How this service works
List entities in an episode. Returns knowledge graph entities mentioned in a specific episode, with salience scores and occurrence counts.
Output
A list of knowledge graph entities detected in the specified episode, each annotated with a salience score (indicating how central/prominent the entity was) and an occurrence count (how many times it was mentioned). Response may be paginated via an opaque cursor for large entity sets.
Example use cases
Political figure tracking in news podcasts
“I'm monitoring coverage of Senator Warren across political podcasts — can you get me all the entities from episode 'ep-senate-hearing-0423' and tell me how prominently she appears based on salience scores?”
Topic research for episode summary
“I'm writing a brief on episode 'nyt-daily-20240601' — pull up the full list of knowledge graph entities mentioned in it so I can see what topics, people, and organizations are covered and how frequently.”
Comparing entity coverage across episodes
“For episode 'marketplace-morning-report-q1review', can you list all the entities with their occurrence counts? I want to see which companies and economic topics dominated the discussion.”
Technical details
Endpoint
GEThttps://api.particle.pro/v1/podcasts/episodes/:id/entitiesWhen to prefer
Use this endpoint when you need structured, scored entity data for a specific podcast episode — particularly useful for political intelligence, media monitoring, topic research, or building knowledge graphs from podcast content. Prefer this over general NLP APIs when you want pre-computed salience and occurrence data from Particle Pro's podcast index without running your own NER pipeline.
Side effects
- Episode ID not found — returns 404 if the slug or ID does not match any indexed episode
- Invalid cursor — pagination cursor is malformed or expired, returning an error
- Rate limiting or payment failure — x402 payment not accepted, returning 402 Payment Required
- Empty results — episode exists but has not been entity-analyzed yet
- Malformed limit parameter — non-integer or out-of-range value causes a 400 error
