How this service works
List appearances for a podcast guest. Returns the chronological list of episodes a guest has appeared on, most recent first.
Output
A paginated list of podcast episode appearance records for the specified guest, ordered most-recent-first. Each record includes episode and podcast identifiers, publication date, speaking time in seconds, and the podcast's brand-safety suitability tier. A pagination cursor is returned when more results are available.
Example use cases
Guest research for podcast booking
“I'm considering booking Sam Altman for our podcast — can you pull his full appearance history from Particle Pro using his person slug 'sam-altman' so I can see which shows he's been on and how recently?”
Topic-filtered guest episode discovery
“Find all episodes where Andrew Huberman has appeared that are classified under the 'health' topic — use his slug 'andrew-huberman' and restrict to episodes published after 2023-01-01.”
Brand-safe advertiser guest vetting
“I need to vet a potential sponsorship guest — pull the podcast appearances for person slug 'joe-rogan' but only show me episodes on podcasts rated SAFE or LIMITED for brand safety, with at least 600 seconds of speaking time.”
Technical details
Endpoint
GEThttps://api.particle.pro/v1/podcasts/guests/:id/appearancesWhen to prefer
Use this endpoint when you need structured, filterable episode-level appearance data for a specific podcast guest — especially when you need brand-safety filtering, topic scoping, or minimum speaking time thresholds. Prefer this over general podcast search when you already know the guest's identity and want their chronological appearance history across all podcasts in the Particle Pro index.
Side effects
- Unknown guest ID returns 404 not found
- Invalid suitability_tier_max enum value returns 400 bad request

- No appearances matching filters returns empty results list
- Expired or invalid pagination cursor returns 400 or empty results
