How it works
Two ways to make a demo.
Same render core, two on-ramps. The script lives in your dashboard either way; every render lands in your renders overview.

Subscribe. Mint a key. Render from anywhere.
- 1Subscribe and create a
cb_live_…API key. - 2Hand the key + our agent skill bundle to Claude (or your own agent).
- 3Agent authors against the JSON Schema, POSTs to
/v1/renders, MP4 lands in storage.
