particle_podcast_list_related
List the shows most related to a podcast, best first — "shows like this show". Each result carries the related show's slug, a calibrated score in (0,1], and a coarse band (strong: same beat and audience; moderate: overlapping subject or audience; weak: a loose connection) to branch on. Add include: ["basis"] to see WHY each pair is related: content similarity of recent episodes, shared topics, shared guests (named), same publisher, shared sponsors — use it to explain a recommendation or to keep only pairs related for the reason you care about (shared guests for booking, content for media planning).
Related sets are precomputed per show from its transcripts, topic profile, guest roster, network and advertisers, restricted to the show's language. Only shows above a relatedness floor are listed, machine-generated and farmed feeds are never listed, and a publisher's duplicate feeds of one show appear once. An empty FIRST page is not an error: its coverage says whether the set is not computed yet, nothing cleared the floor, or the request's filters and the default policy removed everything; an empty page reached through a cursor is simply the end of the list.
Not a topic browser: for shows that COVER a topic use particle_podcast_resolve with topic_slug. Not a guest lookup: for where a person has appeared use particle_podcast_get_guest. Not advertiser co-occurrence: use particle_podcast_get_sponsors. Every related show's slug feeds particle_podcast_resolve, particle_podcast_list_episodes and the other podcast tools; person slugs in the basis feed particle_podcast_get_guest, topic slugs feed particle_podcast_resolve's topic_slug. For the five most related shows inline on a resolve, pass include: ["related"] to particle_podcast_resolve instead of calling this tool.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Results per page (1-50, default 10). | |
| cursor | No | Opaque pagination cursor from a previous response. | |
| include | No | Optional response sections. 'basis' attaches, per result, the signals that make the two shows related: content similarity of recent episodes, shared topics, shared guests (named), same publisher, shared sponsors. Off by default; opt in when you need to explain or filter by the reason. | |
| language | No | Only shows in this language: an ISO 639-1 code such as 'en' or 'es'. | |
| min_score | No | Drop results below this fused score (0-1]. Prefer branching on each result's band (strong / moderate / weak); score thresholds may be recalibrated as the ranker improves. | |
| podcast_slug | No | The source podcast — slug (e.g. 'all-in' from particle_podcast_resolve), internal ID, or numeric iTunes ID. A particle.pro or Radar show link also works. | |
| output_format | No | Output serialization. 'markdown' (default) returns the LLM-facing rendering. 'json' returns the structured payload as JSON text — use only for programmatic chaining where exact field extraction matters; the JSON shape is larger and noisier for an LLM to read. | |
| min_popularity | No | Only shows at or above this popularity percentile (0-1]. A floor above 0 excludes non-charting shows; 0 applies no floor. | |
| suitability_tier | No | Only shows whose latest brand-suitability tier is this value; never-assessed shows are excluded. | |
| publishing_status | No | Only shows that released an episode in the last 90 days ('active') or did not ('dormant'); shows with no known episode date match neither. | |
| exclude_same_publisher | No | Drop shows from the source show's own publisher. |
