# ChainK9 Token Risk Check API

> ChainK9 Token Risk Check API is a paid API for AI agents from api.chaink9.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30).

Runs a live sandbox simulation of buying and selling a token on BNB Smart Chain, Ethereum, or Base to detect honeypots and other token risks before trading

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability chaink9-token-risk-check-api-4b3359c9
```

Example prompt: Before I buy, run a sandbox risk check on the BSC token at 0x0e09fabb73bd3ade0a17ecc321fd13a19e81ce82 — actually simulate a buy and sell to see if it's a honeypot or has hidden taxes.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
