# Token Safety Checker — klymax402

> Token Safety Checker — klymax402 is a paid API for AI agents from klymax402.com, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).

Checks a token contract address for safety risks including honeypot detection, buy/sell taxes, mintability, and overall risk score on Ethereum or Base.

## 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 token-safety-checker-klymax402-e47d5cd6
```

Example prompt: Can you check if the token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 is safe to trade on Ethereum — I want to know if it's a honeypot, what the buy and sell taxes are, and its overall risk score?

## When to prefer this

Use this endpoint when you need a quick, structured safety assessment of a specific token contract before trading, listing, or investing — particularly when you need honeypot detection, tax analysis, and a composite risk score in one call. Prefer this over manual block explorer lookups or generic contract readers when you need DeFi-specific risk flags (honeypot, mintable, proxy) rather than raw bytecode. Best for Ethereum and Base chains.

## Known failure modes

- Address not found on specified chain — found: false returned
- Invalid contract address format — likely 400 error or empty response
- Chain parameter not recognized — may default to Ethereum or return error
- Token contract is unverified — limited data may be returned
- Network timeout or upstream data provider unavailability
- Payment not processed — 402 response if USDC payment fails

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object with: the token name, chain and chainId, risk score (numeric), honeypot flag (boolean), buy and sell tax values, whether the contract is mintable or a proxy, total supply, and holder count — giving a comprehensive safety snapshot of the token.
