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.
Example use cases
Indie game multi-store launch prep
“I'm launching my game on itch.io and Google Play next week. Can you use my key art and logo to generate the itch.io 630x500 cover and the Google Play 1024x500 feature graphic, and fit these five gameplay screenshots to Google Play 1920x1080 size without stretching or alpha?”
Epic Games Store listing images
“I need to submit my game to Epic and they want a landscape banner at 2560x1440 and a portrait one at 1200x1600. Can you generate both from my key art and overlay my logo correctly?”
Apple App Store screenshot sizing
“Apple keeps rejecting my screenshots because of the wrong dimensions. Can you take these gameplay screenshots and resize them to fit the iPhone 6.9", iPhone 6.3", and iPad 13" App Store sizes without stretching or leaving any alpha?”
Technical details
Endpoint
POSThttps://rengi.dev/v1/store-assets/stores?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
