Can you get a temporary one that is revocable later? (Not an OpenAI user myself, but that would seem to be a way to lower the risk to acceptable levels)

You can generate and revoke them easily, so I don't quite get the issues. Create one, use the tool, revoke, done.

You can create named API keys, and easily delete them. Unfortunately you can't seem to put spend limits on specific API keys.

If you're not using the API for serious stuff though it's not a big problem, as they moved to pre-paid billing recently. Mine was sitting on $0, so I just put in a few bucks to use with this site.
