# 🌐 Public Gaia Domain

Each Gaia node provides a web-based chatbot UI and an OpenAI compatible web service.
Here are some popular nodes. Please refer to the [agent apps](../agent-integrations/intro) section to see how
to use the Gaia API in your favorite agent frameworks or apps.

Gaia nodes are organized into Gaia domains to provide public services. Each domain has a single API endpoint that load-balances across multiple nodes to ensure service availability. 

Below are some Gaia domains we offer developers for free. **However, you must apply for a developer account to access these domains**.
