API Enterprise

Region-wide short-availability snapshot for a single date. One request returns, for every covered instrument in the requested region, how many shares are available to borrow for short selling — helping you assess market liquidity and borrowing pressure at scale.

Built for enterprise consumers: a single call replaces a per-ticker fan-out, the response is uncharged (no credits), and every row carries the full instrument-identity block so it can be joined straight onto your own security master.

Available Data Points:

• Date: The specific date for which the data is retrieved (YYYY-MM-DD format).
• Company: The name of the company issuing the security.
• Ticker: The ticker symbol associated with the security.
• Operating MIC: The operating Market Identifier Code of the security.
• MIC: The Market Identifier Code (MIC) for the traded security.
• ISIN: The International Securities Identification Number for the security.
• FIGI: The Financial Instrument Global Identifier.
• Share Class FIGI: The Financial Instrument Global Identifier for the share class.
• Ortex Company ID: Unique id for a company.
• Ortex Security ID: Unique id for a security issued by a company.
• Ortex Tradable item ID: Unique id for a listing of a security.
• Ortex Tradable item main indicator: Indicates if the trading item is the main trading item for the security.
• Tradable Item Currency: The currency of the tradable item.
• Exchange Country: The country location of the exchange.
• Split Ratio: Cumulative split ratio applied to adjust share counts to today's terms.
• Short Availability Percentage: The availability shares expressed as a percentage of total estimated short interest, indicating potential borrow supply relative to demand.
• Short Availability Shares: An estimate of how many shares are currently available to borrow for shorting.

Region and date

Use region to select the universe (a region name, an ISO-2 country code, or "ALL"; defaults to US) and date to select the snapshot day (defaults to the latest available). split_adjusted=false returns as-was share counts instead of values adjusted to today's terms.

Try it out! You can test the API with the trial key TEST. Simply include it in your request headers; either here, or add the header "Ortex-Api-Key": "TEST" to your http request.

Trial key restrictions: Trial keys may be limited to a specific date range and set of regions. Requests outside the allowed regions or entirely outside the allowed date range are rejected; a date window that partially overlaps the allowed range is trimmed to it, reported in meta.restriction.
