# DESK LEAD x402 – Token Safety Check

> DESK LEAD x402 – Token Safety Check is a paid API for AI agents from desk-x402.desk-x402-gh.workers.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns a GoPlus-powered token safety report for a given ERC-20/BEP-20 token address on BSC or Base networks

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 desk-lead-x402-token-safety-check-2d04c862
```

Example prompt: Can you run a token safety check on the contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on the Base network before I invest?

## When to prefer this

Use this endpoint when an agent needs a quick, pay-per-call token risk assessment without a subscription — ideal for DeFi workflows on BSC or Base that need GoPlus security data at $0.05 per check. Prefer this over full GoPlus direct API integration when operating in an x402 micropayment context or when you need lightweight per-query billing.

## Known failure modes

- Invalid or non-checksummed token address returns validation error
- Unsupported network (not 'bsc' or 'base') returns enum validation failure
- Missing or invalid x402 micropayment header returns HTTP 402 Payment Required
- Token address not found on the specified network may return empty or null report fields
- Cloudflare Worker timeout on upstream GoPlus call

## How this service works

Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.

## Output

A JSON object with an 'ok' boolean, a 'report' object attributed to GoPlus containing security risk fields (e.g. honeypot detection, ownership, blacklist, mint authority, tax info), and a 'product' identifier ('token_safety').
