## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability superdesigner-screen-spec-generator-5aee48e9 -d '<json body>'
```

Example prompt: Can you generate a full screen spec for a mobile order-tracking screen that shows real-time delivery status, estimated arrival time, driver location on a map, and lets users contact support or cancel the order?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Product design intelligence. Critiques, systems and specs for interfaces that work.

## Output

Returns a structured JSON object containing a jobId, a detailed screen specification text covering layout hierarchy, component breakdown, interaction states, data requirements, and design system guidance, plus a payment receipt with transaction hash, amount, and network.
