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
