Index API

The Index API is live. Headline TKX, Open, and Frontier are public. Request Access for the host, history, and keys.

The TKX is the independent index for what AI capability costs. Headline TKX, Open, and Frontier stay public on the live index — no key.

The Index API returns the live TKX and its history for your own internal analysis. Using TKX in pricing, contracts, routing or a product you offer customers needs a written license from Cambent.
