## 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 basebuilder-trading-is-honeypot-contract-check-c8337884 -d '<json body>'
```

Example prompt: Before I buy any of this token, can you check if the contract at 0x4e9e3f8e1b2a3c4d5e6f7a8b9c0d1e2f3a4b5c6d on Base is a honeypot — I want to know if I'll actually be able to sell it later.

## When to prefer this

Use this endpoint when a user wants to vet a specific token or smart contract before trading or investing, particularly on EVM-compatible chains like Base. Prefer this over general contract audits when the specific concern is honeypot mechanics — i.e., whether a token can be sold after purchase.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract not found on specified chain returns not-found error
- Network congestion may delay on-chain analysis
- Newly deployed contracts with no trade history may return inconclusive results
- Unsupported blockchain network returns unsupported chain error
