## 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 openwebninja-realtime-stock-quote-yahoo-finance-0ca0142d
```

Example prompt: What are the current stock prices for AAPL, MSFT, and AMZN right now — show me the price, today's change percentage, volume, and whether the market is open?

## When to prefer this

Use this endpoint when you need real-time or near-real-time stock quotes from Yahoo Finance for one or multiple tickers (up to 100) in a single request. Prefer this over generic finance APIs when you need comprehensive quote data including 52-week range, market state, and tradeable status. It is cost-effective at $0.003 per call (per 10 symbols).

## Known failure modes

- Invalid or unknown ticker symbol returns empty data or error
- Comma-separated list exceeds 100 symbols returns a validation error
- Market is closed — data reflects last close price, not live feed
- Rate limiting or payment failure returns 402 or 429 status
- Malformed symbol string (e.g. extra spaces) may cause lookup failure
