# Limiter

Another integration pattern is limiting the number of calls that can be made during a given period of time. This is important when rate limiting or billing may be an issue and is a perfect stop gap for a critical failure causing an erroneous number of API calls or running up an unwanted bill!

The Limiter auto resets it's count on the defined `TimeSpan`, and will not allow additional executions past the defined limit.

```csharp
using Perigee;
using Perigee.Extensions;

PerigeeApplication.ApplicationNoInit("Limiter", (c) =>
{

    c.AddRecurring("Limiter", (ct, l) => {
    using var APILimit = new RateLimiter("RateLimiter.json", 2, TimeSpan.FromMinutes(1), ct);

    if (APILimit.CanExecute())
    {
        //Perform action
        l.LogInformation("Calling API {n}/{x} executions", APILimit.GetCount(), APILimit.GetLimit());
    }
    else
    {
        l.LogInformation("Out of executions...");
    }
});
});

/*
 [16:35:07 INF] Calling API 1/2 executions
 [16:35:13 INF] Calling API 2/2 executions
 [16:35:18 INF] Out of executions...
 */
```
