# Experiments (Deprecated)

> This endpoint is deprecated. Use /v1/studies instead.

<Warning>
  **Deprecated** — This endpoint will be removed after **July 1, 2026**. Use [`GET /v1/studies`](/api/studies) instead, which provides the same capacity and usage data with a cleaner response format.
</Warning>

## `GET /v1/experiments`

Returns project-level usage and per-experiment interview stats for all active experiments.

All responses include `Deprecation` and `Sunset` headers. See [`GET /v1/studies`](/api/studies) for the replacement.
