How this service works
List publishers for a sponsor. Returns the podcast publishers a sponsor advertises across, ordered by podcast coverage (the count of distinct publisher podcasts where the sponsor appears).
Output
A paginated list of podcast publishers where the specified sponsor has placed advertising, each entry including publisher details and the count of distinct podcasts within that publisher carrying the sponsor's ads, sorted descending by podcast coverage. Includes an opaque cursor for fetching subsequent pages.
Example use cases
Mapping a competitor's podcast reach
“Find every podcast publisher carrying Salesforce ads and rank them by how many of their shows feature Salesforce — use 'salesforce.com' as the identifier.”
Identifying top publisher partners for a brand
“Which podcast publishers does Squarespace advertise across the most? I want to see them ranked by podcast coverage so I can prioritize outreach.”
Auditing an advertiser's distribution footprint
“Pull the full list of podcast publishers running ads for the sponsor with ID 'sponsor_4821', and show me the first 20 results.”
Technical details
Endpoint
GEThttps://api.particle.pro/v1/podcasts/advertising/sponsors/:id/publishersWhen to prefer
Use this endpoint when you need to understand which podcast publisher networks a specific brand or sponsor buys advertising across, particularly when you want the coverage ranked by publisher breadth. Prefer this over the per-podcast sponsor list when the goal is publisher-level aggregation rather than episode-level detail. It is especially useful for competitive analysis, media planning, and publisher outreach prioritization.
Side effects
- Sponsor ID / company domain not found – 404 with no results returned
- Ambiguous identifier resolves to multiple companies – may aggregate unexpectedly across multiple sponsors
- Invalid cursor value causes pagination error
- Rate limiting or payment failure via x402 protocol returns 402 or 429
- Empty result if sponsor has no recorded podcast advertising
