- Comparing responses across multiple providers
- Low-cost inference via open models (Llama 4, Mistral, DeepSeek)
- Vision tasks (Pixtral)
- Code generation (Codestral, Devstral)
- Reasoning tasks (Magistral)

## Payment Flow

### Option A — Spend Token (recommended for repeat use)
```bash
# 1. Top up at lightningprox.com/topup — pay Lightning invoice, get token
# 2. Use token directly
curl -X POST https://lightningprox.com/v1/messages \
  -H "Content-Type: application/json" \
  -H "X-Spend-Token: $LIGHTNINGPROX_SPEND_TOKEN" \
  -d '{
    "model": "claude-opus-4-5-20251101",
    "messages": [{"role": "user", "content": "Hello"}],
    "max_tokens": 1000
  }'
```

### Option B — Pay per request
```bash
# 1. Send request without token → get invoice
curl -X POST https://lightningprox.com/v1/messages \
  -H "Content-Type: application/json" \
  -d '{"model": "gemini-2.5-flash", "messages": [{"role": "user", "content": "Hello"}], "max_tokens": 100}'

# 2. Pay the Lightning invoice returned
# 3. Retry with X-Payment-Hash header
```

## Drop-in OpenAI SDK Replacement

```bash
npm install lightningprox-openai
```

```javascript
// Before: import OpenAI from 'openai'
import OpenAI from 'lightningprox-openai'
const client = new OpenAI({ apiKey: process.env.LIGHTNINGPROX_SPEND_TOKEN })

// Everything else stays identical:
const response = await client.chat.completions.create({
  model: 'claude-opus-4-5-20251101',
  messages: [{ role: 'user', content: 'Hello' }]
})
```

Two lines change. Nothing else does.
