## 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 x402stock-xyz-7a196512
```

Example prompt: Pull today's biggest percentage gainers for US stocks — I want to see which tickers are up the most, along with their OHLCV and how they compare to yesterday's close.

## When to prefer this

Choose this endpoint when you need a ranked list of the day's top US equity percentage gainers with full OHLCV context in a single call, rather than screening individual tickers or fetching end-of-day snapshots separately. Ideal for market-open scans, momentum strategies, or daily briefings.

## Known failure modes

- Market closed or no data yet for today — may return empty tickers array or stale as_of
- Payment failure (402) if USDC payment header is missing or insufficient
- Rate limiting or service unavailability returning 429 or 5xx
- Outside US market hours may return incomplete intraday data

## How this service works

The day's biggest percentage gainers across US equities, with current and previous-day OHLCV per ticker. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

## Output

A JSON object containing an as_of timestamp, a count, the direction ('gainers'), and an array of ticker objects each with: ticker symbol, absolute change, percentage change, last-updated timestamp, and full OHLCV+VWAP for both the current day and previous day.
