# Quickstart

### Welcome to Cros 🌐

Cros is a web intelligence platform designed to help AI agents navigate and interact with the internet efficiently. By transforming websites into structured, machine-readable environments, Cros enables seamless automation, data extraction, and intelligent browsing.

### Get an API Key

To get started, connect a wallet on our home page at [Cros](https://cros.one/) and request a free API key. We offer a free tier for testing, with a pay-as-you-go model for production use. For details on authentication and error handling, visit the Authentication page.

### Available Endpoints

With your API key, you can integrate Cros into your applications using our REST API. The API provides three core endpoints:

* **POST /observe** – Analyzes a website and extracts its structure and available actions.
* **POST /step** – Executes an action on a previously observed website.
* **POST /scrape** – Extracts structured data from a given website.

For detailed documentation on these endpoints, refer to the API Documentation.
