## 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 blockscout-top-addresses-by-native-coin-balance-d74e0d69
```

Example prompt: Show me the top 20 addresses holding the most native coins on Ethereum mainnet (chain ID 1), sorted by balance descending.

## When to prefer this

Use this endpoint when you need a ranked list of top native coin holders (rich list / whale list) on a specific blockchain supported by Blockscout. It is ideal for on-chain wealth distribution analysis, whale monitoring, and rich-list pagination. Prefer this over general address search endpoints when the specific goal is ranking by native balance rather than looking up a known address.

## Known failure modes

- Invalid or unsupported chain_id returns a 404 or empty result
- Malformed pagination cursors (fetched_coin_balance, transactions_count, hash) cause unexpected results or errors
- Rate limiting or payment failure returns 402 or 429
- Very new or low-activity chains may return sparse or empty lists

## How this service works

Access to api/v2/addresses. List addresses holding native coins sorted by balance - top accounts

## Output

A paginated list of blockchain addresses ranked by native coin balance, each entry including the address hash, current native coin balance, transaction count, and metadata needed for cursor-based pagination to the next page.
