## Configuration (Optional)

The defaults work well for most users. All settings can be adjusted via environment variables:

| Variable | Description | Default |
|----------|-------------|---------|
| `UW_API_KEY` | Your Unusual Whales API key | Required |
| `UW_RATE_LIMIT_PER_MINUTE` | Max requests per minute | `120` |
| `UW_MAX_RETRIES` | Retry attempts for failed requests | `3` |
| `UW_CIRCUIT_BREAKER_THRESHOLD` | Failures before pausing requests | `5` |
| `UW_CIRCUIT_BREAKER_RESET_TIMEOUT` | Milliseconds before retrying after failures | `30000` |

The server automatically handles rate limiting, retries failed requests with backoff, and temporarily pauses requests if the API is having issues (circuit breaker). See [CONTRIBUTING.md](CONTRIBUTING.md) for technical details.
