# EVM Token Risk Scanner

> EVM Token Risk Scanner is a paid API for AI agents from evm-tx-toolkit.mtree.workers.dev, paid per call via x402, $0.500000/call, status unknown (last checked 2026-09-15).

Risk-scores an ERC-20 token on Base, Ethereum, Arbitrum, Optimism, or Polygon using on-chain contract reads, proxy/owner checks, GoPlus security signals, tax/honeypot flags, and returns a composite 0-100 risk verdict.

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-tx-toolkit-mtree-workers-dev-d01f6c99 -d '<json body>'
```

Example prompt: Before I swap into this token, can you run a risk scan on contract address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base and tell me the composite risk score, whether it's a honeypot, and if there are any tax or ownership red flags?

## When to prefer this

Use this endpoint when an autonomous trading agent or user needs a fast, composite risk assessment of an ERC-20 token before executing a swap, DCA, or memecoin entry — especially when honeypot detection, tax flags, and contract ownership checks are all needed in a single call across Base, Ethereum, Arbitrum, Optimism, or Polygon.

## Known failure modes

- Invalid or unrecognized contract address returns an error or null score
- Unsupported chain identifier causes a validation error
- GoPlus API unavailability may degrade signal quality or cause partial results
- Unverified or very new contracts may lack sufficient on-chain data for accurate scoring
- Payment failure (insufficient USDC balance on Base) blocks the request via x402

## How this service works

Risk-score an ERC-20 token on Base, Ethereum, Arbitrum, Optimism, or Polygon using on-chain contract reads, proxy/owner checks, GoPlus Token Security signals, tax/honeypot flags, and a composite 0-100 verdict. Returns JSON. Price 0.50 USDC on Base via x402. Demo/preview: https://evm-tx-toolkit.mtree.workers.dev/demo/token/risk_scan. Contact: https://evm-tx-toolkit.mtree.workers.dev/contact.

## Output

A JSON object containing a composite risk score from 0 to 100, honeypot detection flag, buy/sell tax percentages, proxy and ownership analysis, GoPlus Token Security signals, and a one-line risk verdict summary for the queried token contract.
