## 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 token-early-buyers-lookup-6a017af3
```

Example prompt: Show me the earliest buyers of token contract 0xABC123... on Base — I want to see who sniped it at launch, their wallet labels, and what order they got in.

## When to prefer this

Use this endpoint when you need to identify who bought a token earliest — by on-chain transaction order — and want wallet labels to classify them as snipers, insiders, or smart money. Prefer this over generic transfer-tracing endpoints when the specific goal is ranking first buyers and studying early entry patterns for a token launch.

## Known failure modes

- Invalid or non-existent token address returns an error or empty result
- Token with no buy history on the specified chain returns empty list
- Missing API key or invalid x402 payment returns 402 or 401 unauthorized
- Unsupported chain identifier returns an error
- Very new token with no indexed transactions may return incomplete data

## How this service works

The earliest buyers of a token in chain order with wallet labels - reveals who got in first, the early smart money, insiders or snipers, so agents can study entry patterns and follow early movers, from data behind an API key. early buyers, first buyers, who bought first, token snipers, early movers, smart money entry, insider buyers

## Output

An ordered list of the first wallets to buy the token, sorted by chain order (block/tx position), each with the wallet address, any known label (e.g. sniper bot, known insider, MEV bot), the buy timestamp, block number, and transaction hash so you can reconstruct the early entry pattern.
