## 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-2811e736
```

Example prompt: Can you scan the Base contract 0x4200000000000000000000000000000000000006 for honeypot flags, proxy patterns, and any other security risks before I interact with it?

## When to prefer this

Choose this endpoint when you need on-chain security intelligence specifically for Base EVM contracts or Solana SPL Mint addresses, combining proxy pattern detection, GoPlus honeypot flags, and freeze authority checks in a single call. Prefer this over generic blockchain explorers when you need structured, agent-readable risk signals rather than raw explorer data. Ideal for DeFi due diligence workflows, pre-trade safety checks, or automated token screening pipelines where x402 micropayment integration is acceptable.

## Known failure modes

- Invalid or malformed address format returns an error
- Address not found on Base or Solana network
- GoPlus API unavailable or rate-limited causing incomplete honeypot data
- Payment (x402) not fulfilled results in HTTP 402 response
- Network timeout for slow on-chain lookups
- Unverified or newly deployed contract with insufficient on-chain 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/api)

## Output

Returns a structured risk report for the submitted contract or mint address, including: detection of proxy/upgradeable patterns, GoPlus honeypot classification flags, freeze authority status (for Solana SPL mints), and overall risk indicators — enabling agents to assess whether the contract is safe to interact with or trade against.
