Trusted by App Developers
"Search and pagination works flawlessly"
The tag search parameter and page pagination make infinite scroll lists very smooth. Highest recommendation for any mobile developer building visual apps.
"Best AMOLED category and super fast response"
The AMOLED wallpaper category alone is worth it. True pure-black wallpapers with crystal clear detail. My app users love the quality, and API response time stays under 40ms.
"Smooth React Native integration with WebP delivery"
The REST API is super clean and easy to use with React Native. Delivered WebP images save significant mobile data for our international users. Built a working MVP in 3 days!
Great work Priya! Fast WebP delivery was a top priority for mobile optimization.
"Zero downtime in 6 months of heavy usage"
Started on the free plan to test the API quality. The images were so good I upgraded to Pro the same day. Over 6 months in production and not a single outage.
"Commercial use allowed without hassle"
Many APIs restrict commercial apps or ask for exorbitant enterprise fees. NexWall allows commercial use on all tiers and makes scaling straightforward.
"Integrated in 20 minutes, 100% reliable"
Integrated NexWall API in under 20 minutes with Flutter http client. The 4K quality and edge CDN speed is unmatched for a free tier. My app went from 0 to 10K downloads in a month with zero image delivery lag.
Awesome to hear Arjun! Congrats on 10K downloads on WallZone 4K.
"Clean JSON structure & rapid CDN"
The category-wise JSON structure is exactly what I needed. Clean, fast, and the documentation is very clear. Upgraded to Pro after just one week to unlock all 50k+ wallpapers for my production users.
Thank you Riya! Glad the categorized endpoints made your Android architecture clean.
"The Live Wallpapers in Ultra plan are amazing"
Finally a wallpaper API built specifically for developers, not generic stock photos. The MP4 video live wallpapers in the Ultra plan are a massive game-changer for premium monetization.
