Overview

The Workload Cost Index: daily settled cents per request, a mix-purged like-for-like index, and tokens per request for each closed-lab provider (anthropic, openai, google). With no startDate or endDate this returns the entire settled history for every provider and model family, so pass a range unless you actually want the full series - the unfiltered payload grows with every settlement day. Use lab to filter to a single provider. Requires an API key - unlike the GPU and token indices, the Workload Cost Index has no free tier.
