List episodes for a show, fetch a single episode, and create, update, and delete episodes straight from the command line or an existing CMS. Episode creation accepts an audio file upload (MP3 recommended, up to 150 MB). Endpoint paths are modeled from the documented resource operations - see the OpenAPI x-endpointsModeled note.

title: Acast Publishing API
description: >-
The Acast Publishing API lets you programmatically query data about your
shows and episodes, and create, update, and delete episodes straight from
the command line or an existing CMS. It also supports placing ad markers on
episodes for dynamic ad insertion. The API is documented openly at
developers.acast.com but is access-gated: you authenticate with an X-API-Key
header, and that key is issued by Acast's customer success team to accounts
on the Ace plan or in the Acast Creator Network. API keys are scoped to a
user and grant access only to the shows assigned to that user.
x-endpointsModeled: The resources, HTTP methods, base host, authentication
header, and rate limit below are confirmed from Acast's public
documentation (developers.acast.com and the Acast Learning Center). The exact
URL path templates and JSON schemas are MODELED as conventional REST paths
because Acast's full reference is served behind an interactive viewer that
requires credentials. Verify precise paths and payloads against the live
developer portal before relying on them in production.
