## 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 pulsescanner-token-richlist-03251f16
```

Example prompt: Show me the top 50 largest holders of the token at address 0xA1077a294dDE1B09bB078844df40758a5D0f9a27 on PulseChain, sorted by balance.

## When to prefer this

Use this endpoint when you need to identify the top holders of a specific token on PulseChain (chain id 369) ranked by balance — ideal for whale analysis, supply concentration checks, insider wallet identification, or on-chain governance research. Prefer this over generic blockchain explorers when you need structured, paginated richlist data via a simple API call with micropayment access.

## Known failure modes

- Invalid or non-existent token contract address returns empty list or 404
- Malformed address (not a valid checksummed ERC-20 address) results in a 400 error
- Token exists on a different chain (not PulseChain chain id 369) returns no data
- Payment not attached results in 402 Payment Required
- Exceeding API rate limits or invalid cursor returns an error
- Token with no holders or newly deployed contract may return an empty richlist

## How this service works

## Output
