# x402 Agent Tools – Base Token Risk Scanner

> x402 Agent Tools – Base Token Risk Scanner is a paid API for AI agents from x402-agent-tools.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-01).

Analyzes an ERC-20 token contract on Base mainnet for security risks, honeypot detection, sell taxes, and liquidity metrics, returning a risk score and 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 x402-agent-tools-base-token-risk-scanner-390f29f3
```

Example prompt: Before I swap into this token, can you run a risk check on the Base contract 0x8335...2913 and tell me if it's a honeypot, what the sell tax is, and what the overall risk verdict is?

## When to prefer this

Use this endpoint when an agent needs a quick, pay-per-call token safety assessment on Base mainnet without setting up API keys or accounts. Ideal for DeFi trading bots, portfolio monitors, or user-facing agents that need to vet tokens before swaps. Prefer over self-hosted GoPlus integrations when simplicity and per-call USDC micropayment billing are priorities.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty findings
- Token not indexed by GoPlus returns limited or no security data
- Non-Base-mainnet addresses may return incorrect or no results
- Payment failure via x402 results in 402 response with no data
- Rate limiting or Vercel cold start may cause latency spikes

## How this service works

Pay-per-call tools for AI agents. USDC on Base or Solana via x402 v2; no keys, no accounts.

## Output

Returns a JSON object with the chain name, contract address, a summary object (numeric risk score 0–100, verdict string like 'Low risk', and an array of findings with text and severity level), a security object (symbol, sell tax percentage, honeypot boolean), and a liquidity object (total liquidity in USD).
