In the podcast_publishers category, which is opt-in — it is callable by name on any connection, but only advertised on tools/list when selected via ?include=podcast_publishers. See Tool sets & discovery.
A podcast publisher’s profile: name, slug, and catalog size. Request optional sections via include: podcasts for the publisher’s shows (podcast slugs feed the podcast tools), bias for the political-bias profile across the analyzed catalog (coverage, political share, lean, distributions), suitability for the IAB/GARM brand-suitability profile (tier breakdown, category exposure, top concerns). Publisher slugs come from podcast payloads and from the corpus-wide views: particle_podcast_get_bias_leaderboard, particle_podcast_list_bias_publishers, particle_podcast_get_suitability_leaderboard, and particle_podcast_list_suitability_category_publishers.
