API


The data in this application can also be accessed in JSON format with direct requests to an API. Use the following URL to access all (public) dates.

https://www.xronos.ch/api/v1/data
      

You can also filter the data with this interface to only access the subsets relevant for you. With the following URL you get - for example - only one date with the Lab Number AAR-1847.

https://www.xronos.ch/api/v1/data?query_labnr=AAR-1847
      

The | ("pipe") operator allows you to combine multiple filter keys. | represents a logical OR. That means the following URL will give you both dates AAR-1847 and KN-2506.

https://www.xronos.ch/api/v1/data?query_labnr=AAR-1847|KN-2506
      

You can also combine multiple filter criteria by adding filter parameters to the URL with the & ("and") operator. The parameters are combined with a logical AND. The following query will therefore give you all dates measured on charcoal from Germany.

https://www.xronos.ch/api/v1/data?query_country=Germany&query_material=charcoal
      

Heres a list of the available filter criteria:

  • query_labnr
  • query_site
  • query_site_type
  • query_country
  • query_feature
  • query_material
  • query_species
