More than widgets

            
Complete services in your own interface

            
Widgets are the fastest way in. With the same Natur-Engine you can also build whole features into your own design – map, route planner, navigation, emergency – without running your own geodata or weather infrastructure.

Much more is possible

            
More widgets on request – from the same building blocks

            
The nine widgets above are just the start. Because the Natur-Engine already knows weather, landscape, paths, places to eat and season, a new widget comes together quickly. We build these ideas for you on request:

  • Rain in the next hoursIs a shower coming? With a radar view around the house.

Your own widget – built on request

                    
None of the widgets quite fits? We build a widget to your wishes. You describe what your guests or customers should see, we send you a draft, and it is embedded like all the others: with two lines of code.

                

                
    
                    
  • Your lookYour colours, your font, your logo – the widget looks like part of your website.
    • 
                    
  • Your contentYour own loops, your starting point, your tips and notes – combined with the data of the engine.
    • 
                    
  • Your combinationSeveral building blocks in one box, in exactly the order your guests need.
    • 
                    
  • Your formatSidebar, banner, full page or info screen in the lobby – in the languages of your guests.

Licences and attribution

            
    
                
  • The Natur-Engine relies on open data whose licences also allow commercial use. The required attribution is in every response in the “attribution” field and must be visible when displayed.
    • 
                
  • In the works: a white-label version without the Natur-Engine branding, for an extra fee. Interested? Just get in touch via the contact form.
    • 
                
  • Paths and places come from OpenStreetMap (ODbL). Displaying individual queries is fine; harvesting whole data sets and passing them on as your own database is not.
    • 
                
  • Assessments are forecasts without guarantee. Safety and edibility are always decided by people; in an emergency, 112 always comes first.

FAQ

            
What does the Natur-Engine API cost?
We discuss terms personally – depending on quota and use. For testing there is a key with a small daily quota.
Do widgets need programming skills?
No. Copy two lines into the website, enter the place – done. The height adjusts automatically.
Do the widgets set cookies or trackers?
No. When displayed, our server receives the usual connection information (IP address, browser) of the visitor; there are no cookies or tracking. Please list the widget as an embedded service in your privacy policy.
Which areas does the Natur-Engine cover?
Weather, forecasts and season for all of Europe; routing, hiking trails and winter data for Central Europe; most detailed in Germany, Austria and Switzerland.
Do I need to credit a source?
Yes. Every response contains an “attribution” field with the text and link that must be visible when displayed. Widgets already include it.
