## 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-ab5920a3
```

Example prompt: Can you scan the contract 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base for honeypot flags, proxy patterns, and any other red flags before I ape in?

## When to prefer this

Choose this endpoint when you need a fast, automated security pre-check on a specific Base EVM contract or Solana SPL Mint before trading, investing, or integrating it — especially when you need honeypot detection (via GoPlus), proxy upgrade pattern analysis, and freeze authority checks in a single call. Prefer this over manual block explorer review or generic audit tools when you need structured, machine-readable risk signals at $0.02 per call.

## Known failure modes

- Invalid or malformed address returns an error — must be a valid 0x EVM address or Base58 Solana mint
- Address not found on supported networks returns empty or null results
- GoPlus data unavailable for very new or obscure contracts may yield incomplete flags
- Network timeouts may occur if on-chain lookups take too long
- Payment required (HTTP 402) if x402 micropayment is not included in the request

## 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/onchain-honeypot-detector)

## Output

Returns a structured security assessment including honeypot detection status (from GoPlus), proxy pattern identification, freeze authority flags for Solana mints, and overall risk indicators for the queried contract or token address.
