# OpenRouter Config Skill
Helps users configure and enable OpenRouter as the AI provider for Claude Code by setting up the OpenRouter API key, configuring Anthropic-compatible environment variables, and ensuring proper provider priority and failover capabilities.
Helps users configure and enable OpenRouter as the AI provider for Claude Code by letting them select their preferred model from the OpenRouter catalog, setting up the API key, configuring Anthropic-compatible environment variables, and ensuring proper provider priority and failover capabilities.
## Documentation Source
Official OpenRouter Claude Code Integration Guide: https://openrouter.ai/docs/guides/claude-code-integration
## What It Does
1. **API Key Setup**: Securely configures the OpenRouter API key
2. **Environment Configuration**: Sets up Anthropic-compatible environment variables
3. **Provider Priority**: Ensures Anthropic 1P is set as top priority provider
4. **API Endpoint Configuration**: Configures `https://openrouter.ai/api` as the base URL
5. **Configuration Verification**: Validates that the configuration is working correctly
6. **Failover Setup**: Enables automatic provider failover for high availability
1. **Model Selection**: Prompts user to choose a model from OpenRouter's 100+ model catalog
2. **Model Catalog Guidance**: Provides link to https://openrouter.ai/models and instructions to copy model name
3. **API Key Setup**: Securely configures OpenRouter API key
4. **Environment Configuration**: Sets up Anthropic-compatible environment variables
5. **Model Configuration**: Stores chosen model in Claude Code settings
6. **Provider Priority**: Ensures Anthropic 1P is set as top priority provider
7. **API Endpoint Configuration**: Configures `https://openrouter.ai/api` as the base URL
8. **Configuration Verification**: Validates that the configuration is working correctly
9. **Failover Setup**: Enables automatic provider failover for high availability
## Key Benefits
### 1. Provider Failover for High Availability
Anthropic's API occasionally experiences outages or rate limiting. OpenRouter automatically fails over between multiple Anthropic providers, keeping coding sessions uninterrupted.
### 2. Organizational Budget Controls
### 2. Access to 100+ Models
Choose from models by Anthropic, OpenAI, Google, Meta, Mistral, xAI, and many more providers. Browse the complete catalog at https://openrouter.ai/models
### 3. Organizational Budget Controls
Centralized budget management with spending limits, credit allocation, and cost overrun prevention for teams.
### 3. Usage Visibility and Analytics
### 4. Usage Visibility and Analytics
Complete visibility into Claude Code usage across teams, including usage patterns, real-time cost monitoring, and resource consumption tracking via the [OpenRouter Activity Dashboard](https://openrouter.ai/dashboard/activity).
## Model Selection Process
### Step 1: Ask for Model Preference
When the skill starts, it will ask:
> "Which OpenRouter model would you like to use with Claude Code?"
### Step 2: Provide Model Catalog
The skill will provide a link to browse available models:
- **OpenRouter Models**: https://openrouter.ai/models
### Step 3: Guide User Selection
The skill will instruct the user to:
1. Visit https://openrouter.ai/models
2. Browse through the available models
3. Click on a model to see details (pricing, context length, features)
4. Copy the model name (click the model name to copy it)
5. Paste the model name back into the chat
### Step 4: Store Model Configuration
The skill will configure the chosen model in Claude Code settings at `~/.claude/settings.json`:
```json
{
"provider": {
"baseUrl": "https://openrouter.ai/api",
"apiKey": "${ANTHROPIC_AUTH_TOKEN}",
"defaultModel": "user-selected-model-name"
}
}
```

### Model Name Accuracy
Model names must be copied exactly from OpenRouter's model catalog (https://openrouter.ai/models). Include any suffixes like `:free`, `:beta`, etc.

## Troubleshooting
### Model Not Found Errors
- Verify the model name is copied exactly from OpenRouter's model catalog
- Check that the model is currently available
- Some models may have different naming conventions (e.g., with `:free`, `:beta` suffixes)
- Check https://openrouter.ai/models for current availability
### Auth Errors
- Ensure `ANTHROPIC_API_KEY` is set to empty string (`""`)
- Check that environment variables are set in shell profile (not just current session)
- Restart terminal after updating shell profile
### Context Length Errors
- Switch to a model with larger context window
- Check model context limits at https://openrouter.ai/models
- Break tasks into smaller chunks
