Get latest US closing-price snapshots

Returns each stock's closing price for its latest trading day, at most one row per ticker, with date as that trading day. Prices are unadjusted and updated after market close; this is not a real-time quote. Row order is not declared in the contract, so match rows to the request by the ticker field, not by position. US common stock only: if any ticker cannot be resolved or is non-US, the whole request returns 404 rather than returning what it can and silently dropping the rest. For historical prices use /prices-historical.
