## 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 kaspa-address-balance-network-status-da1be1d7 -d '<json body>'
```

Example prompt: What's the current KAS balance and USD value for the Kaspa address kaspa:precqv0krj3r6uyyfa36ga7s0u9jct0v4wg8ctsfde2gkrsgwgw8jgxfzfc98, and how many transactions has it made?

## When to prefer this

Use this endpoint when you need on-demand Kaspa (KAS) address balance and USD valuation, or Kaspa network statistics. It is purpose-built for the Kaspa blockchain and pulls both on-chain data and live price feeds in a single call, making it ideal for agents that need KAS-specific data without integrating multiple sources.

## Known failure modes

- Invalid or malformed Kaspa address returns an error or null fields
- Network unavailability of the public Kaspa API causes request failure
- Price feed from DefiLlama may be delayed or unavailable, resulting in null USD values
- Missing required 'input' wrapper object causes schema validation error

## Output

Returns a JSON object with the Kaspa address queried, KAS balance, USD value, number of transactions, and current KAS price in USD. If no address is provided, returns Kaspa network-level metrics including block count, difficulty, hashrate, and supply figures.
