Particle API extracts every sponsor read from every transcribed episode, attributes them to a company in the knowledge graph, and aggregates the result. You get sponsor-side analytics — who advertises where, how often, with what read style — without scraping audio yourself.
Available to MCP agents in the opt-in podcast_advertising category as particle_company_get_podcast_ad_presence, particle_podcast_get_sponsors, and particle_podcast_get_sponsor_leaderboard.

Per-company advertising

The fastest way to see how a single company shows up as a sponsor:

read_type_breakdown distinguishes host-reads from pre-recorded spots. placement_type distinguishes PRE_ROLL / MID_ROLL / POST_ROLL. recent_ads includes per-product attribution where the read called out a specific product line, plus segment timing within the episode — see Per-episode ads below for details.

A useful proxy for category fit — crypto-native sponsors dominate All-In, for example.

Per-episode ads

When you already have an episode in hand — for example, drilling in after list-episodes or after a transcript-based search — fetch the individual ad reads detected in that episode:

company resolves the sponsor read to a knowledge-graph company so you can join against company endpoints. Network promos (cross-promotion of other shows in the same network) are filtered out. For rolled-up views across episodes, see Per-podcast advertising summary and the Sponsor leaderboard below. Each ad carries the segment timing — start_seconds, end_seconds, duration_seconds — measured against the episode timeline. That’s enough to align ads with the transcript, measure read length, or join with the raw audio offset for downstream analysis. The most-active sponsors across the catalog:

Filter by metric (ad_count, podcast_reach, or episode_reach) to change the ranking dimension; by since / until to scope to a time window; or by company_id to constrain results to one sponsor’s brand family. Which sponsors run alongside each other on the same episodes — a useful signal for media-buying overlap, attribution analysis, or competitive positioning:
