## 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 basebuilder2-trading-early-buyers-hunter-c8661f2f -d '<json body>'
```

Example prompt: Can you find the early buyers for the token at contract address 0xABC123... — I want to see which wallets got in first and how much they bought?

## When to prefer this

Use this endpoint when you need to identify wallet addresses that purchased a specific token early in its trading history, particularly for alpha research, smart money tracking, copy-trading strategy, or detecting insider activity. Prefer this over generic block explorers when you want pre-processed, ranked early-buyer data without manually parsing transaction histories.

## Known failure modes

- Invalid or unrecognized contract address returns an error or empty result
- Token with insufficient on-chain history may return no early buyer data
- Rate limiting or payment failure (402) if USDC payment is not processed correctly
- Network or RPC errors if the underlying blockchain node is unavailable
- Token launched on an unsupported chain returns an unsupported chain error
