31 datasets built from public market records: what the statistical agencies and central banks release, what the CFTC reports about futures positioning each week, what companies, insiders and funds file with the SEC, and what the exchanges publish. Each page dates its figures, and the numbers on it can be pulled through the same free API.

Fund portfolios
The quarterly 13F holdings of well-known investment managers, with what each one bought and sold.

Our standards
- Primary sources
- Datasets come from the agency, the exchange or the issuer itself wherever the original is available, and each page names its source. Each hub page also says how often the data updates and how far back it goes.
- Nothing invented
- We publish what the source publishes. When a page shows a figure we calculate, like a net position or a year-over-year rate, it says so.
The rules in full: Editorial policy.
How to reach us
XOOMAR publishes under the company name, not a byline. The company stands behind every number, and every dataset page names its source. Questions about the data, the API or a page go to the same address.
