PopNow music and speech

Make music, voiceovers and transcripts through the PopNow REST API (https://api.popnow.ai/api/v1). Every generation is a task: quote -> confirm -> create -> wait -> download, all handled by the bundled scripts/popnow.py (Python 3 standard library only). Paths below are relative to this skill's folder.

Rule: always confirm the price first

Generations spend the user's PopNow credits (1 credit = $0.001, so 1,000 credits = $1). Run quote, tell the user the credit price and balance, and only after a clear yes run create --confirm-credits <maxCredits>. The script re-quotes and will not start if the price went up (exit code 3, nothing charged). Failed tasks are refunded automatically.

Setup

export POPNOW_API_KEY="sk-popnow-..."   # https://popnow.ai/api/console/keys
python3 scripts/popnow.py balance

Music

python3 scripts/popnow.py quote --model suno/v6/text-to-audio \
  --prompt "Upbeat summer synth-pop about a road trip, female vocals, catchy chorus"
# "This song costs 72 credits. Go ahead?" -> on yes:
python3 scripts/popnow.py create --model suno/v6/text-to-audio \
  --prompt "Upbeat summer synth-pop about a road trip, female vocals, catchy chorus" \
  --confirm-credits 72 --download ./popnow-output

Useful Suno fields: --lyrics "..." (your own lyrics), --title "...", --set instrumental=true (no vocals), --set vocal_gender=female|male, --negative-prompt "...". A run can return more than one track; every file is downloaded. Songs take about 1-3 minutes.

Speech (voiceover)

python3 scripts/popnow.py quote --model google/gemini-3.8-flash-tts/text-to-speech \
  --text "Welcome to the show. Today we build a robot out of cardboard." --voice Kore

Gemini TTS voices include Kore (warm female, default), Puck (upbeat male), Charon (deep male), Aoede (bright female), Fenrir (excited male) and Leda (young female); add --set style=newscaster (also whisper, empathetic, vocal_smile, promo_hype, deadpan). Other speech models use different voice names and fields; check them with python3 scripts/popnow.py model <id> (free) before quoting. Speech is priced by length (per second of audio or per 1,000 characters).

Transcription and sound effects

Task	Model ID	Input
Speech to text	`xai/grok-stt/speech-to-text`	`--audio ./talk.mp3` (optional `--set language=en`)
Sound effects for a silent video	`popnow/foley-v1/video-to-audio`	`--video ./clip.mp4`, optional `--prompt`

--audio and --video accept a public HTTPS URL, a popnow:// URI or a local MP3/WAV/MP4/WebM file (uploaded automatically, free; up to 90 MiB and 600 seconds). Transcripts are printed and saved as <taskId>.txt.

Good defaults

Need	Model ID	Typical price
Song or instrumental	`suno/v6/text-to-audio`	about 72 credits
Alternative music model	`minimax/music-3.0/text-to-audio`	about 180 credits
Voiceover	`google/gemini-3.8-flash-tts/text-to-speech`	about 20 credits per minute of audio
Many languages / voice catalog	`minimax/speech-2.8-turbo/text-to-speech`	about 72 credits per 1,000 characters

Full list: references/models.md; live list: python3 scripts/popnow.py models --modality audio. Prices change; the quote is the exact number.

Content

Keep lyrics and scripts suitable for a general audience and do not imitate a real, named artist's voice. Declined requests fail with content_rejected and cost nothing.

Errors

You see	Do
Exit 3 price above the confirmed amount	Tell the user the new price; re-run only after they agree
`40201` not enough credits	Top up at https://popnow.ai/pricing
`400` naming a field	Fix it (check `model <id>`); nothing was charged
Task `failed` (exit 5)	Refunded automatically; read `errorCode` / `errorMessage`

Alternative: MCP

With the PopNow MCP server connected (https://api.popnow.ai/mcp), the tools create_music and create_speech do the same thing.
