ZYRS public data
================

The smallest real companies listed on the Nasdaq, screened and ranked, with
market cap computed from each company's own SEC filing rather than read off a
screener field. Free, no key, no auth, CORS open.

Why this is not just another screener
-------------------------------------
Screener market-cap fields are wrong for small foreign and multi-class
issuers, because they often cover a single listed share class. Measured on
2026-09-03: the Nasdaq screener put Founder Group (FGL) at $184,458 while the
share count in the company's own 20-F implies $291,830,574. Wrong by about
1,584 times. MGN was out by 17.6x, WHLR by 2.5x.

So this endpoint computes it instead:

    market cap = shares outstanding (SEC XBRL, dei:EntityCommonStockSharesOutstanding)
                 x last sale (Nasdaq screener)

Every row carries the date its share count was filed, plus links to that
company's Nasdaq quote page and its SEC filing index, so you can check any
figure yourself.

Screens applied
---------------
Common and ordinary shares only. Warrants, units, rights, preferreds and
depositary shares are excluded, because they are paper rather than businesses
and you cannot build a position in a company by buying them. Then: last sale
at or above $0.10, at least $25,000 traded per day, computed market cap at
least $50,000, and two sanity screens that reject stale filings (a day's share
volume cannot exceed the shares that exist, and a day's dollar volume cannot
exceed the whole company).
