How this service works
List sponsors for a publisher. Returns a paginated list of sponsors active across the publisher's catalog.
Output
A paginated JSON list of sponsor/company records active on the publisher's podcast catalog, each including company identifiers, ad counts, podcast coverage (number of distinct shows), and episode reach metrics. Includes an opaque cursor for fetching the next page.
Example use cases
Competitive ad intelligence for podcast network
“Who are the top advertisers on the NPR podcast network right now? Sort them by how many podcasts they're covering and only show me brands appearing on at least 5 shows.”
Brand safety audit for publisher partnership
“I'm evaluating a partnership with BBC Radio 4 — can you pull the full list of sponsors active on their podcast catalog so I can check if any competitors are already advertising there?”
Sales prospecting for podcast ad inventory
“List the sponsors on the Wondery publisher catalog sorted by ad count — I want to see who's buying the most ad slots so I can identify which brands are heavily investing in that network.”
Technical details
Endpoint
GEThttps://api.particle.pro/v1/podcasts/publishers/:id/advertising/sponsorsWhen to prefer
Use this endpoint when you need to discover which advertisers are sponsoring content across an entire podcast publisher's catalog — especially for network-level buyer analysis, competitive intelligence, or sales prospecting. Prefer this over the company-level endpoint when the starting point is a publisher/network rather than a specific brand, and when you need cross-show sponsor coverage metrics.
Side effects
- Unknown publisher slug or ID returns a 404 not found error
- Invalid sort enum value returns a 400 bad request
- Invalid min_podcast_coverage value (non-integer) returns a 400 validation error
- Expired or malformed pagination cursor returns an error or empty results
- Payment not processed (x402 protocol) results in a 402 Payment Required response
- Publisher with no active sponsors returns an empty list
