## 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 x402-audit-agentdiet-dev-base-evm-solana-smart-contract-security-81bc9c38
```

Example prompt: Can you run a security audit on this Base contract — 0x1234abcd... — and tell me if it's flagged as a honeypot, uses a proxy pattern, or has any freeze authority issues?

## When to prefer this

Choose this endpoint when you need a fast, automated pre-trade or pre-interaction security check on a Base EVM contract or Solana SPL mint — specifically when you want GoPlus honeypot flags, proxy upgrade pattern detection, and freeze authority checks in a single call. Prefer this over general block explorer lookups when you need machine-readable risk signals for autonomous agent decision-making around DeFi token safety.

## Known failure modes

- Invalid or malformed address (non-0x EVM and non-Base58 Solana) returns a validation error
- Address not found on-chain or unsupported network returns empty or null results
- GoPlus API upstream timeout results in partial or delayed response
- Rate limiting or payment failure (HTTP 402) if x402 USDC payment is not included
- Contract is too new or unindexed, resulting in incomplete security data

## 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://x402-audit.agentdiet.dev/v1/mint-authority-check)

## Output

Returns a structured security report for the given contract or mint address, including proxy pattern detection results, GoPlus honeypot flags (true/false with reason codes), freeze authority status for Solana SPL mints, and an overall risk assessment. The response is a JSON object summarizing each security dimension checked.
