## 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-quote-api-control-operativo-c77f7148
```

Example prompt: What is the current stock price of AAPL, including today's price change and percentage move?

## When to prefer this

Choose this endpoint when you need a quick, paid real-time stock quote for a single ticker symbol via the x402 micropayment protocol, particularly in agentic workflows that already handle USDC payments and need verifiable on-chain transaction receipts for each data fetch.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error response
- Market is closed and real-time data is unavailable, may return null for change fields
- Payment failure or insufficient USDC balance prevents the API call from completing
- Symbol format does not match the required pattern (1–12 uppercase alphanumeric characters)
- Network timeout or upstream data provider outage results in a non-200 response
