# Onchain Honeypot Detector

> Onchain Honeypot Detector is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Detects whether a given blockchain address is a honeypot smart contract designed to trap funds

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 onchain-honeypot-detector-3262ef55
```

Example prompt: Can you check if the contract at 0x1234567890abcdef1234567890abcdef12345678 is a honeypot before I buy any tokens?

## When to prefer this

Use this endpoint when an AI agent or DeFi bot needs a quick, cheap ($0.01 USDC) automated check on whether a smart contract address is a honeypot before executing a trade or interaction. Prefer this over manual audits when speed and cost matter in automated pipelines. Best suited for pre-trade safety gates, portfolio screening workflows, or user-facing safety advisories in crypto apps.

## Known failure modes

- Invalid or malformed contract address returns an error
- Address not found on supported chain returns empty or error data
- Network timeout or upstream node unavailability
- Payment failure via x402 prevents request from being processed
- Address query param missing results in incomplete request

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a status field indicating success, a data object containing honeypot analysis results for the queried address, and an roi_proof field with compression metadata. The data object contains the honeypot detection verdict and associated risk signals for the queried contract address.
