## 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-d03b36c8
```

Example prompt: Can you scan the Base contract 0x4200000000000000000000000000000000000006 for honeypot flags, proxy upgrade patterns, and any GoPlus security red flags before I ape in?

## When to prefer this

Choose this endpoint when you need a fast, automated pre-trade or pre-interaction security check on a Base EVM contract or Solana SPL Mint — particularly when you need GoPlus honeypot analysis combined with proxy pattern and freeze authority detection in a single call. Prefer it over generic block explorers when you need machine-readable risk signals for agent-driven DeFi workflows.

## Known failure modes

- Invalid or malformed address format — returns error if the address is neither a valid 0x EVM address nor a Base58 Solana address
- Contract not found on Base or Solana — may return empty or null risk data
- GoPlus API upstream unavailability — scanner may return degraded or timeout error
- Payment failure via x402 — returns HTTP 402 if USDC payment is not completed
- Rate limiting — too many requests in a short window may result in throttling

## 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/tax-honeypot-scan)

## Output

Returns a structured security report for the given address, including GoPlus honeypot flags (can_not_sell, high_tax, etc.), proxy pattern detection (whether the contract uses an upgradeable proxy), and freeze authority status for Solana SPL mints, indicating overall risk level for trading or interacting with the contract.
