## 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-compare-multi-stock-7f42ab1b
```

Example prompt: Compare AAPL, MSFT, and NVDA side by side — I want to see their price, P/E ratio, EPS, revenue, gross and net margins, and dividend yield all at once.

## When to prefer this

Use this endpoint when you need to compare 2–3 US stocks simultaneously on both price and fundamental metrics in a single API call. It is purpose-built for peer or watchlist comparisons and returns a comprehensive set of financial data per ticker. For a single stock, the cheaper /api/v1/quote/{ticker} endpoint is preferred. For more than 3 tickers, a different bulk data source should be used.

## Known failure modes

- Invalid or unrecognized ticker symbol returns null values or missing rows
- More than 3 tickers passed may be rejected or truncated
- Network timeout on Vercel cold start causing delayed response
- Stale or missing data for thinly traded or recently delisted stocks
- Payment failure (402) if USDC balance is insufficient

## How this service works

Compare 2 to 3 US-listed stocks side by side (peer or watchlist comparisons). Pass a comma-separated list via `?tickers=AAPL,MSFT,NVDA` (1 to 3 symbols). Returns price and day change, market cap, P/E, EPS, revenue, gross and net margins, and dividend yield per ticker. Built for multiple stocks — for a single stock, `/api/v1/quote/{ticker}` is cheaper.

## Output

Returns a JSON object with a rows array where each entry corresponds to one ticker and includes: ticker symbol, company name, current price, day change percent, market cap, P/E ratio, EPS, trailing revenue, gross margin percent, net margin percent, dividend yield percent, and an availability flag. Also includes source attribution, timestamp (as_of), and count of tickers returned.
