Choose a method
RPO supports local copies by downloading the full register as compressed JSON files. Use it when you need the full register in your own system or want to process many entities at once.| Use case | Best choice |
|---|---|
| Look up a single entity by IČO | REST API |
| Fetch one entity on demand | REST API |
| Build a local copy of the entire register | Local storage |
| Process many entities at once | Local storage |
| Build a search index or analytics pipeline | Local storage |
| Keep your local copy of the register up to date | Local storage |
Find the export files
All files are publicly available at:Understand the export
The export is published in two batch types:Init batch
A full snapshot of the register. Use this to build your initial baseline.| Field | Value |
|---|---|
| File prefix | batch-init/ |
| Filename pattern | init_yyyy-mm-dd_nnn.json.gz |
| Update frequency | Monthly, on the first Saturday of the month |
Example init batch files
Daily batch
Incremental updates containing records added or changed since the previous day.| Field | Value |
|---|---|
| File prefix | batch-daily/ |
| Filename pattern | actual_yyyy-mm-dd.json.gz |

File contents
Each file contains compressed JSON records shaped like the Detail API response, including identifiers, names, addresses, legal form, legal status, activities, stakeholders, statutory bodies, and organization units. Two fields present in the live API are not included in export files:dbModificationDatelicense
Build your local copy
Load into your storage
Insert or upsert records into your database, warehouse, or search index. The record shape follows the Detail API response, so the API reference is useful here.
Review limits
- Export batches are retained for 45 days only — download files before they expire.
- Data refreshes overnight — recent changes may not appear for up to 24 hours.
- Beneficial owner data is not publicly exposed without demonstrating legitimate interest.
