Elevate your data-driven strategies with ORTEX’s Shares Outstanding API. Gain real-time visibility and full history into how many shares a company has issued, or when they last issued more shares. With reliable coverage and frequent updates, you’ll have the insights needed for trend analysis, portfolio weighting, or fundamental research—all delivered through a seamless and developer-friendly endpoint. Whether you’re a quantitative fund, an active trader, or a financial data vendor, ORTEX’s Shares Outstanding API provides the accuracy and depth to keep you ahead of the market.

Available Data Points:

• Date: Date from which the shares are outstanding.
• Shares Outstanding: Number of shares outstanding.

Resolving renamed, delisted or moved tickers (US only)

ticker_as_of_date (yyyy-mm-dd) selects which instrument the ticker refers to, as of that date. It changes instrument resolution only — it does not filter the returned data (the date range is still from_date / to_date). Tickers get reused, renamed and delisted, so by default a ticker that is no longer active returns 404 and a recycled ticker resolves to today's owner. With this set, the URL path exchange is ignored and all US exchanges are searched for whoever held the ticker on that date, letting you pull history for a company that has since changed ticker, delisted, or moved exchange. Omit it for the current, unchanged behaviour; a non-US instrument with this parameter returns 400.
