The German Federal Ministry of Health and the Robert Koch-Institut operate a web form which you have to fill out when you enter Germany from a COVID-19 high-risk area.
I had to submit my data, so I took a glimpse at what it does in the background.
You can check if your local health authority has a pubkey by asking the api endpoint for it. Have fun:
@vidister Thanks for the analysis. Indeed sounds very good!
Great to see some good news about digitalisation in Germany, too.
@vidister Welp just checked my zip code and there's a name: CLEAR. Seems like no keys for my region :(
@vidister hmmm, it seems Berlin and Braunschweig (38100) are handled by the same office, at least they have the same key and "GA number" in the API
