=== Using camel annotations from LangChain4j AI service method parameters

The `camel-quarkus-langchain4j` extension make it possible to use camel parameter binding annotations with LangChain4j AI services.

Let's see an example below:

```
@RegisterAiService
@ApplicationScoped
public interface CustomAiService {

    @UserMessage("An LLM prompt that can use the method parameter {myHeaderInjectedIntoPrompt}.")
    @Handler
    String invokeLlm(@Header("myHeaderName") String myHeaderInjectedIntoPrompt);
}
```

You can find more details about Camel Parameter Binding annotations in the xref:manual::parameter-binding-annotations.adoc[manual].
