Dimensions summary
This listing uses a single pricing dimension, Product Access (Units), and is offered at no cost. Subscribing grants you access to the product rather than charging by usage, seat count, or term commitment. There are no tiers, instance sizes, or add-on units to compare. The dimension covers daily short interest and securities financing data, including borrow rates on covered securities. Because pricing is free and structured around one access grant, there is nothing that scales with volume or consumption. You subscribe once to unlock access.
Top-of-mind questions for buyers
One unit grants access to the daily short interest and securities financing dataset. This includes true daily global short interest across covered securities, paired with bid, offer, and last borrow rates on each security. Access is granted per subscription, not metered by query volume, security count, or user seat.
No. The single access unit is offered at no cost and does not scale with usage. Querying more securities, pulling more data, or adding users does not trigger extra charges. There are no tiers or included-amount thresholds, so nothing meters up or down based on consumption.
The dataset covers short interest and securities financing on covered securities. Per the seller, delivery reaches teams through direct API and SFTP feeds, plus cloud data marketplace channels including AWS. For delivery specifics tied to your setup, contact the vendor.
