Overview

Daily index series for a public GPU. Without a key, the free tier covers 5 GPUs - H100 SXM, H200, B200, A100 SXM4, RTX 5090 - for the trailing 3 months (the same window charted for free on index.ornn.com); any other GPU (e.g. RTX PRO 6000 WS) requires a key. Pass your API key to unlock the full history back to the earliest available data. The response includes access: "public-3mo" | "full". Rate-limited per IP for anonymous callers.
