## 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 api-strale-io-59b78718
```

Example prompt: What is the current stock price, daily change, and volume for AAPL right now?

## When to prefer this

Use this endpoint when you need real-time or near-real-time stock quote data for a publicly traded company identified by its ticker symbol, including support for international exchanges (e.g. VOLV-B.ST). Prefer this over general financial APIs when you need quick per-call pricing with x402 micropayment access and no subscription required.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Delisted or OTC securities may not be found
- Market data feed outage may cause stale or missing quotes
- Missing required 'symbol' query parameter returns a 400 error
- Non-public or private company tickers return no data
