## 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-d5ce679b
```

Example prompt: Can you scan the Base EVM 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 a quick, pay-per-call security scan of a specific Base EVM contract or Solana SPL Mint without setting up a full security auditing pipeline. It is ideal for DeFi agents that need to assess contract risk before executing a swap, investment, or integration. Prefer this over manual block explorer review when you need structured, programmatic risk signals (honeypot, proxy, freeze authority) returned in a single call.

## 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 returns empty or not-found result
- GoPlus data unavailable for a newly deployed contract
- Payment (x402) not satisfied returns HTTP 402
- Rate limiting or upstream GoPlus API timeout returns 5xx error

## 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/risk)

## Output

Returns a risk assessment object indicating whether the queried address exhibits proxy contract patterns, honeypot behavior as flagged by GoPlus, freeze authority (for Solana SPL mints), and other security risk signals relevant to the contract or token.
