## 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 saylor-innovations-stock-quote-api-b7992d77
```

Example prompt: What's the current stock price of AAPL right now?

## When to prefer this

Use this endpoint when you need a quick, low-cost real-time stock quote for a single ticker symbol and are operating in an x402 micropayment-enabled environment. It is ideal for agents that need to look up equity prices on demand without subscribing to a full-featured financial data platform.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty response
- Market closed periods may return stale or last-close data rather than real-time quotes
- Rate limiting or payment failure (x402) if USDC payment is not processed correctly
- Network timeout if upstream market data provider is unavailable
