# ERC20 Honeypot & Transfer Restriction Detector

> ERC20 Honeypot & Transfer Restriction Detector is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Performs a heuristic on-chain honeypot check for an ERC20 token via eth_call, detecting active owner control, transfer restrictions, and sell-prevention mechanisms on Ethereum and Base.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 erc20-honeypot-transfer-restriction-detector-3fce7a76
```

Example prompt: Before I buy, run a honeypot check on this token contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — can I actually sell it later, or does it have transfer restrictions that would trap me?

## When to prefer this

Use this endpoint when you need to assess whether a specific ERC20 token can be resold after purchase — particularly before executing a buy on Ethereum or Base. Prefer this over general token info endpoints when the primary concern is sell-ability, owner control, and transfer restriction traps rather than tax rates or contract age.

## Known failure modes

- Invalid or non-existent contract address returns an error
- Unsupported chain (not Ethereum or Base) returns unsupported network error
- Contract is not an ERC20 token, leading to inconclusive or error response
- RPC node timeout causing a failed eth_call
- Payment not included or insufficient USDC, resulting in 402 Payment Required

## How this service works

Heuristic honeypot and risk check for an ERC20 token via on-chain eth_call - detects active owner control and transfer restrictions that can trap buyers, on Ethereum and Base. honeypot check, honeypot detector, can i sell token, token scam check, rug detection, transfer restriction Accepts payment on Base or Solana — either network works.

## Output

Returns a risk assessment indicating whether the token is a likely honeypot, whether the owner retains privileged control, whether transfer restrictions are active that could prevent selling, and any other on-chain signals suggesting buyer-trapping or rug-pull risk.
