## 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 x402-apis-gold-price-lookup-529883ff
```

Example prompt: What's the current price of 24K gold in USD? Also show me 18K and 22K if you can.

## When to prefer this

Use this endpoint when an agent needs live or near-live gold commodity prices across multiple karat purities and international currencies, especially when no API key or account signup is desired — just pay $0.005 USDC per call via x402 protocol. Prefer this for quick spot-price checks in markets like UAE, India, Pakistan, Philippines, Saudi Arabia, Egypt, or standard Western currencies.

## Known failure modes

- Payment not received — returns HTTP 402 requiring x402 micropayment before serving data
- Invalid karat value — returns error if karat not in accepted set (24K, 22K, 21K, 18K, all)
- Unsupported currency — returns error if currency code not in supported list
- Data source unavailable — upstream gold price feed may be temporarily unreachable
- Network/server error — Vercel deployment may return 500 on transient failures
