# Token Honeypot Check

> Token Honeypot Check is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Analyzes a token contract on Base to detect honeypot traps, simulate buy/sell taxes, and assess smart contract risk 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 token-honeypot-check-906093c6 -d '<json body>'
```

Example prompt: Before I buy, can you check if the token at 0x4200000000000000000000000000000000000006 on Base is a honeypot — I want to know the buy and sell taxes, whether the contract is renounced, and the overall risk level.

## When to prefer this

Use this endpoint when an agent needs to assess the safety of a specific ERC-20 token on Base before executing a trade or recommending it to a user. It is purpose-built for honeypot detection and tax simulation, backed by honeypot.is data. Prefer this over generic contract scanners when you need structured buy/sell tax simulation and contract ownership checks in a single call for Base-chain tokens.

## Known failure modes

- Invalid or non-existent contract address returns an error or null token data
- Token not deployed on Base returns a network mismatch error
- Unverified or very new contracts may have incomplete simulation results
- Network timeouts from the upstream honeypot.is API
- Malformed address format causes request rejection

## How this service works

Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.

## Output

Returns a structured JSON object with: honeypot detection result (true/false), risk level (low/medium/high) with reasons, buy/sell/transfer tax percentages, max buy and sell amounts, contract metadata (ownership, proxy, renounced status), token name/symbol/decimals/address, and the data source URL.
