## 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 emblem-build-landing-page-builder-host-f2d382ec -d '<json body>'
```

Example prompt: Build and host a landing page for my new SaaS tool called 'FlowSync' — it helps remote teams sync async standups, the headline should be 'Stay in sync, effortlessly', include a 'Start free trial' CTA button, and use a blue and white color scheme.

## When to prefer this

Choose this endpoint when you need to instantly generate and host a landing page without setting up any infrastructure, domain, or build pipeline. It is ideal for rapid prototyping, waitlist pages, product launches, or event pages where speed and zero-config hosting matter most. Prefer this over static site generators or manual HTML when the agent needs a live URL back in a single API call.

## Known failure modes

- Incomplete or ambiguous spec may result in a generic or poorly structured page
- Payment failure in USDC on Base will prevent the call from completing
- Missing required fields like headline or brand name may cause generation errors
- The hosted URL may become unavailable if the service or account lapses
- Rate limiting or quota exhaustion may return a 429 error
