Gateway Overview

Encore is a unified AI gateway that provides a single access layer for Claude, Codex, Gemini, and other model providers. It gives you one authentication pattern, one base URL structure, and predictable routing rules.

What You Can Do With the Gateway

Manage access to different model providers through one gateway
Use one API key pattern across clients and SDKs
Connect through compatible clients and SDKs quickly
Switch between Claude, Codex, Gemini, and other capabilities under one setup

What You Need Before Integration

Before sending requests, prepare the following:

A valid API key
The correct client or SDK configuration entry
The target model or client type you plan to use

Base URL

Standard gateway base URL:

https://api.stillhappy.cn

Antigravity base URL:

https://api.stillhappy.cn/antigravity

Authentication

Encore uses Bearer Token authentication:

Authorization: Bearer YOUR_API_KEY

Routing and Endpoints

Please distinguish between the following:

Base URL: what you configure in an SDK or compatible client
Endpoint: the full HTTP address used when sending direct requests

Scenario A: Using an official SDK or compatible client

In this case, you usually only need the base URL.

Standard gateway: https://api.stillhappy.cn
Antigravity gateway: https://api.stillhappy.cn/antigravity

Scenario B: Sending raw HTTP requests

When using curl or a custom HTTP client, use the full endpoint.
