## How to call it through Zero

```sh
zero fetch --capability openwebninja-stock-time-series-8cd9fd89
```

## When to prefer this

Use this endpoint when you need historical stock price data with time-series granularity and key market events for a specific ticker and period. Prefer this over generic finance APIs when you need both price history and contextually significant events bundled together in a single response.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty data
- Unsupported period value causes a validation error
- Invalid language code may default to English or return an error
- Network/payment issues with x402 protocol result in 402 Payment Required
- Rate limiting or quota exhaustion returns an error response
