List page IDs

All Identifier list endpoints return paged lists of IDs rather than full records. The response includes the IDs for the current page and a flag that tells you whether more results exist.
Example response
{
  "id": [336953, 412071, 598204],
  "existujeDalsieId": true
}
  • id — array of entity IDs for the current page.
  • existujeDalsieId — when true, more results exist.

​
Get the next page

If existujeDalsieId is true, more IDs are available. To fetch the next page, send the same request again and set pokracovat-za-id to the last ID from the current response. Because results are ordered by id, the next page starts after that value.
Example request
# First page
curl "https://www.registeruz.sk/cruz-public/api/uctovne-jednotky?zmenene-od=2000-01-01&max-zaznamov=100"

# Next page — use the last id from the previous response
curl "https://www.registeruz.sk/cruz-public/api/uctovne-jednotky?zmenene-od=2000-01-01&max-zaznamov=100&pokracovat-za-id=598204"
Example response
{
  "id": [635005, 635006, 635007],
  "existujeDalsieId": true
}
Continue until existujeDalsieId is false or the id array is empty.

​
Choose a page size

Use max-zaznamov to control how many IDs are returned per page.
SettingValue
Default1000
Maximum10000
During development, a smaller page size such as 100 is often easier to work with.

​
Count remaining records

Before paginating through a large result set, you can check how many records remain using the count endpoints. They accept the same parameters as the list endpoints and return a single number.
Example request
curl "https://www.registeruz.sk/cruz-public/api/zostavajuce-id/uctovne-jednotky?zmenene-od=2000-01-01&pokracovat-za-id=598204"
Example response
{
  "pocetZostavajucichId": 142
}
This is not required for pagination but often used to display progress bars, build logs, or decide whether to continue a sync. For more information, see Remaining counts.
