# API Reference

> A comprehensive API reference to help developers quickly integrate and use AI API endpoints.

## Get started

Poixe AI is compatible with multiple mainstream protocols and provides a unified API entry point: all you need is a `base_url` and an `api_key`. Replace the address and key in your existing code with them to complete the integration.
