## 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 url-design-tokens-extractor-2b24e4ef -d '<json body>'
```

Example prompt: Can you extract the design tokens — colors, fonts, spacing — from https://www.stripe.com so I can replicate their visual style?

## When to prefer this

Choose this endpoint when you need to programmatically extract design tokens from a live website URL, especially when you want to reverse-engineer a design system, audit brand consistency, or replicate visual styles from an existing site. It is particularly useful for front-end developers and designers who need structured token data rather than manual inspection via browser DevTools.

## Known failure modes

- URL is not HTTPS — the schema requires https:// prefix, so http:// URLs will be rejected
- Target URL is unreachable or returns a non-200 status — extraction fails with no tokens returned
- Page is heavily JavaScript-rendered and tokens cannot be statically extracted
- Empty response example suggests output schema may be sparse or inconsistent
- Payment failure via x402 protocol results in 402 error before processing begins
- URL points to a PDF or non-HTML resource with no extractable design tokens

## How this service works

## Output
