## Rate Limits
By default, you can make up to 10,000 calls per day to all API endpoints, including authorization. Monitor your daily quota and the remaining number of API calls by inspecting the HTTP headers ```X-RateLimit-Limit``` and ```X-RateLimit-Remaining``` in each response. The ```X-RateLimit-Retry-After``` header indicates the time in seconds until the rate limits are reset.
