# Bifrost Gateway

Bifrost Gateway is a blazing-fast HTTP API that unifies access to 15+ AI providers (OpenAI, Anthropic, AWS Bedrock, Google Vertex, and more) through a single OpenAI-compatible interface. Deploy in seconds with zero configuration and get automatic fallbacks, semantic caching, tool calling, and enterprise-grade features.

## Quick Start

### Installation

Choose your preferred method:

#### NPX (Recommended)

```bash
# Install and run locally
npx -y @maximhq/bifrost

# Open web interface at http://localhost:8080
```

#### Docker

```bash
# Pull and run Bifrost Gateway
docker pull maximhq/bifrost
docker run -p 8080:8080 maximhq/bifrost

# For persistent configuration
docker run -p 8080:8080 -v $(pwd)/data:/app/data maximhq/bifrost
```

### Configuration

Bifrost starts with zero configuration needed. Configure providers through the **built-in web UI** at `http://localhost:8080` or via API:

```bash
# Add OpenAI provider via API
curl -X POST http://localhost:8080/api/providers \
  -H "Content-Type: application/json" \
  -d '{
    "provider": "openai",
    "keys": [{"value": "sk-your-openai-key", "models": ["gpt-4o-mini"], "weight": 1.0}]
  }'
```

For file-based configuration, create `config.json` in your app directory:

```json
{
  "providers": {
    "openai": {
      "keys": [{"value": "env.OPENAI_API_KEY", "models": ["gpt-4o-mini"], "weight": 1.0}]
    }
  }
}
```

### Your First API Call

```bash
curl -X POST http://localhost:8080/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-4o-mini",
    "messages": [{"role": "user", "content": "Hello, Bifrost!"}]
  }'
```

**That's it!** You now have a unified AI gateway running locally.
