cast0: Turn Text into a Published Podcast

Give your AI a voice. This plugin lets OpenClaw agents create podcast episodes via cast0. One tool call: text in, episode in your feed.

Your AI writes a briefing. You listen to it on your commute. No reading required.

Install

openclaw plugins install clawhub:@cast0/openclaw-plugin-cast0

Then configure your API key (get one at cast0.ai):

openclaw plugins config cast0 set apiKey pk_xxxxx
openclaw gateway restart

Tools

create_episode

Creates a podcast episode from text. The text is read verbatim by TTS: your AI writes the script, cast0 reads it. Returns immediately with a queued episode id.

Response: { id, status: "queued" }

Episodes auto-publish to your RSS feed when processing completes. Subscribe once in Apple Podcasts, Spotify, or any podcast app — episodes appear automatically.

get_episode

Fetches the current state of an episode. Poll until status is done to get the audio URL.

Response: { id, title, status, audioUrl? }

Status values: queued, processing, done, failed.

list_episodes

Lists all episodes for this podcast, newest first.

No parameters.

Response: array of { id, title, status, audioUrl? }

Example agent prompt

Summarize today's Hacker News top 10 and publish it as a cast0 episode titled "HN Digest".
Poll until the episode is done, then tell me the audio URL.
