Output
Returns a generated wallpaper image (likely as binary image data or a URL to the generated image) based on the provided theme string and optional integer seed for reproducibility.
Example use cases
Desktop background from text prompt
“Create me a wallpaper with a 'misty mountain forest at sunrise with golden light filtering through the trees' theme — use seed 7 so I can reproduce it later.”
Randomized daily wallpaper rotation
“Generate a new wallpaper with an 'abstract geometric patterns in deep ocean blues and purples' theme for today's desktop background.”
Branded themed wallpaper for team
“Make a wallpaper with the theme 'futuristic space station overlooking a ringed planet' using seed 100 so everyone on my team gets the exact same image.”

Endpoint
POSThttps://api.fastapi.online/generate-wallpaperWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.012 USDC), no-signup AI-generated wallpaper from a simple text theme, especially when reproducibility via seed is important. Prefer it over larger cloud image generators when cost per call matters, no account creation is desired, and the output is specifically sized/styled as a wallpaper.

- Invalid seed type (non-integer) — schema validation failure
- Payment failure via x402 protocol — 402 response requiring crypto payment
- Model inference timeout — service unavailable or slow response
- Missing required theme field — 422 Unprocessable Entity
