## 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 x402broker-com-base-evm-solana-smart-contract-security-scanner-137ffd3b
```

Example prompt: Can you scan the Base EVM contract 0xAbC123... 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 automated, pre-trade or pre-interaction security screening of a Base EVM contract or Solana SPL Mint — especially when you want GoPlus honeypot intelligence and proxy/freeze authority checks in a single call. It is better than generic block explorers for structured, agent-consumable risk signals and is the right choice for DeFi safety workflows, token launch vetting, or wallet KYT (Know Your Transaction) pipelines on Base and Solana.

## Known failure modes

- Invalid or malformed address format returns an error
- Address not found on Base or Solana network may return empty results
- GoPlus API upstream downtime may cause delayed or failed responses
- Newly deployed contracts may have limited data available
- Rate limiting or payment failure returns HTTP 402

## Output

Returns a structured security report for the given contract or mint address, including whether proxy patterns are detected, GoPlus honeypot classification flags, freeze authority status on Solana, and any other on-chain risk signals that could indicate malicious or risky smart contract behavior.
