Screen the stock universe by combining optional range filters across datasets: market cap and price, sector and industry, 13F filer count and its change, institutional ownership and the 13F holder signals of the newest computed closed quarter (conviction share, crowding, private-fund adviser ownership, active holders' share change, holder tenure, and price versus the holders' estimated average cost), short interest and days to cover, composite short-squeeze and insider-sentiment scores, net insider buying (90d), the going-concern doubt flag, and daily-refreshed derived metrics (trailing P/E, dividend yield from split-restated TTM cash dividends per share divided by share price, revenue growth YoY, gross margin, average daily dollar volume, TTM net income). A bound on a metric excludes stocks with no data on that axis. Sorted by the chosen metric (default market cap, descending); page walks past the first page and vintages state each dataset's freshness.

Restrict to members of a covered index, by slug or name (e.g. sp-500, "S&P 500", SPX). A name matching no covered index is a 400 listing the covered ones.

Listing markets to screen, as comma-separated ISO country codes (for example GB,FR), or all for every market. Omitted means US.

Sort ascending instead of descending.

Maximum rows to return (default 50, max 200; zero or negative values are rejected, values above the maximum are clamped).

Result page, 1-based (default 1) — combine with limit to walk past the first page. A page past the end returns the last real page (see the response's page field).

Comma-separated list of up to 200 tickers to restrict the screen to, so a caller can score stocks they already hold instead of searching the market. Every other bound still applies. Class-share dots (BRK.B) resolve to the listed form and a secondary listing resolves to its issuer; symbols outside the universe come back in the response's notFound array.

Response format: omit or json for the JSON envelope, csv for a flat CSV file. CSV headers are the stable cols keys rather than display labels, and the envelope's paging metadata rides on the X-Screener-Total-Count, X-Screener-Page, X-Screener-Total-Pages, X-Screener-Not-Found and X-Screener-Not-Found-Count response headers. Any other value is a 400.

Comma-separated CSV column keys (for example pe,de,roic,volatility), applying only with format=csv; passing it without CSV is a 400 rather than a silently ignored parameter. An unknown or empty key list is a 400. Omitted means the default column set, and none means the pinned columns only. Every file starts with four pinned fields, ticker, name, price and marketcap, then one column per key passed; there is no ticker key of its own because the pinned company column emits ticker and name together.
