Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-495adcfb
```

Example prompt: Can you scan the Base 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 fast, per-call on-chain security check for Base EVM contracts or Solana SPL Mints, especially when you want honeypot detection via GoPlus and proxy pattern analysis in a single call. Prefer it over manual block explorer review or general-purpose audit tools when you need programmatic, agent-friendly risk signals at low cost ($0.01/call) before executing a DeFi trade, providing liquidity, or interacting with an unknown contract.

## Known failure modes

- Invalid or malformed address returns an error response
- Unsupported chain or address format (not Base EVM 0x or Solana Base58) may yield empty or error results
- GoPlus data unavailable for newly deployed contracts with no on-chain history
- Payment failure (HTTP 402) if x402 USDC microtransaction is not completed
- Rate limiting if too many requests are made in quick succession
- Network timeout if the target chain RPC is congested

## 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/wallet-kyt)

## Output

Returns a JSON object containing security findings for the queried address, including proxy pattern detection results, GoPlus honeypot flags, freeze authority status (for Solana SPL mints), and an overall risk assessment indicating whether the contract or token poses known security threats.
