## 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 trapcheck-brief-4c7fc6e3
```

Example prompt: Can you give me a plain-English risk brief on the PEPE token — I want to know the current price action, liquidity situation, any red flags, and what the overall risk level is?

## When to prefer this

Use TrapCheck Brief when you need a fast, human-readable risk summary of a crypto token without deep on-chain simulation — ideal for quick pre-buy checks, portfolio audits, or surfacing red flags like ATH drawdown, liquidity issues, or supply dilution in plain English. Prefer the sibling TrapCheck honeypot endpoint when you need on-chain simulation of trades, tax detection, or owner privilege analysis.

## Known failure modes

- Unknown token name or ticker returns an error or empty result
- Invalid or unrecognized contract address causes lookup failure
- Coingecko or underlying data source unavailability leads to stale or missing price data
- Payment not received (x402 protocol) results in 402 response before analysis is returned
- Ambiguous token name matching multiple assets may return results for the wrong token
