Easy-to-use PHP library implementing the IndexNow protocol that allows websites to notify search engines whenever content on any URL is updated or created, enabling instant crawling and discovery.

🎯 Key Features
--------------

[](#-key-features)

- **Instant indexing** - Notify search engines immediately when your content changes
- **Multi-engine support** - Built-in support for Bing and Yandex, with ability to add custom endpoints
- **Simple API** - Single method call to ping search engines about URL changes
- **Lightweight** - Zero external dependencies, uses native PHP cURL
- **PHP 8.0+** - Modern PHP with strict typing and clean architecture

🔍 How It Works
--------------

[](#-how-it-works)

The IndexNow protocol is a simple ping mechanism that informs search engines about recent changes to your website content:

1. **Generate API Key** - Create a unique API key and host it as a text file at your domain root
2. **Initialize Service** - Create an `IndexNow` instance with your API key and target search engine
3. **Send Notifications** - Call `sendChangedUrl()` whenever you update or create content
4. **Search Engine Crawls** - The search engine receives the ping and prioritizes crawling your URL
