Sora Videos API jobs complete, but MP4 download fails with 403 Files are not accessible.

I think _j’s test is useful because it shows the content endpoint can work for at least some accounts/jobs.

I also tested this and was able to retrieve/download completed video content successfully.

So this may not be a general Videos API outage. It could be specific to your account/org/project, the generated file attached to that job or a backend file-access issue affecting some outputs.

Since you already tested several request variants and even different org/key combinations. I’d probably send this to the Help Center if it keeps happening, with the job IDs, timestamps, request/error bodies and mention that other users were able to retrieve completed video content successfully.
