## 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-096fbcb3
```

Example prompt: Can you scan the Base contract 0x1234567890abcdef1234567890abcdef12345678 for honeypot flags, proxy upgrade patterns, and any GoPlus security risks before I ape in?

## When to prefer this

Choose this endpoint when you need automated, agent-friendly on-chain security screening for Base EVM contracts or Solana SPL mints before executing a trade, providing liquidity, or interacting with an unknown protocol. It combines GoPlus honeypot detection with proxy pattern analysis and Solana freeze authority checks in a single call, making it superior to manual block explorer review or separate GoPlus API integration.

## Known failure modes

- Invalid or malformed address returns a 400 error
- Address not found on Base or Solana returns empty or null risk data
- GoPlus API upstream timeout results in incomplete scan
- Newly deployed contracts with no on-chain history may return limited data
- Payment not fulfilled (HTTP 402) if x402 micropayment is not completed

## 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/flashloan-vuln-check)

## Output

Returns a structured security report indicating whether the contract or SPL mint has proxy upgrade patterns, GoPlus honeypot flags (e.g. cannot sell, hidden fees, blacklist functions), and freeze authority status, along with overall risk signals to help an agent or user decide whether to interact with the contract.
