It might be worth setting up a database on AWS or Google Cloud or Azure or somewhere (I am partial to PostgreSQL). It is fairly straightforward to do the setup (lots of good docs out there) and then you are in control. Further, as long as your data size is reasonable, you will probably land well within the free tier and enjoy your own class-focused database for free!
There are some open datasets out there, on AWS for instance: https://registry.opendata.aws/
They vary in how they are accessed, though.
