https://github.com/IRS-Public/direct-file <- Direct File's web app source code is public-domain and published on GitHub!

Obviously the 2025 version will be out of date for the 2026 filing season, though public code means it can always be revived by anyone else.

Does the "Modernized eFile API" still exist?

afaik yes, its what the for-profit companies like turbotax use as well. While its "modernized" in comparison to older systems it was originally created in 2004 (and you can tell because it has XML galore).
