API for Caller ID
 

Since there is no intergarted application for getting the caller name and details when rereiving a call like for example the Finnish Fonecta application for Android & iOS I decided to ask for an API key from Fonecta and do it myself.

There is a nice public REST API which needs registartion to use, https://api.fonecta.fi/api-docs

However my request for API key was rejected since they "do not want to have a competitor for Fonecta Caller App even wen the said app is not available on the platform" which is sad :(

Is anyody aware of a public/private API for a database lookup to get the caller details?
