Hi, EPSG.io API endpoints will be deprecated after the 1st of February 2025: https://epsg.io/docs#migration This will affect multiple projects of yours.
You can easily replace them with a new endpoint from MapTiler. You just need to get an API key. You can start using the Free plan, which covers up to 100K requests monthly. Or adjust the code so user can use their API key in an env variable

You can also rewrite it to use proj4 to do the transformation: https://pyproj4.github.io/pyproj/stable/examples.html
