import org.springframework.web.client.RestClient;

public class SuperCompressClient {
    private final RestClient restClient;
    private final String apiKey;

    public SuperCompressClient(String apiKey) {
        this.apiKey = apiKey;
        this.restClient = RestClient.create();
    }

    public String compress(String context, String query) {
        var request = new CompressRequest(context, query);
        var response = restClient.post()
            .uri("https://supercompress.dev/api/v1/compress")
            .header("X-API-Key", apiKey)
            .body(request)
            .retrieve()
            .body(CompressResponse.class);

}

Frequently asked questions

Does it work with Spring AI?

Yes. Call compress() before passing context to Spring AI's template-based prompt builders.

Can I use it with Quarkus?

Yes. The REST API is framework-agnostic. Use Quarkus's REST Client reactive with the same endpoint.
