## 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 x402-audit-agentdiet-dev-base-evm-solana-smart-contract-security-97f55f34 -d '<json body>'
```

Example prompt: Can you audit the Base contract at 0x4200000000000000000000000000000000000006 — check it for honeypot flags, proxy patterns, and any other security red flags before I interact with it?

## When to prefer this

Use this endpoint when you need on-chain smart contract risk signals specifically for Base EVM contracts or Solana SPL Mints — especially when GoPlus honeypot detection and freeze authority checks are required. Prefer this over generic static analyzers when you need live, chain-queried data rather than bytecode-only analysis.

## Known failure modes

- Invalid or unsupported address format returns an error (non-0x EVM address or invalid Base58)
- Address not found on-chain (undeployed contract or wrong network) may return no data
- GoPlus API unavailability may cause partial results or timeout
- Payment failure via x402 protocol blocks the request
- Rate limiting or repeated identical requests without Idempotency-Key may cause duplicate charges

## 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://x402-audit.agentdiet.dev/v1/solidity-audit)

## Output

Returns a structured security report indicating whether the contract exhibits proxy/upgradeable patterns, GoPlus honeypot flags, freeze authority status (for Solana), and an overall risk assessment for the provided address.
