## 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-c706a12e
```

Example prompt: Can you scan this Base contract address 0x1234abcd... for honeypot flags, proxy patterns, and any freeze authority risks before I interact with it?

## When to prefer this

Choose this endpoint when you need on-chain smart contract security checks specifically for Base EVM contracts or Solana SPL Mints, particularly when GoPlus honeypot detection and freeze authority analysis are required. Prefer this over general blockchain explorers when you want automated risk flags rather than raw on-chain data, and when operating in an agent context that supports HTTP 402 micropayments.

## Known failure modes

- Invalid or malformed address format returns an error
- Address not found on Base or Solana networks returns empty or null results
- GoPlus API downstream outage may cause incomplete honeypot data
- Very new or unverified contracts may have limited bytecode analysis available
- Payment failure (HTTP 402) if USDC micropayment is not processed correctly

## 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/bytecode-scanner)

## Output

Returns a JSON object containing security findings for the given address, including detected proxy pattern types, GoPlus honeypot flag status and reasons, freeze authority presence (for Solana mints), and an overall risk assessment summary.
