How this service works
List entities. List knowledge graph entities (people, organizations, places) across all podcast content.
Output
A paginated list of knowledge graph entity records extracted from podcast content. Each entity includes its slug, type (e.g. person, company, place), and associated metadata. When using bulk IDs lookup, returns exactly the matched entities. Unresolved slugs or IDs are silently omitted. Response includes an opaque cursor for pagination.
Example use cases
Podcast guest research pipeline
“List all people entities mentioned in the Lex Fridman podcast so I can build a guest appearance tracker — give me up to 100 results.”
Brand mention monitoring across podcasts
“Find all company entities that appear in the All In podcast using Particle Pro's knowledge graph so I can see which organizations get discussed there.”
Bulk entity detail lookup
“I have a list of entity slugs — 'sam-altman', 'apple', 'openai', 'elon-musk' — can you bulk fetch their details from Particle Pro's entity database?”
Technical details
Endpoint
GEThttps://api.particle.pro/v1/entitiesWhen to prefer
Use this endpoint when you need to enumerate or filter knowledge graph entities (people, organizations, places) extracted from podcast audio content at scale — especially when you want to filter by entity type or scope to a specific podcast. Prefer this over a general web search when you need structured, podcast-specific entity data with pagination and bulk lookup support. This is the right choice when building entity-level analytics, guest trackers, or brand-mention monitors grounded in podcast content.
Side effects
- Invalid entity type slug returns empty results or error — must match slugs from GET /v1/entities/types
- Unresolvable entity slugs in bulk ID lookup are silently omitted rather than errored
- Pagination cursor from a different query may produce unexpected results
- podcast_id that doesn't match any known podcast slug or ID returns empty list
- Exceeding max 100 IDs in bulk lookup may result in truncation or error
- Rate limits or payment failures (x402) may block access
