Ask HN: Rentable cloud GPU provider with credit API?

I am looking for a provider that sells cloud GPU power and allows me to top up or even control my credit/balance via API.

I checked

- vast.ai - they don't have that - runpod.io - they don't have that - fly.io - they don't have that - pythonanywhere.com - didn't check it, people don't talk good - render.com - more a hoster not a CloudComputing provider - vercel - same same - paperspace - same same

Well, I could go for GCP I guess, but I want this flexible way of using remote GPU power like the three above offer them.

Also I could use AWS. While I have the experience there, I don't want to spent that much effort. The idea was to use e.g. render.com for hosting the web app and the question in service to do the computing.

If I could choose I'd take runpod.io, it seems easy to deploy machines. Did I oversee a service here? Is there anything out there that helps me achieve that?

Again: The only thing I am missing is: An API that allows me to see remaining credit and top it up.
