## 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 json-repair-agentdiet-dev-base-evm-solana-smart-contract-security-9e5994d0
```

Example prompt: Can you scan the Base contract 0x1234abcd...5678 for honeypot flags, proxy upgrade patterns, and any freeze authority risks before I interact with it?

## When to prefer this

Choose this endpoint when you need a fast, on-chain security pre-check on a Base EVM contract or Solana SPL Mint before interacting with it in a DeFi context — particularly when you want combined proxy-upgrade risk, honeypot detection via GoPlus, and freeze authority status in a single call. It is especially useful for agents automating token purchases, LP decisions, or investment due diligence where rug-pull or honeypot risk must be assessed programmatically without manual auditing.

## Known failure modes

- Invalid or malformed address returns an error indicating the address format is unrecognized
- Undeployed or non-existent contract address may return empty or null security data
- Solana address passed to EVM path or vice versa may produce incorrect results
- GoPlus API downtime may cause incomplete honeypot data
- Payment not included or insufficient (HTTP 402) blocks the response
- Rate limiting may occur under high request volume

## 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://json-repair.agentdiet.dev/v1/proxy-upgrade-risk)

## Output

Returns a structured JSON object with findings on proxy/upgrade patterns (e.g. transparent or UUPS proxy detection), GoPlus honeypot flags (buy/sell tax anomalies, blacklist functions), and freeze authority status for Solana SPL mints, along with an overall risk assessment for the provided contract or mint address.
