How this service works
Token risk checks for BNB Smart Chain, Ethereum and Base, for AI agents and trading bots. ChainK9 forks the chain and really buys and sells a token in a sandbox before you do, so a honeypot is caught by what it does, not by what its code looks like.
Output
Returns a JSON object with a top-level verdict (e.g. 'pass', 'caution', 'fail'), the token and pair addresses, the chain, block number, scan timestamp, pool version, whether the result was cached, and a results array of individual check modules each with a module name, category, status (pass/warn/fail), severity (critical/high/medium/low), and a human-readable detail string describing the finding.
Example use cases
Pre-trade honeypot check for trading bot
“My trading bot is about to buy 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095e on BNB Smart Chain — before it executes, do a live sandbox simulation to check if it's a honeypot or if I can't sell it afterwards.”
Ethereum DeFi token safety scan
“I'm looking at this Ethereum token at 0xdAC17F958D2ee523a2206206994597C13D831ec7 — can you do a real buy-and-sell simulation to check for hidden fees, sell restrictions, or owner mint powers before I put money in?”
Base chain token rug pull verification
“Check this Base chain token address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 for rug pull risks — I want to know the verdict, any sell tax, and whether the owner can mint more tokens.”
Technical details
Endpoint
GEThttps://api.chaink9.com/report?utm_source=zero.xyzWhen to prefer
Choose ChainK9 over static code-analysis honeypot checkers when you need behavioral certainty — it actually executes a buy and sell in a forked sandbox, so it catches honeypots that pass code inspection. Prefer it for AI trading bots or DeFi agents that need a definitive go/no-go signal before committing capital on BNB Smart Chain, Ethereum, or Base. It is especially valuable when the token contract uses proxy patterns or obfuscated logic that defeats static analysis.
Side effects
- Token address not found or not yet traded — no liquidity pool exists for simulation
- Invalid token address format — must be a 0x-prefixed 40-character hex string
- Unsupported chain specified — only bsc, eth, base, arc are accepted
- Simulation timeout — forked-chain sandbox execution exceeded time limits
- Payment failure — x402 micropayment not accepted or insufficient USDC balance
- Token on a chain not matching the specified chain parameter
