I want to migrate my existing AI API code to use Keymesh. Keymesh is a proxy that lets me use virtual API keys with budget limits and usage tracking.

Here's what I need you to do:
1. Update my base URL to https://proxy.keymesh.dev/v1 (for OpenAI) or https://proxy.keymesh.dev (for Anthropic)
2. Replace my API key with my Keymesh virtual key (format: km_live_...)
3. Keep everything else the same - Keymesh is a transparent proxy

## HTTP Requests (curl, fetch, axios)

cURL:
```bash
curl https://proxy.keymesh.dev/v1/chat/completions \
  -H "Authorization: Bearer km_live_your_key" \
  -H "Content-Type: application/json" \
  -d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "Hello!"}]}'
```

JavaScript fetch:
```javascript
const response = await fetch('https://proxy.keymesh.dev/v1/chat/completions', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer km_live_your_key',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ model: 'gpt-4o', messages: [...] }),
});
```

Axios:
```javascript
const response = await axios.post('https://proxy.keymesh.dev/v1/chat/completions', 
  { model: 'gpt-4o', messages: [...] },
  { headers: { 'Authorization': 'Bearer km_live_your_key' } }
);
```

## SDK Examples

OpenAI Python:
```python
client = OpenAI(api_key="km_live_your_key", base_url="https://proxy.keymesh.dev/v1")
```

OpenAI TypeScript:
```typescript
const client = new OpenAI({ apiKey: "km_live_your_key", baseURL: "https://proxy.keymesh.dev/v1" });
```

Anthropic Python:
```python
client = anthropic.Anthropic(api_key="km_live_your_key", base_url="https://proxy.keymesh.dev")
```

## Key Points
- OpenAI endpoints: https://proxy.keymesh.dev/v1/...
- Anthropic endpoints: https://proxy.keymesh.dev/v1/messages (no /v1 prefix for SDK)
- All keys start with: km_live_
- Streaming works the same way

Please analyze my code and show me exactly what changes I need to make to migrate to Keymesh.
