This listing is offered at no cost. It has a single pricing dimension with no configurable quantities, tiers, or usage add-ons. You access the dataset directly without any commitment term or metered billing. Because the product is free, pricing does not scale with usage, users, or history depth. There are no separate charges tied to this listing. This gives you a sample of US equity trade and quote data for a defined 2020 group of securities without a purchase decision.
Top-of-mind questions for buyers
What data does this free sample actually include?
You get US equity trade and quote data for a defined 2020 group of securities, delivered in CSV format. It is a sample drawn from the full tick-level consolidated feed, which covers trades and NBBO quotes across US equity exchanges. This free listing limits coverage to that fixed 2020 group rather than the full universe.
Are there exchange fees or other charges tied to this free CSV sample?
No. This listing is offered at no cost, and historical data carries no exchange fees. The seller notes exchange fees apply only to real-time streaming feeds, not to historical archives. Since this is a free historical CSV sample, you pay nothing to algoseek and owe no exchange licensing fees for it.
Does the free sample update over time or grow with usage?
No. This free listing covers a fixed 2020 group of securities and does not scale with usage, users, or history depth. Daily automated updates and the full multi-year archive apply to the seller's paid historical datasets, not to this free CSV sample. What you access stays fixed to that 2020 dataset.
