|
## Claude Central Gateway - Implementation
|
|
|
|
**Why:** A lightweight proxy for Claude Code that routes requests to third-party API providers, deployable to Vercel without needing a VPS.
|
|
|
|
### Architecture
|
|
|
|
```
|
|
Claude Code → Gateway (Vercel) → OpenAI API
|
|
↓
|
|
Validate token
|
|
Transform request
|
|
Stream response
|
|
```
|
|
|
|
### Key Decisions
|
|
|
|
- **Language**: Node.js with JavaScript (no TypeScript)
|
|
- **Deployment**: Vercel serverless functions
|
|
- **Providers**: OpenAI first (via official SDK), others in TODO
|
|
- **Config**: Environment variables only (no database)
|
|
- **Auth**: Single shared token (user's `ANTHROPIC_AUTH_TOKEN` must match `GATEWAY_TOKEN`)
|
|
- **Streaming**: Full streaming support
|
|
- **Model mapping**: Via `MODEL_MAP` env var (format: `claude:openai,claude2:openai2`)
|
|
|
|
### Environment Variables
|
|
|
|
| Variable | Description |
|
|
|----------|-------------|
|
|
| `GATEWAY_TOKEN` | Shared token for authentication |
|
|
| `OPENAI_API_KEY` | OpenAI API key |
|
|
| `MODEL_MAP` | Model name mapping (optional) |
|
|
|
|
### File Structure
|
|
|
|
```
|
|
api/v1/messages.js - Main proxy handler
|
|
package.json - Dependencies (openai SDK)
|
|
vercel.json - Routing config
|
|
```
|
|
|
|
### How to apply: When adding new providers or modifying the gateway, follow the established pattern in `api/v1/messages.js` for request/response transformation.
