## 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 onchain-risk-agentdiet-dev-base-evm-solana-smart-contract-security-e17ca222
```

Example prompt: Can you run a security audit on this Base contract — 0x1234abcd5678ef901234abcd5678ef901234abcd — and tell me if it has any honeypot flags, proxy patterns, or other red flags before I interact with it?

## When to prefer this

Choose this endpoint when you need a combined EVM + Solana smart contract security check that covers honeypot detection (via GoPlus), proxy pattern analysis, and freeze authority in a single API call. Prefer it over manual block explorer lookups when automating pre-trade or pre-integration risk checks in DeFi agent workflows on Base or Solana networks.

## Known failure modes

- Invalid or malformed address returns an error (non-0x EVM or invalid Base58 Solana format)
- Address not found on Base or Solana network returns empty or null results
- GoPlus API rate limiting or downstream outage may cause partial or failed responses
- Newly deployed contracts with no on-chain history may return limited data
- Payment failure (402) if $0.01 USDC micropayment via x402 is not resolved

## 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://onchain-risk.agentdiet.dev/v1/contract-scanner)

## Output

Returns a structured security report for the queried address including: proxy pattern detection, GoPlus honeypot flags (buy/sell tax anomalies, blacklist functions, ownership risks), and freeze authority status for Solana SPL mints — enabling agents to assess on-chain risk before transacting
