### Example .env configuration file

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

A template for the .env file used to configure service host, port, API keys, and model mappings.

```bash
AG2API_HOST=0.0.0.0
AG2API_PORT=3000
AG2API_API_KEYS=sk-your-secret-key-1,sk-your-secret-key-2
AG2API_PROXY_ENABLED=false
AG2API_PROXY_URL=
AG2API_DEBUG=false
AG2API_LOG_RETENTION_DAYS=3
AG2API_RETRY_DELAY_MS=1200
AG2API_QUOTA_REFRESH_S=300
AG2API_CLAUDE_MODEL_MAP={"claude-haiku-4-5":"gemini-3-flash","claude-haiku-4-5-20251001":"gemini-3-flash"}
AG2API_GEMINI_MODEL_MAP={"gemini-3-flash-preview":"gemini-3-flash"}
AG2API_MCP_XML_ENABLED=true
# Deprecated:
# AG2API_SWITCH_TO_MCP_MODEL=gemini-3-flash

```bash
npm run add
```

--------------------------------

### 手动启动容器

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

使用 docker run 手动启动容器并挂载数据卷。

```bash
docker run -d --name antigravity2api \
  -p 3000:3000 \
  --env-file .env \
  -v "$(pwd)/auths:/app/auths" \
  -v "$(pwd)/log:/app/log" \
  antigravity2api:latest
```

--------------------------------

### 本地构建与启动

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

使用 docker-compose 进行本地构建并启动服务。

```bash
docker compose up -d --build
```

--------------------------------

### 使用 GHCR 镜像启动与更新

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

使用 docker-compose 启动或更新 GHCR 镜像。

```bash
docker compose -f docker-compose.ghcr.yml up -d
```

```bash
docker compose -f docker-compose.ghcr.yml up -d --pull always
```

--------------------------------

### 复制环境变量文件

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

在部署前复制示例环境变量文件。

```bash
cp .env.example .env
```

--------------------------------

### Enable MCP XML Bridge via Environment Variable

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

Set this environment variable in your .env file to enable the MCP XML bridge.

```bash

### 手动构建镜像

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

手动构建 antigravity2api 镜像。

```bash
docker build -t antigravity2api:latest .
```

--------------------------------

### OpenCode 配置文件示例

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

位于 C:\Users\你的用户名\.config\opencode\opencode.json 的配置文件，用于指定 Anthropic 提供商的 baseURL。

```json
{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "anthropic": {
      "options": {
        "baseURL": "http://localhost:3000/v1"
      }
    }
  }
}
```

--------------------------------

### Claude Code 设置文件示例

Source: https://github.com/znlsl/antigravity2api/blob/main/README.md

参考 .claude/settings.json 的配置示例，用于定义默认模型和禁用非必要流量。

```json
{
  "ANTHROPIC_MODEL": "claude-opus-4-5-thinking",
  "ANTHROPIC_DEFAULT_HAIKU_MODEL": "gemini-3-flash",
  "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-5-thinking",
  "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-4-5-thinking",
