Hostinger Horizons

Horizons is Hostinger's AI website builder. The API creates a website from a natural-language description and returns a link where the user can preview and edit it. Use it when a user asks to build a website, landing page, blog, or other web application, or to fetch an edit link for an existing Horizons site.

Core Concepts

Prompt-Driven Creation

You describe the desired site in natural language (the message), and Horizons generates it. The create call returns a website URL and ID immediately, but generation happens asynchronously — the site is built in the background after the call returns.

Messages

The create request takes a message array of message objects. Each has a type (currently text) and the text describing what to build, e.g. "Create a landing page for a coffee shop with a hero section, menu, and contact form."

Editing in the Horizons Interface

Horizons websites can only be modified inside the Horizons web interface. To change an existing site, fetch its edit link with GET /websites/{websiteId} and open the returned URL — there is no direct content-editing API.

Common Patterns

Create a Website from a Prompt

curl -X POST "https://developers.hostinger.com/api/horizons/v1/websites" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "message": [
      {
        "type": "text",
        "text": "Create a landing page for a coffee shop with a hero section, menu, and contact form"
      }
    ]
  }'

Returns a website URL and ID right away; the site continues generating asynchronously. Share the URL with the user to watch progress and preview the result.

Python SDK:

from hostinger_api import Hostinger

client = Hostinger(api_token="YOUR_API_TOKEN")

site = client.horizons.websites.create(
    message=[{"type": "text", "text": "Create a portfolio site for a photographer"}]
)
print(site.id, site.url)

TypeScript SDK:

import { Hostinger } from "hostinger-api-sdk";

const client = new Hostinger({ apiToken: "YOUR_API_TOKEN" });

const site = await client.horizons.websites.create({
  message: [{ type: "text", text: "Create a portfolio site for a photographer" }],
});
console.log(site.id, site.url);

PHP SDK:

use Hostinger\Api\HostingerApi;

$client = new HostingerApi('YOUR_API_TOKEN');

$site = $client->horizons->websites->create([
    'message' => [
        ['type' => 'text', 'text' => 'Create a portfolio site for a photographer'],
    ],
]);
echo $site->id . ' ' . $site->url . "\n";

Get an Edit Link for an Existing Website

curl -X GET "https://developers.hostinger.com/api/horizons/v1/websites/12345" \
  -H "Authorization: Bearer $HOSTINGER_API_TOKEN"

Returns a link to edit the website in the Horizons interface. Use this whenever the user wants to modify, edit, or add features to an existing Horizons site.

Best Practices

Prompts

• Be specific about sections, purpose, and tone in the message text — more detail yields a closer first result
• One clear description per create call; refine afterwards in the Horizons interface rather than re-creating

Async Handling

• Treat create as fire-and-forget: surface the returned URL to the user so they can watch generation finish
• Don't expect a fully built site in the create response — only the URL and ID are immediate

Editing

• Always fetch a fresh edit link via GET /websites/{websiteId} rather than caching old URLs

Troubleshooting

401 Unauthorized

• Verify your API token is valid and not expired
• Check the Authorization: Bearer <token> header format

422 Unprocessable Content

• The message array is missing or empty
• A message object is missing type or text

Website Not Ready

• Generation is asynchronous — give it time and revisit the returned URL
• The edit link from GET /websites/{websiteId} opens the site in the Horizons interface even while it finishes building
