How do I configure rate limiting?

AI Answer3 sources

To configure rate limiting, add the rateLimit option to your API configuration:

const config = {
  rateLimit: {
    requests: 100,
    window: '1m'
  }
}

This limits each API key to 100 requests per minute. You can also set per-endpoint limits.
