## 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-1342ccd2
```

Example prompt: Can you scan the Base contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 for honeypot flags, proxy patterns, and any other security red flags before I interact with it?

## When to prefer this

Choose this endpoint when you need a quick, automated pre-interaction security check on a specific Base EVM or Solana token/contract address — especially to detect honeypots, proxy upgrade risks, and mint freeze authority before executing a trade, integration, or investment. Prefer this over general blockchain explorers when you need structured, agent-parseable risk signals rather than raw on-chain data.

## Known failure modes

- Invalid or malformed address format returns an error
- Address not found on Base or Solana chain returns empty/null result
- GoPlus API upstream unavailability may cause degraded or missing honeypot data
- Network timeouts for newly deployed contracts with limited on-chain history
- Payment not fulfilled (HTTP 402) if x402 payment is not attached

## 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/mint-authority-check)

## Output

Returns a structured JSON object indicating whether the contract exhibits proxy upgrade patterns, GoPlus honeypot detection results, freeze authority status (for Solana SPL mints), and overall risk signals for the queried address on Base EVM or Solana.
