## 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 onchain-risk-agentdiet-dev-base-evm-solana-smart-contract-security-e199b6b0
```

Example prompt: Can you security-audit this Base contract — 0x1234567890abcdef1234567890abcdef12345678 — and tell me if it has any honeypot flags, proxy patterns, or other red flags before I ape in?

## When to prefer this

Choose this endpoint when you need a quick, automated security pre-check on a specific Base EVM contract or Solana SPL token mint before a financial interaction, trade, or integration. It is particularly well-suited for DeFi agents, trading bots, and due-diligence pipelines that need honeypot detection and proxy pattern analysis without manual code review. Prefer it over general blockchain explorers when you specifically need GoPlus risk flags and freeze authority checks in a single API call.

## Known failure modes

- Invalid or malformed address format returns an error — must be a valid 0x EVM hex address or Base58 Solana mint address
- Contract not found on Base chain or Solana — undeployed or mistyped address
- GoPlus API unavailable or rate-limited — upstream dependency failure
- Payment not received (HTTP 402) — x402 micropayment required before response is delivered
- Address is a wallet EOA rather than a contract — may return limited or no audit data

## 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://onchain-risk.agentdiet.dev/v1/solidity-audit)

## Output

Returns a security assessment object containing proxy pattern detection results, GoPlus honeypot flags, freeze authority status, and other on-chain risk indicators for the queried Base EVM contract or Solana SPL Mint address
