## 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-7cbca88d
```

Example prompt: Can you scan the Base contract 0x4ed4e862860bed51a9570b96d89af5e1b0efefed for honeypot flags and proxy patterns before I buy in?

## When to prefer this

Choose this endpoint when you need rapid pre-trade security screening of a Base EVM token contract or Solana SPL mint, especially when honeypot detection, proxy upgradeability risk, and freeze authority are the primary concerns. It is ideal for DeFi trading agents, portfolio risk monitors, or wallet tools that need a fast $0.01-per-call check before executing a swap or approving a contract interaction.

## Known failure modes

- Invalid or malformed address returns an error — ensure 0x prefix for EVM or valid Base58 for Solana
- Contract not indexed by GoPlus may return limited or no honeypot data
- Very new or unverified contracts may lack sufficient on-chain data for a full audit
- Payment failure via x402 will block the response with HTTP 402
- Rate limiting or network issues may cause timeouts for live on-chain lookups

## 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/onchain-honeypot-detector)

## Output

Returns a structured security report including GoPlus honeypot detection flags, proxy pattern indicators (upgradeable/transparent proxy), freeze authority status for Solana SPL mints, and overall risk signals for the queried contract or mint address.
