## 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 defi-yield-agentdiet-dev-base-evm-solana-smart-contract-security-744da6a8
```

Example prompt: Can you run a security scan on this Base contract — 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — and tell me if it's flagged as a honeypot, uses a proxy pattern, or has any GoPlus risk warnings?

## When to prefer this

Choose this endpoint when you need a fast, automated security pre-check on a Base EVM contract or Solana SPL token mint before interacting with it, investing, or integrating it into a DeFi workflow. It is especially valuable for detecting honeypots and freeze authority risks that are common in rug pulls and scam tokens. Prefer this over generic blockchain explorers when you need structured, GoPlus-powered risk flags rather than raw on-chain data.

## Known failure modes

- Invalid or malformed address format returns an error (neither valid 0x EVM nor Base58 Solana address)
- Contract address not found on Base or Solana mainnet returns empty or not-deployed result
- GoPlus API rate limits or downtime may cause delayed or failed responses
- Very new or unindexed contracts may have incomplete security data
- Payment failure (HTTP 402) if USDC balance is insufficient

## 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://defi-yield.agentdiet.dev/v1/contract-scanner)

## Output

Returns a structured security report for the given contract or mint address, including proxy pattern detection results, GoPlus honeypot flags (buy/sell tax anomalies, blacklist functions, ownership renouncement status), freeze authority presence for Solana SPL tokens, and an overall risk assessment.
