# OpenRouter Config Skill
## Description
This skill helps users configure and enable OpenRouter as the AI provider in Claude Code. It sets up the OpenRouter API key, configures the Anthropic-compatible API endpoints, and ensures Claude Code uses OpenRouter exclusively with proper failover capabilities.

### 1. Provider Failover for High Availability
Anthropic's API occasionally experiences outages or rate limiting. When you route Claude Code through OpenRouter, your requests automatically fail over between multiple Anthropic providers. If one provider is unavailable or rate-limited, OpenRouter seamlessly routes to another, keeping your coding sessions uninterrupted.
### 2. Organizational Budget Controls
### 2. Access to 100+ Models
OpenRouter gives you access to models from multiple providers including:
- **Anthropic**: Claude 3.5 Sonnet, Claude 3 Opus, Claude 3 Haiku
- **OpenAI**: GPT-4, GPT-4 Turbo, GPT-3.5
- **Google**: Gemini Pro, Gemini Flash
- **Meta**: Llama 2, Llama 3
- **Mistral**: Mixtral, Mistral Large
- **And many more**: xAI, Perplexity, Cohere, etc.
### 3. Organizational Budget Controls
For teams and organizations, OpenRouter provides centralized budget management. You can set spending limits, allocate credits across team members, and prevent unexpected cost overruns.
### 3. Usage Visibility and Analytics
### 4. Usage Visibility and Analytics
OpenRouter gives you complete visibility into how Claude Code is being used across your team. Track usage patterns, monitor costs in real-time, and understand which projects or team members are consuming the most resources. All of this data is available in your [OpenRouter Activity Dashboard](https://openrouter.ai/dashboard/activity).
## Usage
To use this skill, simply ask Claude Code to configure OpenRouter. The skill will:
1. Set up your OpenRouter API key
2. Configure the Anthropic-compatible environment variables
3. Ensure Claude Code uses OpenRouter exclusively
4. Set up proper provider priority (Anthropic 1P)
5. Verify the configuration is working
1. **Ask you which OpenRouter model you want to use**
2. Provide a link to browse available models
3. Guide you to copy the model name from OpenRouter's model catalog
4. Set up your OpenRouter API key
5. Configure Anthropic-compatible environment variables
6. Ensure Claude Code uses OpenRouter exclusively
7. Set up proper provider priority
8. Verify the configuration is working
## Prerequisites
- An OpenRouter API key (get one from https://openrouter.ai/keys)
- Claude Code installed
## Model Selection
### Step 1: Browse Available Models
Visit the OpenRouter models catalog to choose your preferred model:
- **OpenRouter Models**: https://openrouter.ai/models
### Step 2: Find and Copy Your Model
Browse through the available models and click on any model to see:
- Model name (click to copy)
- Pricing (input/output tokens)
- Context length
- Features (function calling, vision, etc.)
- Provider information
**Popular Model Examples:**
| Model | Provider | Best For |
|-------|----------|----------|
| `anthropic/claude-3.5-sonnet` | Anthropic | General coding, reasoning |
| `anthropic/claude-3.5-sonnet:beta` | Anthropic | Latest Claude features |
| `openai/gpt-4-turbo` | OpenAI | Fast, cost-effective |
| `google/gemini-pro-1.5` | Google | Long context |
| `meta-llama/llama-3.1-70b-instruct:free` | Meta | Free tier available |
| `mistralai/mistral-large` | Mistral | Multilingual |

### Model Selection
Choose your model from the OpenRouter model catalog:
- **Browse Models**: https://openrouter.ai/models
- Click on any model to see details and copy the model name
- Paste the model name when prompted by this skill
### Provider Priority
**Important**: Claude Code with OpenRouter is only guaranteed to work with the Anthropic first-party provider. For maximum compatibility, we recommend setting **Anthropic 1P** as the top priority provider when using Claude Code.
## Supported Models
When using Claude Code through OpenRouter, you can access Anthropic models including:
- Claude 3.5 Sonnet
- Claude 3 Opus
- Claude 3 Haiku
OpenRouter supports 100+ models from various providers. Browse the full catalog:
- **OpenRouter Models**: https://openrouter.ai/models
The specific model used depends on your Claude Code configuration and can be set via OpenRouter's model routing settings.
**Popular Anthropic Models:**
- `anthropic/claude-3.5-sonnet` - Latest, most capable
- `anthropic/claude-3-opus` - Best for complex tasks
- `anthropic/claude-3-haiku` - Fast, cost-effective
**Popular Alternative Models:**
- `openai/gpt-4-turbo` - GPT-4 with Turbo speed
- `google/gemini-pro-1.5` - Long context (up to 1M tokens)
- `meta-llama/llama-3.1-70b-instruct:free` - Free Llama 3 model

OpenRouter's "Anthropic Skin" behaves exactly like the Anthropic API. It handles model mapping and passes through advanced features like "Thinking" blocks and native tool use.
### Model Routing
When you specify a model name from the OpenRouter catalog, OpenRouter routes your request to the appropriate provider automatically, handling all API differences transparently.

**Privacy Note**: OpenRouter does not log your source code prompts unless you explicitly opt-in to prompt logging in your account settings. See their [Privacy Policy](https://openrouter.ai/privacy) for details.
## Changing Models
You can change your model at any time by:
### Option 1: Update Claude Code Settings
Edit `~/.claude/settings.json`:
```json

"provider": {
"baseUrl": "https://openrouter.ai/api",
"apiKey": "${ANTHROPIC_AUTH_TOKEN}",
"defaultModel": "new-model-name"

### Option 2: Use the Skill Again
Run the configuration process again and select a different model when prompted.
### Option 3: Per-Session Model Selection
In Claude Code, you can sometimes specify models inline:
```
/model openrouter:your-model-name

## Troubleshooting
### Model Not Found Errors
- Verify the model name is copied exactly from OpenRouter's model catalog
- Check that the model is currently available on OpenRouter
- Some models may have different naming conventions (e.g., with `:free`, `:beta` suffixes)
### Auth Errors
- Ensure `ANTHROPIC_API_KEY` is set to an empty string (`""`)
- If it is unset (null), Claude Code might fall back to its default behavior and try to authenticate with Anthropic servers
### Context Length Errors
- If you hit context limits, consider breaking your task into smaller chunks or starting a new session
- If you hit context limits, consider switching to a model with larger context window
- Break your task into smaller chunks or start a new session
- Check the model's context limit at https://openrouter.ai/models
