The history, all of it, for every market

Why we built it

Historical price data has two habits that make it less useful than it looks. It stops at the daily close, which hides the open, the gap and the hour that actually moved a stock. And it stops at the border of one country, so a study across markets starts with a reconciliation project. DataCedar removes both: one minute bars for every listed stock and index it covers, on every exchange it covers, in one schema.

The pipeline is deliberately small and durable: collectors that capture every session and pull daily history back to first listing when a symbol comes online, a columnar store for the archive, and one API in front of it. Coarser frames are rolled up from the minutes rather than sourced separately, which is why they always agree.

What buyers can inspect before subscribing

Every symbol page is public and states its own dates. The free Explorer tier serves a year of daily bars and a week of minute bars through the same endpoint the paid plans use, so the schema you validate is the schema you will ship against. Coverage per exchange is on the markets page; the contract is in the API reference.

Limits we state explicitly

These are source attributed bars for research, screening and backtesting. They are not a consolidated exchange feed and should not be used for best execution reporting or regulatory record keeping. Minute history starts at the capture date for each symbol and is not backfilled. Those boundaries are part of the product, because a buyer should be able to decide whether the archive fits a study before paying.
