## 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 chainquery-bitcoin-rich-list-db30322f
```

Example prompt: Show me the current Bitcoin rich list — the top 10 addresses by balance from ChainQuery's latest on-chain UTXO snapshot, including any labels for who those wallets belong to.

## When to prefer this

Use this endpoint when you need a quick, no-API-key lookup of the top 10 Bitcoin addresses by balance with human-readable labels, paid per-call via x402. Prefer this over exchange APIs or blockchain explorers when you want independent, Bitcoin-native on-chain data without account registration, and when weekly snapshot freshness is acceptable.

## Known failure modes

- Payment rejected or insufficient USDC balance — x402 payment required at $0.01 per call
- Snapshot not yet refreshed — data may be up to 7 days old
- Rate limiting if too many unpaid requests are attempted
- Network or service downtime returns 5xx errors

## How this service works

ChainQuery Bitcoin Intelligence: independent Bitcoin-native on-chain data over x402, no API key. Top 10 addresses by balance from the weekly UTXO-set snapshot, with labels.

## Output

A ranked list of the top 10 Bitcoin addresses by balance, drawn from ChainQuery's weekly UTXO-set snapshot. Each entry includes the address, its BTC balance, any known label (e.g. exchange, miner, custodian), and a timestamp indicating when the snapshot was taken.
