# 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).

Scans an ERC-20 token contract on Base/EVM chains for rug risk, honeypot flags, proxy/owner control, approval risk, and holder/liquidity danger signals, returning a composite 0-100 risk score with verdict

## 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-b016bf6f -d '<json body>'
```

Example prompt: Before I swap into this Base token at 0x1234...abcd, can you run a full risk scan on it — check for honeypot flags, rug risk, owner control issues, and give me the composite 0-100 risk score and verdict?

## When to prefer this

Use this endpoint when an autonomous trading agent needs a pre-trade safety gate before executing a swap, buy, DCA, or memecoin entry on Base or other EVM chains. It is specifically designed for agent-driven trading workflows and provides a composite risk score rather than just raw contract data, making it easier to implement automated pass/fail logic. Prefer this over generic contract explorers when you need a structured, machine-readable risk verdict with multiple signal categories in a single call.

## Known failure modes

- Invalid or unrecognized contract address returns an error response
- Unsupported chain returns a validation error
- Token contract not yet deployed or not ERC-20 compliant may yield incomplete analysis
- Network timeout or RPC node unavailability may cause request failure
- Payment failure (insufficient USDC balance or missing x402 header) blocks the request

## How this service works

Base/EVM token risk scan for autonomous trading agents before swaps, buys, DCA, and memecoin entries. Detect rug risk, honeypot/tax flags, proxy/owner control, approval risk, holder/liquidity danger signals, and return a composite 0-100 risk score with 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 0-100 risk score, a plain-language verdict, and detailed flags covering: honeypot/tax detection, rug risk signals, proxy/owner control indicators, approval risk, and holder/liquidity danger signals for the scanned ERC-20 token.
