How this service works
List trending sponsors. Surfaces advertisers whose podcast ad volume is accelerating.
Output
A paginated list of advertisers (sponsors) ranked by the acceleration of their podcast ad volume — comparing ad placements in the most recent window_days period against the equally-sized prior period. Each record surfaces the sponsor identity and trend signal. A pagination cursor is included for fetching subsequent pages.
Example use cases
Competitor ad spend monitoring
“Which brands in the B2B SaaS space are ramping up their podcast advertising? Use a 14-day window and make sure they're advertising on at least 3 distinct shows so I know it's a real trend, not one show binge-publishing.”
Sales prospecting for podcast networks
“I'm trying to find brands that are accelerating their podcast ad buys so I can pitch them new inventory — pull the top 25 trending sponsors over the last 30 days, filtering to those active across at least 10 different podcasts.”
Investment signal research
“I want to see which companies are suddenly pouring money into podcast advertising over the past 7 days compared to the 7 days before that — give me the top 10 trending sponsors as a growth signal for market research.”
Technical details
Endpoint
GEThttps://api.particle.pro/v1/podcasts/advertising/sponsors/trendsWhen to prefer
Use this endpoint when you need a ranked, time-windowed view of which advertisers are growing their podcast presence — not just who advertises, but who is accelerating. Prefer this over the company advertising profile endpoint when you don't have a specific company in mind and want to discover emerging sponsors. The min_podcast_reach filter makes it robust against single-show spikes, making it reliable for competitive intelligence and sales prospecting.
Side effects
- Invalid window_days value (e.g. zero or negative) returns a 400 error
- Cursor from a different query context may return a 400 or empty results
- min_podcast_reach set too high may return an empty result set with no error
- Rate limiting or payment failure (402) if USDC balance is insufficient
- Transient 500 errors if upstream podcast data pipeline is delayed
