## IntrospectionRequestValidator Class

Validates the introspection request properties and authenticates a client that initiated the request\.

```csharp
public class IntrospectionRequestValidator : Abblix.Oidc.Server.Endpoints.Introspection.Interfaces.IIntrospectionRequestValidator
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → IntrospectionRequestValidator

Implements [IIntrospectionRequestValidator](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Introspection.Interfaces.IIntrospectionRequestValidator 'Abblix\.Oidc\.Server\.Endpoints\.Introspection\.Interfaces\.IIntrospectionRequestValidator')

### Remarks
This class performs validation of introspection requests and client authentication\.
It ensures that the request is authorized and the provided token is valid for the client\.
The validation process includes checking the authenticity of the client and the integrity of the token\.
It leverages a client request authenticator for client authentication and a JWT validator for token validation\.
