Token Safety Checker (Honeypot & Transfer Tax Simulation)
x402
Token Safety Checker (Honeypot & Transfer Tax Simulation) is a paid API for AI agents from yonder-spotless-stranger.ngrok-free.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).
Simulates a real token holder selling an ERC-20 token to detect honeypots and measure the exact transfer tax in basis points before you buy.

How this service works
Honeypot and transfer-tax check done by simulation, not heuristics: we find a real holder of the token and simulate them selling it, then report whether the sell succeeds and the transfer tax in basis points. Answers the only question that matters before you buy — can you get back out?
Output
Returns whether a simulated sell transaction succeeds or fails (honeypot detection) and the transfer tax charged in basis points, derived from an actual on-chain simulation using a real token holder — not heuristics.
Example use cases
Pre-buy honeypot check on new token
“I'm about to ape into this Base token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — can you simulate a holder selling it and tell me if it's a honeypot and what the transfer tax is?”
Memecoin tax verification before trading
“What's the actual transfer tax on this Ethereum mainnet token 0x95aD61b0a150d79219dCF64E1E6Cc01f0B64C4cE? Simulate a real sell and give me the tax in basis points.”
DeFi bot pre-trade safety gate
“Check whether token 0xdAC17F958D2ee523a2206206994597C13D831ec7 on mainnet is safe to sell — run the simulation and confirm there are no sell restrictions or surprise taxes before I execute the trade.”
Technical details
Endpoint
POSThttps://yonder-spotless-stranger.ngrok-free.dev/token-safetyWhen to prefer
Choose this endpoint when you need a definitive, simulation-based answer on whether a token is a honeypot or carries a transfer tax — not a heuristic or static code scan. It is especially valuable immediately before executing a buy, in a trading bot's pre-trade safety gate, or when evaluating obscure/new tokens where static analysis tools give false confidence. Prefer it over bytecode scanners when you need ground-truth sellability confirmation on Ethereum mainnet or Base.
Side effects
- Token address not found or invalid on specified chain
- No real holder found to simulate the sell from
- Simulation reverts due to insufficient liquidity or edge-case contract state
- Unsupported chain specified (only 'mainnet' and 'base' are valid)
- Network RPC timeout causing simulation failure
- Payment not accepted or insufficient USDC balance
