## 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-e7582fc6
```

Example prompt: Can you check if this Base contract 0x4fabb145d64652a948d72533023f6e7a623c7c53 is a honeypot or has any shady proxy patterns I should worry about before I swap into it?

## When to prefer this

Choose this endpoint when you need on-chain security validation of a specific Base EVM contract or Solana SPL mint before trading, investing, or integrating a token. It is especially valuable for DeFi agents performing pre-trade safety checks, portfolio risk screening, or token listing due diligence. Prefer this over generic blockchain explorers when you specifically need honeypot detection, proxy upgrade pattern analysis, or Solana freeze authority flags in a single call.

## Known failure modes

- Invalid or malformed address returns an error indicating address format mismatch
- Unknown or undeployed contract address may return empty or inconclusive results
- Solana address passed to EVM scanner path (or vice versa) may return no match
- Network timeouts from GoPlus upstream API result in degraded or null responses
- Rate limiting or payment failure (x402) causes 402 response requiring USDC payment

## 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/honeypot-check)

## Output

Returns a structured security report for the queried contract or mint address, including honeypot detection flags from GoPlus, proxy pattern analysis, freeze authority status (for Solana), and an overall risk assessment indicating whether the contract poses known threats to traders or holders.
