How this service works
Honeypot.is buy/sell simulation for any Base or Ethereum ERC-20. Returns is_honeypot verdict, buy/sell/transfer tax %, simulation success flag, and a reason string when a honeypot is detected. Use before every swap to detect sell-blocking risk.
Output
Returns a JSON object containing: is_honeypot (boolean verdict), buy_tax (%), sell_tax (%), transfer_tax (%), simulation_success (boolean flag indicating whether the simulated transaction completed), and a reason string explaining why a honeypot was detected when applicable.
Example use cases
Pre-swap honeypot guard for DeFi bot
“I'm about to buy token 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum — run a honeypot simulation first and tell me the buy tax, sell tax, and whether selling is actually possible.”
Rug pull screening for new Base token
“There's a new token on Base at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — check if it's a honeypot and what the transfer tax percentage is before I put any money in.”
Automated safety check in trading pipeline
“As part of my token screening workflow, run a honeypot check on ERC-20 contract 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum and return the full verdict including sell tax and the reason string if it's flagged.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/honeypot-checkWhen to prefer
Choose this endpoint when you need a fast, automated pre-swap safety check for any ERC-20 on Ethereum or Base, especially when running an autonomous trading agent that needs to screen tokens before executing swaps. It is particularly valuable over manual inspection because it simulates actual buy/sell transactions and returns structured tax data and a definitive honeypot verdict. Prefer this over general contract auditing tools when you need real-time simulation results rather than static code analysis.
Side effects
- Invalid or non-existent contract address — simulation fails with an error or empty result
- Unsupported network specified — returns error if chain is not Base or Ethereum
- Contract has no liquidity — simulation may return inconclusive or failed result
- Token is a proxy or upgradeable contract — simulation results may not reflect actual behavior
- Rate limit or payment failure — x402 payment not processed, request rejected
- Newly deployed contract with no on-chain activity — simulation success flag may be unreliable
