A first-party host for the Index API is opening next. Until then, read the live index and request access — we'll notify you.
The TKX is the independent index for what AI capability costs. Headline TKX, Open, and Frontier stay public on the live index — no key. API access, history, and a first-party host are next.
When the host is public, you will read positioning data you can cite, price against, or feed into your own routing. Cambent publishes the signal; your stack makes the choice.
