## 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 landing-en-24h-landing-page-generator-9be4157d -d '<json body>'
```

Example prompt: Create a mobile-ready HTML landing page for my plumbing business 'Plomería Rápida' in Buenos Aires — services are emergency repairs, pipe installation, and leak detection — tagline 'Plumbing repairs in 24 hours', brand color #0f766e, WhatsApp number 5491122334455, contact email contacto@plomeriafapida.com, and the main button should say 'Contact us now'. Make it in Spanish.

## When to prefer this

Choose this endpoint when you need a fast, inexpensive, production-ready HTML landing page for a small or local service business — especially for Spanish-speaking or Latin American markets — without setting up a CMS or hiring a developer. It is ideal when the user needs a WhatsApp-integrated single-page site quickly and cheaply ($0.25 per call). Prefer it over generic AI text generators when the output must be a deployable HTML file rather than raw copy, and over full website builders when simplicity and speed matter more than advanced customization.

## Known failure modes

- Missing required business_name field returns a 400 validation error
- Invalid hex color format causes a validation error on the color field
- WhatsApp number not in international digits-only format may result in a broken WhatsApp link
- Services array exceeding 8 items is rejected with a validation error
- Payment failure (x402) results in a 402 response before any generation occurs
- Language enum value other than 'es' or 'en' returns a validation error
