Demand index

The demand index is a weighted aggregation of classifier judgments about linked source items. It is not a measurement of token consumption, order flow, or provider utilization.

What it measures

A classified signal can carry direction, magnitude, confidence, category, mentioned models and providers, a rationale, and the source link. Magnitude and confidence are classifier outputs, not calibrated probabilities.

Unknown and neutral are distinct: unknown can mean no classification or an explicit unknown result; neutral means the item was classified without a directional view.

Signals and sources

Route	Purpose
GET /api/v1/signals	Filter and page source items and classifications
GET /api/v1/signals/sources	Read the configured public source list and current source status
GET /api/v1/signals/demand-index	Read index buckets and their components

Categories include capacity expansion, price change, funding, hiring, outage, model release, policy changes, and demand shifts. Clients should render the returned literal and source link rather than infer a category from the headline.

Index series

Index queries choose a window and interval. A request that would exceed the response bucket ceiling is rejected instead of silently dropping part of the series. The response carries component contributions so a client can distinguish a score with broad input from a score driven by a narrow subset.

The arithmetic is summarized on the Formulas page. Treat this feature as a news-derived signal and evaluate the underlying sources before acting on it.
