Technical details
Endpoint
POSThttps://superdesigner.supercapital.fun/screen-spec?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, detailed UI screen specification generated from a natural-language description of a screen's purpose and data — particularly useful for product teams, AI coding agents needing design context, or design automation workflows. Prefer this over generic LLM prompting when you want design-intelligence-specific output framed around components, states, and design system conventions.
Side effects
- Empty or too-vague input string may produce generic or low-quality specs
- Input exceeding 8000 characters will be rejected with a validation error
- Payment failure or insufficient USDC balance will result in a 402 response
- Network or server errors may return a 5xx response with no output
