## 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 control-freelance-schema-kit-61ef6055 -d '<json body>'
```

Example prompt: Generate Schema.org structured data for my freelance web design service called 'PixelCraft Studio' — I charge 150 USD, my email is hello@pixelcraft.io, I'm based in Buenos Aires, and the description is 'Custom web design and branding for small businesses.'

## When to prefer this

Choose this endpoint when you need to generate Schema.org JSON-LD structured data for a freelance or professional service listing — especially when the output needs to be directly embeddable as an HTML script tag. Prefer this over generic schema generators when the use case is specifically a freelance/service business context with pricing, contact info, and geographic coverage.

## Known failure modes

- Missing required fields (name, description) returns a validation error
- Invalid email format causes a 400 bad request
- Price string not matching numeric pattern causes rejection
- Description shorter than 10 characters or longer than 500 characters fails validation
- Invalid currency code (not 3 uppercase letters) returns an error
