## 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 alpha-vantage-top-gainers-losers-aa93df7a -d '<json body>'
```

Example prompt: What are today's top gaining and losing US stocks? Show me the biggest movers with their percentage changes and trading volume.

## When to prefer this

Use this endpoint when you need a snapshot of the day's biggest US equity market movers — the stocks with the highest gains, steepest losses, or most active trading volume. Ideal for daily market briefings, trading alerts, or screening for volatile stocks. Prefer this over individual time-series endpoints when you want a broad market-wide view of top movers rather than data on a specific stock.

## Known failure modes

- Market closed or outside trading hours may return stale or empty data
