  title: Transistor Account Analytics API
  description: The Transistor API is a public REST API for the Transistor podcast hosting and analytics platform. It follows the JSON:API specification, accepts JSON or form-encoded request bodies, and returns JSON:API resource objects. It supports sparse fieldsets and included related resources. Authentication is via an x-api-key header carrying an API key generated in the Transistor dashboard Account area. The API covers shows, episodes, download analytics, private podcast subscribers, and event webhooks. Requests are rate-limited to 10 requests per 10 seconds; exceeding the limit returns HTTP 429 and blocks access for 10 seconds.
