## 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-0c9bfa0d
```

Example prompt: Before I buy this token, can you scan the contract 0x1234abcd...efgh on Base for honeypot flags, proxy upgrade patterns, or any other red flags that could mean it's a rug pull?

## When to prefer this

Choose this endpoint when you need a fast, per-address smart contract security check on Base EVM or Solana before interacting with or investing in a token — especially to catch honeypots, freeze authority risks, and proxy upgrade patterns. Prefer this over manual block explorer review when you need programmatic, structured risk data at $0.01 per call in an automated agent or trading workflow.

## Known failure modes

- Invalid or malformed address format returns an error
- Unrecognized chain or address type not supported
- Contract not yet deployed or address does not exist on-chain
- GoPlus data unavailable for newly deployed contracts
- Payment required (HTTP 402) if x402 USDC micropayment not completed
- Rate limiting if too many requests in a short window

## 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/risk)

## Output

A structured JSON object containing security findings for the queried address, including whether proxy/upgradeable patterns are detected, GoPlus honeypot flags and their details, freeze authority status (for Solana SPL mints), and an overall risk assessment indicating whether the contract poses known security risks.
