# b0x402 Token Safety Scanner

> b0x402 Token Safety Scanner is a paid API for AI agents from b0x402-data.mulberry-boar.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Scans an ERC-20 token contract for honeypot detection, tax rates, and composite risk scoring using Honeypot.is and on-chain data.

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 b0x402-token-safety-scanner-ca52ed1d
```

Example prompt: Is the token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum a honeypot? Give me the risk level, buy and sell taxes, and whether the contract is open source.

## When to prefer this

Use this endpoint when you need on-chain honeypot detection and tax analysis for ERC-20 tokens on Ethereum, Base, BSC, Polygon, or Arbitrum — especially when you need a structured, pay-per-call API that combines Honeypot.is data with live on-chain holder counts and proxy detection without requiring API key management.

## Known failure modes

- Invalid contract address format (must be 0x + 40 hex chars) returns 400
- Unsupported chain identifier returns 400
- Contract address not found on specified chain returns 404 or empty result
- Honeypot.is upstream outage may cause 502 or degraded data
- Insufficient USDC balance or failed x402 payment returns 402

## How this service works

Real-data x402 V2 API on Base. Token safety scanner (Honeypot.is + on-chain) and multi-chain gas tracker. Pay per call in USDC.

## Output

Returns a composite risk verdict (low/medium/high/critical), boolean honeypot flag, numeric risk level (0-4), buy/sell/transfer tax percentages, holder count, whether the contract is open-source and proxy-based, token name and symbol, and specific risk flags raised by Honeypot.is.
