Стоимость сеанса по harness и модели

Возвращает агрегированные показатели стоимости сеанса для опубликованных harness, обновляемые еженедельно.
Сеансы никогда не объединяются между приложениями. Медианные значения рассчитываются на основе расходов в USD для отдельных сеансов, а агрегирование с сохранением конфиденциальности не раскрывает значения clerk_user_id или данные отдельных сеансов.
Фильтрация выполняется по app_slug, model или turn_range. Фильтрация только по model работает для всех приложений и позволяет сравнивать harness между собой при фиксированной модели. Результаты обновляются еженедельно и содержат в meta окно исходного снимка данных.

      summary: Cost per session by harness and model
      description: >-
        Returns weekly refreshed, aggregated cost-per-session cells for the
        published harnesses.

        Sessions are never pooled across apps. Medians are of per-session USD
        spend, and

        privacy-preserving aggregation never exposes clerk_user_id values or
        per-session rows.

        Filter by `app_slug`, `model`, or `turn_range`. Filtering by `model`
        alone works across apps

        for harness-vs-harness comparison at a fixed model. Results refresh
        weekly and include the source snapshot

        window in `meta`.
