Get the Token Volume Index by day
The Token Volume Index: settled daily token volume for the closed frontier labs (anthropic, openai, google), with each lab indexed to 100 at its first settled day (growthIndex), its share of the closed-lab daily total (share), and the combined total indexed to 100 (totalGrowthIndex). The index is fixed-base: baselines anchor to each lab’s first settled day ever, not to the first day of the requested window, so overlapping windows return identical values for the same date. A lab absent for a day is left out of that day’s labs array rather than carried as a zero. Daily grain only. Requires an API key - like the Workload Cost Index there is no free tier.
Overview
The Token Volume Index: settled daily token volume for the closed frontier labs (anthropic, openai, google). Each lab carries its volume indexed to 100 at its first settled day (growthIndex) and its share of the closed-lab daily total (share); the combined total rides alongside as totalGrowthIndex. Both startDate and endDate are required - the series is read over an explicit window. The window selects which days come back; baselines stay anchored to each lab’s first settled day in the full history, so overlapping windows return identical values for the same date. A lab that settled no volume on a day is left out of that day’s labs array rather than reported as zero. Daily grain only. Requires an API key - like the Workload Cost Index, no part of this dataset has a free tier.Authorizations
