The valuation family — market capitalization, enterprise value, and the price multiples & yields (P/E, P/S, P/B, P/FCF, EV/EBITDA, EV/Sales, earnings yield, FCF yield, dividend yield) — for a company BY TICKER or CIK, computed at read time either AS OF a past date or LIVE off the latest close.

The valuation family for a company, computed at READ time — the ONE part of the fundamentals surface whose value moves with market price. The stored ratio cells carry the price frozen at the last nightly recompute; this endpoint recomputes the price-driven cells (market cap, enterprise value, the price multiples and yields) fresh per request. Two modes on ONE route: omit as_of and you get the LIVE current valuation — the current-period cells valued off the latest close every request, with meta.price_date (and the current cell's price_date) telling you the trade date of that close, so you can see whether it is today or a stale trading day. Pass as_of=YYYY-MM-DD and you get the point-in-time valuation as it stood on that date — the fundamentals in force then (capped to filings the market had seen) paired with the price then; basis=latest uses the restated view, basis=original the as-known-then filing. period is A (default) | Q | TTM; years bounds the window (<= 25). Per-share market prices are NEVER exposed: the price is multiplied into market cap and its magnitude is redacted from every receipt (each cell's inputs records market_price with a null, redacted value) — you receive the multiple, never the underlying quote. Errors: 400 INVALID_PARAM (bad period/years/as_of/basis); 404 UNKNOWN_TICKER (the id matches no US filer); 404 NOT_YET_PARSED (a real filer with no standardized data yet). The endpoint is LIVE and serves both the as-of and the live valuation.
