Packs

Download an asset file

The asset's own bytes, with the matching content type: PNG for textures and icons, JSON for models, Ogg Vorbis for sounds.

Remember the prefixed names: texture/item:rusted_key, texture/gui:shop_menu, texture/hud:frostbite.

Asking before it's ready answers 409 rather than handing back the placeholder that sits there while it generates — a blank PNG that looked like a result is the one genuinely misleading answer available here.
