Unlock a detailed view of short availability. This endpoint provides rich and actionable insights into how many shares are available to borrow for short selling, helping assess market liquidity and borrowing pressure.

This API returns data for multiple stocks — every constituent of a market index, or of one of your own universes — for the specified date.

Available Data Points:

• Date: The specific date for which the data is retrieved (YYYY-MM-DD format).
• Exchange Symbol: Symbol of the exchange where the security trades.
• Ticker: The ticker symbol associated with the security.
• Company Name: The name of the company issuing the security.
• 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.
• Short availability shares: The estimated number of shares available to borrow for short selling, based on market utilization and reported availability.
• Short availability percentage: The availability shares expressed as a percentage of estimated short interest, indicating how much of the short demand could be covered by borrowable supply.
