## 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 x402broker-com-base-evm-solana-smart-contract-security-scanner-d9263d95
```

Example prompt: Can you run a rug check on this Base contract — 0x1234567890abcdef1234567890abcdef12345678 — and tell me if it has any honeypot flags or proxy patterns I should worry about?

## When to prefer this

Choose this endpoint when you need fast, automated pre-trade or pre-interaction security screening of Base EVM contracts or Solana SPL Mints, specifically for honeypot detection, proxy upgrade pattern risks, and freeze authority flags. It is ideal for DeFi trading bots, portfolio risk monitors, and agent-driven token discovery workflows where a $0.01-per-call cost is acceptable. Prefer this over generic block explorers when you need structured, machine-readable risk signals rather than raw on-chain data.

## Known failure modes

- Invalid or malformed address format returns an error (non-0x EVM or invalid Base58 Solana address)
- Contract address not deployed on Base returns empty or not-found result
- GoPlus API unavailable or rate-limited causes degraded or missing honeypot flags
- Newly deployed contract with no transaction history may yield incomplete risk signals
- Solana address passed to EVM scanner or vice versa may cause routing errors

## 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://x402broker.com/v1/rug-check)

## Output

Returns a JSON object containing security risk signals for the given contract or mint address, including whether the contract is flagged as a honeypot by GoPlus, whether proxy upgrade patterns are detected (which could allow owner-controlled rug pulls), and whether freeze authority is present on a Solana SPL mint. The response synthesizes on-chain and GoPlus intelligence into actionable risk indicators.
