PopNow effects and photo styles

PopNow's effects (https://popnow.ai/effects) are ready-made recipes: a model, a prompt written by PopNow and locked settings. The REST API has no separate effects endpoint, so this skill ships the recipes (references/effects.json, 143 effects) and scripts/effects.py, which applies one to the user's photo as an ordinary PopNow task on the underlying model: quote -> confirm -> create -> wait -> download. Python 3 standard library only. Paths below are relative to this skill's folder.

Rule: always confirm the price first

Effects spend the user's PopNow credits (1 credit = $0.001, so 1,000 credits = $1): about 125-340 credits for a 5-second effect video and 30-50 for an image style. Run quote, tell the user the 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

Steps

Find the effect. Names match loosely ("zombie" finds Zombie Turn):

python3 scripts/effects.py list --popular          # the trending ones
python3 scripts/effects.py list --search dance     # by keyword
python3 scripts/effects.py list --kind image       # photo styles only
python3 scripts/effects.py show "Tiny Planet"      # details, sample video, model

Or browse references/effects.md. If several match, show the user the options.

Quote with the user's photo (public HTTPS URL, popnow:// URI, or local JPEG/PNG/WebP, uploaded automatically for free):
```
python3 scripts/effects.py quote zombie-turn --image ./me.jpg
```
The output ends with the photo's popnow:// reference; pass that to create so the file is not uploaded twice.
Confirm the credits with the user.

Create and download (effect videos take about 1-3 minutes):

python3 scripts/effects.py create zombie-turn --image popnow://f/fil_... \
  --confirm-credits 336 --download ./popnow-output

Report the saved file and the credits charged. Without --download you get a taskId; finish with python3 scripts/popnow.py wait <taskId> --out ./popnow-output.

Tips

A clear, well-lit photo of one person (or one pet for pet effects) facing the camera works best.
The effect's prompt and settings are fixed. To change length, resolution or wording, use the popnow-video or popnow-image skill with the effect's model (show prints it) and your own prompt.
Two-person effects from the website are not available here because they need two photos placed in slots; point the user to https://popnow.ai/effects for those.
references/effects.json is a snapshot. New effects appear on the website first; update this skill to get them.

Errors

You see	Do
"matches several effects"	Pick one slug from the list, or ask the user
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
Task `failed` with `content_rejected` or `invalid_asset`	Refunded automatically; try a different, clearer photo

Alternative: MCP

With the PopNow MCP server connected (https://api.popnow.ai/mcp), the apply_effect tool runs the same effects by name.
