## 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 preflight-agentdiet-dev-base-evm-solana-smart-contract-security-scanner-0cf9d9eb
```

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

## When to prefer this

Choose this endpoint when you need a fast, automated pre-trade or pre-integration security check on a Base EVM contract or Solana SPL Mint address. It is especially useful when you need honeypot detection, proxy/upgradeable pattern detection, and freeze authority checks combined in a single call, rather than querying GoPlus or on-chain data manually. Prefer it for DeFi agent workflows, trading bots, or risk dashboards that need to vet unknown contracts programmatically before committing funds.

## Known failure modes

- Invalid or malformed address returns an error response
- Contract not found on Base or Solana returns empty/null results
- GoPlus data unavailable for very new or obscure contracts
- Rate limiting or payment failure (402) if x402 USDC micropayment is not provided
- Network-level timeout if the blockchain RPC is slow

## 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://preflight.agentdiet.dev/v1/contract-scanner)

## Output

Returns a security report for the given contract or mint address, including whether proxy/upgradeable patterns are detected, GoPlus honeypot flag status, freeze authority presence (for Solana SPL tokens), and an overall risk assessment.
