Introduction
An overview of the data in the API, where it comes from and what it is mainly used for.
The Firmainfo API brings Swedish company information together behind a single REST interface. You can work with registry data, annual accounts, boards, workplaces, insider trading, short positions and trademarks without building one integration per source.
Available data
| Dataset | Approximate size | Updated |
|---|---|---|
| Companies | 3.5 million company and business records | New limited companies hourly, the full registry weekly |
| Annual reports | 3.0 million filings from 578,000 companies | Hourly |
| Workplaces | 1.4 million locations from 772,000 companies | On import, no promised cadence |
| Board positions | 1.2 million reported roles | With new annual reports |
| Insider trading | 165,000 PDMR transactions from 2016 onwards | Every minute |
| Short selling | 39,000 position observations from 2010 onwards | Every three minutes |
| Trademarks | 600,000 marks with 6.5 million events | On import, no promised cadence |
The cadences vary by source, not by plan — every plan gets the same data just as fast. Frequently asked questions has the full picture, including how often each source publishes. Current coverage figures are available from the public /metadata/data-coverage resource.
What the API is good for
Basic registry data is only the starting point. Our clearest value lies in the combination of detail, linkage and update frequency.
- Fast market feeds. Insider trading is checked every minute and short positions every three minutes. Records are linked to the right company using ISIN and LEI among other identifiers.
- Detailed accounts. An annual report can carry up to 215 structured fields covering notes, employee data, pledged assets, leasing and share classes.
- Fuller trademark history. Records from the Swedish Patent and Registration Office are supplemented with registered events across the whole life cycle of a case.
-
Freshness you can check yourself. The public
/statusresource shows when each of our main feeds last succeeded.
