## 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 eth-to-usd-converter-x402node-13f49ec7
```

Example prompt: What's 2.5 ETH worth in US dollars right now — can you give me the live conversion?

## When to prefer this

Use this endpoint when you need a live ETH-to-USD price conversion with a specific amount and want a structured response including the rate, result, timestamp, and source. It is purpose-built for ETH/USD and simpler to call than a generic multi-currency forex endpoint when only Ethereum conversion is needed.

## Known failure modes

- Invalid or non-numeric amount parameter returns an error
- Upstream price feed unavailable causes stale or missing data
- Rate limiting if called too frequently
- Payment failure ($0.004 USDC) blocks the request
