Simple java rest api for real state

Hello, im looking for a java microservices expert, the idea is to create an API that provides "real time" information. for this project u should use a simple mongodb, which where store all the data consumed from the next 2 apis (they are free with 200 req. month per email):
https://rapidapi.com/apidojo/api/idealista2
https://rapidapi.com/scraperium/api/fotocasa1

So the goal is create API gateway, storing the data in mongodb, but should be stored everyday for a concrete region in spain.

there is a list of few tasks to do:
-Project should use spring boot
-should use docker
-mongodb as database
-use cron as automatize external api calls (mentioned above)
-swagger will be a plus
