## 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 evm-rich-list-67b5f35b -d '<json body>'
```

Example prompt: Show me the top 20 addresses holding the most ETH on Base, including their names and transaction counts.

## When to prefer this

Use this endpoint when you need a ranked leaderboard of native coin holders on a specific EVM chain with enriched metadata (labels, ENS, contract flags). Prefer this over raw RPC calls when you want pre-labeled, sorted results without writing custom indexing logic. Best suited for whale monitoring, on-chain research, DeFi analysis, or compliance screening of top holders.

## Known failure modes

- Invalid or unsupported network enum value returns an error
- Requesting more addresses than available on-chain data returns a truncated list
- Network temporarily unavailable from Blockscout data source causes delayed or empty response
- Missing required 'network' field in body returns validation error

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing the queried network name, data source attribution (e.g. Blockscout URL), and an array of the largest accounts ordered by native balance descending. Each account entry includes: wallet address, native coin balance, human-readable name or label if known (exchanges, bridges, contracts), ENS name if available, a boolean indicating if it is a contract, transaction count, and a scam flag.
