List the GPU Availability Index

How often each GPU could actually be rented: one frozen row per GPU model per completed UTC day, computed from FastGPU's recorded stock history (each provider's own stock tier or rentable host count, on-demand and community offers only) and never revised. Each row gives the providers listing the GPU, the providers that exposed a stock signal, the providers that had it rentable at least once that day, the signalled and rentable stock checks, the rentable share (rentable / signalled; offers without a signal never count as in stock or sold out) and the marketplace host depth. Newest day first. The method is published at /gpu-availability#method. No key required.
