## 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-a84b60cc
```

Example prompt: Can you run a full security audit on the Base EVM contract 0x4200000000000000000000000000000000000006 — check for honeypot flags, proxy patterns, and any other risks?

## When to prefer this

Choose this endpoint when you need a quick, on-demand security scan of a specific Base EVM or Solana SPL token contract before trading, investing, or integrating — especially when you want combined honeypot, proxy pattern, and freeze authority checks in a single call. Prefer it over manual block explorer lookups or full audit firms when you need automated, per-contract risk signals at low cost ($0.02/call) without setting up your own GoPlus integration.

## Known failure modes

- Invalid or malformed address returns an error (non-0x EVM or invalid Base58 Solana address)
- Address not found on Base or Solana mainnet returns empty or no-data result
- GoPlus API unavailability may cause upstream lookup failure
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not completed
- Contract at address is unverified and cannot be fully analyzed

## 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/smart-contract-audit)

## Output

Returns a structured JSON object containing security findings for the given contract or mint address, including: detected proxy patterns, GoPlus honeypot flags (e.g. buy/sell tax traps, blacklist functions), freeze authority status for Solana SPL tokens, and an overall risk assessment.
