## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability rengi-forge-store-assets-generator-8751e0a3 -d '<json body>'
```

Example prompt: Take my key art (at least 1920px wide, no text) and my logo with transparent background and generate store images for itch.io, Google Play, Epic, and App Store — including the feature graphic, landscape and portrait Epic banners, and fitted screenshots from these three gameplay images.

## When to prefer this

Choose this endpoint when you need to batch-produce correctly sized store images across multiple platforms (itch.io, Google Play, Epic, App Store) from a single key art and logo — especially when you want alpha removed automatically for stores that reject it and screenshots fitted without stretching. Prefer over manual resizing or generic image tools when you need platform-exact pixel dimensions guaranteed.

## Known failure modes

- Key art smaller than 1920px wide may result in upscaled/blurry output
- Missing logo or key art when required fields are omitted
- Unsupported image format or corrupt base64 causes processing failure
- Screenshots with extreme aspect ratios may have significant letterboxing
- Payment failure via x402 returns 402 with no assets generated

## How this service works

Store assets: One key art and logo to the store images beyond Steam: itch.io cover 630x500, Google Play feature graphic 1024x500, Epic landscape 2560x1440 and portrait 1200x1600; gameplay screenshots fitted to Google Play 1920x1080 and App Store iPhone 6.9", 6.3" and iPad 13" sizes without stretching, no alpha where stores reject it.

## Output

Returns a set of platform-ready store images sized and composited to exact pixel dimensions for each requested store (itch.io, Google Play, Epic, App Store), with screenshots fitted without distortion and alpha stripped where stores reject it.
