## 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-3424f338
```

Example prompt: Compare AAPL, MSFT, and NVDA side by side — I want to see their price and day change, market cap, P/E, EPS, revenue, gross and net margins, and dividend yield all in one shot.

## When to prefer this

Use this endpoint when you need a quick multi-metric side-by-side snapshot of 2–3 US stocks in a single API call. Prefer it over fetching individual stock endpoints when the goal is peer comparison, watchlist review, or ranking by fundamentals like margins or P/E. It is more efficient than calling per-ticker endpoints separately and returns a combined view of price, valuation, and profitability metrics together.

## Known failure modes

- Missing or empty tickers parameter returns 400 error
- More than 3 tickers may be unsupported or return partial data
- Unknown or delisted ticker returns null values for most fields with available flag indicating unavailability
- Payment failure (insufficient USDC balance) blocks the call via x402 protocol
- Network timeout if upstream snapshot or fundamentals data is delayed

## 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 an array of rows, one per ticker, each containing: ticker symbol, company name, current price, day change percent, market cap, P/E ratio, EPS, revenue, gross margin percent, net margin percent, dividend yield percent, and an availability flag. Also includes source identifier and as-of timestamp.
