## 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 stock-price-api-klymax402-com-06022dbc

## When to prefer this

Use this endpoint when you need a quick real-time snapshot of a single stock's price, change, volume, and market cap by ticker symbol. Prefer this over broader financial data APIs when you only need a lightweight quote rather than historical data, earnings, or fundamentals.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty result
- Market closed hours may return stale or last-close data rather than live price
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Network timeout if the upstream market data provider is unavailable
- Delisted or OTC stocks may not be supported
