## 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 market-movers-gainers-losers-90e3e5d6
```

Example prompt: Show me the top 20 biggest stock market gainers and losers from today — I want tickers, current prices, and how much each has moved in percent.

## When to prefer this

Choose this endpoint when you need a broad market-wide scan for the biggest price movers of the current trading day, without targeting a specific ticker. It is ideal for morning briefings, momentum screening, watchlist building, and daily market summaries. Prefer it over ticker-specific endpoints when the user wants to discover which stocks are moving rather than analyze a known stock.

## Known failure modes

- Yahoo Finance data unavailable or delayed — returns stale or empty data
- limit parameter exceeds max of 25 — may return error or cap results at 25
- Called outside market hours — may return previous session's final movers or partial data
- Rate limit or payment failure — returns 402 or 429 error

## How this service works

Day's biggest gainers and losers screened from the entire market, live from Yahoo Finance. Each mover includes ticker, company name, current price, intraday change amount and %, and volume — the market context every trader needs. Not ticker-specific. Supports optional limit per list (default 10, max 25). $0.01/call.

## Output

Returns two ranked lists — top gainers and top losers — each containing ticker symbol, company name, current price, intraday dollar change, intraday percentage change, and trading volume. Default is 10 entries per list, configurable up to 25.
