The badge shows the median Vast.ai asking price this hour. GPUs not on the marketplace show the lowest published rate card, marked “from”. Images refresh about every 15 minutes.

API reference

Base URL https://gridcompute.ai. All endpoints are GET. Prices are in USD per GPU-hour, asking prices, not offers. Timestamps are Unix seconds at the start of the UTC hour. Missing values are null, never estimated.

Data updates once an hour, a few minutes past the hour, and responses are cached for 5 minutes. There is no hard rate limit; please cache on your side rather than polling more than hourly. New fields may be added; existing fields will not be renamed or removed without notice on this page.

Market prices come from public Vast.ai listings. Rate cards: RunPod (Secure Cloud on-demand), Verda (on-demand, 1-GPU instance), Azure (pay-as-you-go Linux VM, East US 2, per GPU). Full method on the homepage.
