## 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 json-repair-agentdiet-dev-base-evm-solana-smart-contract-security-15351218
```

Example prompt: Can you scan the Base EVM contract at 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 on-chain security signals specifically for Base EVM contracts or Solana SPL mints, particularly when you want GoPlus honeypot analysis, proxy upgrade pattern detection, and freeze authority checks in a single call. Prefer this over generic contract explorers when you need machine-readable risk flags for agent decision-making rather than human-readable block explorer output.

## Known failure modes

- Invalid or malformed address format returns an error — ensure 0x prefix for EVM or valid Base58 for Solana
- Contract not deployed or unverified on-chain may return limited results
- GoPlus API downtime or rate limiting may cause partial data
- Newly deployed contracts with no transaction history may lack honeypot signal
- Payment failure (HTTP 402) if x402 USDC payment is not correctly submitted

## 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://json-repair.agentdiet.dev/v1/flashloan-vuln-check)

## Output

Returns a structured security report covering: proxy pattern detection (whether the contract is upgradeable or uses delegatecall patterns), GoPlus honeypot flags (buy/sell tax anomalies, blacklist functions, trading restrictions), and freeze authority status (for Solana SPL mints). May include overall risk rating and specific vulnerability indicators relevant to the scanned address.
