Tunova bills **only on success** \u2014 a failed track auto-refunds to your balance, the rest of the playlist still arrives. Re-run for stragglers, you never pay twice.\n\n### Setup (3 min)\n1. Grab a key at [tunova.ai](https://tunova.ai) \u2014 **50 free tokens, no card** (\u22485 songs; each track costs 10).\n2. Create a **Header Auth** credential: name `X-API-Key`, value `sk_live_\u2026` \u2014 select it in both Tunova nodes.\n3. Create a **Telegram** credential (bot token from @BotFather) and put your chat id into *Playlist config*.\n4. Set *tracks* to your playlist size (default 3 fits the free tier).",
