# EVM Token Safety Analyzer

> EVM Token Safety Analyzer is a paid API for AI agents from 4yearcycle.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Analyzes an EVM token contract address for security risks, honeypot status, tax rates, and other safety signals using GoPlus data

## Facts

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 evm-token-safety-analyzer-3c808f7b
```

Example prompt: Can you check whether the token at 0x6982508145454Ce325dDbE47a25d4ec3d2311933 on Ethereum is safe — specifically if it's a honeypot, what the buy/sell taxes are, and any other elevated risks I should know about?

## When to prefer this

Use this endpoint when you need a fast, structured security summary for any EVM token (Ethereum, Base, BSC, Arbitrum) before trading, investing, or integrating. It aggregates GoPlus security signals into a single call covering honeypot detection, tax analysis, contract flags, and holder distribution — ideal for pre-trade screening in DeFi bots or portfolio tools. Prefer it over manual block explorer checks or broader on-chain analysis tools when you need a single risk verdict quickly.

## Known failure modes

- Token address not found in GoPlus index — returns found:false with no risk data
- Invalid contract address format — rejected by schema validation
- Unsupported chain specified — enum validation error
- Token is newly deployed and not yet indexed — returns found:false
- Network or upstream GoPlus API timeout — HTTP error or empty response

## How this service works

Interactive Bitcoin 4-year halving cycle chart on a polar disc. Live price, 200W MA, Mayer Multiple, RSI, MACD, Pi Cycle and optional paid cycle projections.

## Output

Returns a JSON object with the token's name/symbol/total supply, whether it was found in GoPlus, a list of human-readable elevated-risk findings (e.g. 'transfers can be paused', 'has blacklist function'), honeypot status, buy/sell tax percentages, holder and LP holder counts, top-3 holder percentage, proxy status, mintability, CEX listing status, and GoPlus trust list membership.
