# DeFi Shield Token Simulation

> DeFi Shield Token Simulation is a paid API for AI agents from defi-shield-hazel.vercel.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Simulates token transactions to detect honeypots, hidden fees, and blacklist or pause mechanisms before interacting with a DeFi token

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 defi-shield-hazel-vercel-app-2bebe73d -d '<json body>'
```

Example prompt: Before I buy any of this token at contract address 0x1234...abcd on Ethereum mainnet, can you simulate a transaction to check if it's a honeypot, has hidden fees, or has any blacklist or pause mechanisms that could trap my funds?

## When to prefer this

Use this endpoint when an AI agent or user wants to assess the safety of a specific token contract before executing a trade, especially for unknown or newly launched tokens. Prefer this over generic contract audits when you need a fast, transaction-level simulation focused specifically on honeypot traps, sell restrictions, hidden fees, and blacklist/pause controls.

## Known failure modes

- Invalid or non-existent token contract address returns error
- Unsupported chain ID results in unsupported network error
- Token contract with non-standard ABI may produce incomplete simulation
- RPC node unavailable causing simulation timeout
- Contract self-destructs or is unverified causing analysis failure

## Output

Returns a simulation report indicating whether the token is a honeypot, any hidden or unexpected fees detected during simulation, whether the contract has blacklist functionality that could block sells, and whether pause mechanisms exist that could freeze transfers — giving an overall safety assessment before trading.
