Example use cases
Branded wallpaper pattern for app
“Create a repeating pattern with the theme 'circuit board tech' using seed 7 — I want something I can use as a background in my developer dashboard.”

Reproducible pattern for game asset

Technical details
Endpoint
POSThttps://api.fastapi.online/generate-pattern?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, novelty or decorative pattern generated from a plain-text theme description, especially when reproducibility via a seed is important, and you want to pay per call without a subscription or signup. Prefer it for lightweight creative or developer tooling tasks rather than full image generation.
Side effects
- Theme string too short or too long (violates minLength 1 / maxLength 300 constraint)
- Seed value out of integer range
- Payment not included or insufficient (HTTP 402 returned)
- Model unavailable or server error (HTTP 500)
- Empty or nonsensical theme producing low-quality or undefined output
