Check a token on BNB Smart Chain, Ethereum, Base or Arc for traps before buying it. ChainK9 forks the chain and really buys and sells the token in a sandbox (its V2 or V3 pool: PancakeSwap on BSC, Uniswap on Ethereum and Base; or its Uniswap V4 pool, hook included; on Arc, V4 pools against native USDC only for now), then runs 60+ checks: honeypot, hidden and changing buy and sell taxes, owner pause, blacklist, mint and confiscation powers, transfer and sell limits, cooldowns, liquidity, upgrade authority. Returns a verdict (danger, caution, ok) and every check's result. Results are reused for 10 minutes. Not charged when the address isn't a token or has no liquidity yet (422). Costs $0.02 per successful call in USDC on Base, paid with x402 in the call's _meta; failed calls are free.
