### Initialize Spanlens with CLI

Source: https://spanlens.io/docs

Use the CLI to automatically rewrite existing OpenAI, Anthropic, or Gemini calls in your codebase.

```bash
npx @spanlens/cli init
```

--------------------------------

### Initialize Spanlens with TypeScript

Source: https://spanlens.io/docs

Use the createOpenAI function to wrap OpenAI calls. It automatically reads the SPANLENS_API_KEY from the environment.

```typescript
import { createOpenAI } from '@spanlens/sdk/openai'

const openai = createOpenAI() // reads SPANLENS_API_KEY from env

const res = await openai.chat.completions.create({
  model: 'gpt-4o-mini',
  messages: [{ role: 'user', content: 'Hi' }],
})
```
