Ich bin Programmierer
...dafür bist Du aber ziemlich unbeholfen. Als Programmierer weiß man wie man Suchmaschinen benutzt.
also wo man halt so mal brauch wenn man gern programmiert
...sehr zielführende Definition, dessen was du brauchst...🤔😁
API bedeutet einfach Schnittstelle zum Datenaustausch.
Wenn Du nicht präzisieren kannst, auf welche Art von Daten Du zugreifen möchtest, ist Dir nicht zu helfen...
Es gibt Millionen solcher Schnittstellen.
Nur mal die API für Windows-Desktop : https://learn.microsoft.com/de-de/dotnet/api/?view=windowsdesktop-10.0
oder
OpenStreetmap: https://nominatim.org/release-docs/develop/api/Overview/
oder
Wetter: https://open-meteo.com/
...alles kostenlos... (manchmal muss man nur ein wenig suchen)
Hier mal ein kleines völlig simples Beispiel, wie man mit den Online-APIs von OpenStreetmap und OpenMeteo Wetterdaten für einen Platz abfragt.
