## 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 stable-financial-vercel-app-8fff9cbe
```

Example prompt: What's the current price of TSLA, including how much it's moved today and the percent change?

## When to prefer this

Use this endpoint when you need a real-time price snapshot for a single ticker including intraday change metrics. It is ideal for quick point-in-time quotes rather than historical data, batch quotes, or technical indicators. Choose this over generic financial APIs when you need x402 micropayment-compatible access with per-call pricing.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error
- Missing ticker query parameter returns a validation error
- Market closed or outside trading hours may return stale or unavailable data
- Payment not authorized or USDC balance insufficient returns 402 Payment Required
