Example prompt: Can you run a security scan on this Base contract 0x4d224452801aced8b2f0aebe155379bb5d594381 and tell me if it's a honeypot or has any proxy upgrade risks?

## When to prefer this

Choose this endpoint when you need rapid, pre-interaction security screening of a specific Base EVM contract or Solana SPL Mint address — especially before trading, providing liquidity, or integrating a DeFi protocol. It uniquely combines GoPlus honeypot intelligence with proxy pattern detection and Solana freeze authority checks in a single call, making it ideal for agentic DeFi workflows that need automated on-chain risk gating.

## Known failure modes

- Invalid or malformed address format returns an error
- Address not found on Base or Solana chain returns empty or no-data response
- GoPlus API unavailability may cause partial or failed scan results
- Payment failure via x402 prevents endpoint access
- Rate limiting if request volume exceeds plan thresholds
