## 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 agenttoll-base-token-safety-check-b5224298
```

Example prompt: Before I buy this token, can you run a full safety check on 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base — I want to know if it's a honeypot, what the buy/sell taxes are, whether the liquidity can be pulled, and what the deployer's wallet history looks like?

## When to prefer this

Use this endpoint when you need a quick, multi-signal token safety assessment before executing a buy on Base. It is specifically designed for Base network tokens and bundles honeypot simulation, tax checks, contract verification, deployer profiling, and liquidity risk into a single call — making it ideal for trading bots, DeFi agents, and research workflows that need to gate trades on safety signals without calling multiple separate APIs.

## Known failure modes

- Invalid or malformed contract address returns a 400 error
- Address is a valid Ethereum address but not a token contract on Base (EOA or non-token contract) may return empty or error response
- Token so new it hasn't been indexed yet may return incomplete data
- Payment not received or insufficient USDC results in 402 Payment Required
- Rate limiting or upstream RPC unavailability may cause 503 responses

## How this service works

Token safety check for a Base token before you buy - is it a honeypot, is it a rug: a simulated buy and sell, buy and sell tax, contract verification, owner privileges, holder concentration, whether anyone can still pull the liquidity, and who deployed the contract - a token shipped from a wallet with a handful of transactions is the shape most rugs share

## Output

Returns a structured safety report including: honeypot detection result (simulated buy/sell success), buy and sell tax percentages, contract verification status, owner privilege flags, holder concentration metrics, liquidity withdrawal risk, and deployer wallet profile (transaction count and risk signals)
