of a specific Base EVM contract or Solana SPL Mint — particularly when checking for honeypot traps, proxy upgrade patterns, or freeze authority before a DeFi swap, LP deposit, or token purchase. Prefer this over manual block explorer review when operating in an agentic workflow that requires programmatic risk signals.

## Known failure modes

- Invalid or malformed address returns an error — ensure 0x addresses are valid EVM hex and Solana addresses are valid Base58
- Address not found on Base or Solana results in empty or null scan data
- GoPlus API unavailability may cause degraded honeypot detection results
- Rate limiting or payment failure (402) if x402 USDC micropayment is not completed
- Non-contract wallet addresses may return limited or 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://prompt-guard.agentdiet.dev/v1/contract-scanner)

## Output

Returns a structured security report for the given contract or SPL mint address, including whether the contract uses proxy upgrade patterns, whether GoPlus has flagged it as a honeypot, and whether freeze authority is enabled — allowing agents or users to assess on-chain risk before transacting.
