Thanks, Thomas, but that has only daily and monthly granularity for articles.
True. Sorry, replied too quickly. Hourly granularity is available for / metrics/pageviews/aggregate/{project}/{access}/{agent}/{granularity}/{start}/{end} https://wikimedia.org/api/rest_v1/#!/Pageviews_data/get_metrics_pageviews_aggregate_project_access_agent_granularity_start_end, but not what per-article, which is what you want. Pardon the spam.
