## 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 serp-extract-agentdiet-dev-base-evm-solana-smart-contract-security-b27f92e7 -d '<json body>'
```

Example prompt: Can you scan this Base contract 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 for honeypot flags, proxy patterns, and any freeze authority risks before I buy in?

## When to prefer this

Choose this endpoint when you need a fast, combined security scan of a Base EVM contract or Solana SPL Mint that covers honeypot detection (via GoPlus), proxy/upgrade pattern flags, and freeze authority checks in a single call. Prefer this over generic block explorer lookups when you need agent-ready structured risk signals rather than raw on-chain data, and when you need to evaluate DeFi token safety before executing a trade or providing liquidity.

## Known failure modes

- Invalid or malformed address returns a validation error
- Address not found on Base or Solana returns empty or null risk data
- GoPlus API unavailability may cause upstream timeout errors
- Non-contract wallet addresses may return limited or no honeypot data
- Newly deployed contracts with no on-chain history may lack sufficient data for full analysis

## 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://serp-extract.agentdiet.dev/v1/onchain-risk)

## Output

Returns a structured security report for the queried address including proxy pattern detection (e.g. upgradeable proxy indicators), GoPlus honeypot flag status, freeze authority presence (for Solana mints), and overall risk signals that help an agent determine whether the contract or token is safe to interact with.
