## Common Workflows
### Create and List Notebooks
```bash
# 1. Create a notebook
NOTEBOOK=$(curl -s -X POST http://localhost:8000/api/v1/notebooks \
-H "X-API-Key: your-key" \
-H "Content-Type: application/json" \
-d '{"title": "AI Research"}' | jq -r '.data.id')
# 2. List all notebooks
curl http://localhost:8000/api/v1/notebooks \
-H "X-API-Key: your-key"
# 3. Get specific notebook
curl http://localhost:8000/api/v1/notebooks/$NOTEBOOK \
-H "X-API-Key: your-key"
```
### Update and Delete
```bash
NOTEBOOK_ID="550e8400-e29b-41d4-a716-446655440000"
# Update title
curl -X PATCH http://localhost:8000/api/v1/notebooks/$NOTEBOOK_ID \
-H "X-API-Key: your-key" \
-H "Content-Type: application/json" \
-d '{"title": "New Title"}'
# Delete notebook
curl -X DELETE http://localhost:8000/api/v1/notebooks/$NOTEBOOK_ID \
-H "X-API-Key: your-key"
```

## Error Codes
| Code | HTTP Status | Description |
|------|-------------|-------------|
| `VALIDATION_ERROR` | 400 | Input validation failed |
| `AUTH_ERROR` | 401 | Authentication failed (missing/invalid API key) |
| `NOT_FOUND` | 404 | Resource not found |
| `RATE_LIMITED` | 429 | Rate limit exceeded |
| `NOTEBOOKLM_ERROR` | 502 | External NotebookLM API error |
---
## Rate Limiting
API requests are rate-limited to prevent abuse. Rate limit headers are included in responses:
```http
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1712400000
```
If you exceed the rate limit, you'll receive a `429 Too Many Requests` response:
```json
{
"success": false,
"error": {
"code": "RATE_LIMITED",
"message": "Rate limit exceeded. Try again in 60 seconds.",
"details": [{"retry_after": 60}]
},
"meta": { ... }
}
```
