# Limits HTTP headers responses

Each Alephee API request will include the following rate limit response headers:

| Header key             | Description                                                                                 | Key value type |
| ---------------------- | ------------------------------------------------------------------------------------------- | -------------- |
| x-ratelimit-limit      | Total requests that can be done in a given period, times per minute.                        | integer        |
| x-ratelimit-remaining  | Number of remaining requests to completely fill the rate limit.                             | integer        |
| x-ratelimit-reset      | The number of seconds until the limit will reset to its maximum capacity.                   | integer        |
| x-ratelimit-retryafter | The number of seconds until the user should retry, and always -1 if the action was allowed. | integer        |

These headers are present in the RESPONSE HEADERS of each HTTP API request. They are not available in the response JSON body of any API endpoint request.
