Introduction

The client library for Java offers an easy-to-use interface to interact with Sunra’s services.

​
Installation

To integrate the client into your project, install it using npm:

implementation("ai.sunra.client:sunra-client:0.1.4")

​
Features

​
Calling Endpoints

Sunra manages endpoint requests through a queue system, ensuring reliability and scalability. Use the subscribe method to submit a request and await the result.

Example:

import ai.sunra.client.*;
import ai.sunra.client.queue.*;
import java.util.Map;
import com.google.gson.JsonObject;
import java.util.function.Consumer;

ClientConfig config = ClientConfig.builder()
    .withCredentials(CredentialsResolver.fromEnv())
    .build();

SunraClient client = SunraClient.withConfig(config);
Map<String, Object> input = Map.of(
    "prompt", "a dog running in the park");

Consumer<QueueStatus.StatusUpdate> statusUpdateHandler = update -> {
    String status = update.getStatus().toString();
    String message = String.format("\nStatus Update: %s, Request ID: %s",
        status, update.getRequestId());
    System.out.println(message);
};

SubscribeOptions<JsonObject> options = SubscribeOptions.<JsonObject>builder()
    .input(input)
    .resultType(JsonObject.class)
    .onQueueUpdate(statusUpdateHandler)
    .logs(true)
    .build();

// save the subscribe request to a variable and print it
Output<JsonObject> response = client.subscribe("black-forest-labs/flux-kontext-pro/text-to-image", options);
System.out.println("Completed!");
System.out.println(response.getData());

​
Queue Management

Manage your requests with these methods:

Submitting a Request

Submit a request and retrieve the request_id for later use.

Example:

import ai.sunra.client.*;
import ai.sunra.client.queue.*;
import java.util.Map;
import com.google.gson.JsonObject;
import java.util.function.Consumer;

ClientConfig config = ClientConfig.builder()
    .withCredentials(CredentialsResolver.fromEnv())
    .build();

SunraClient client = SunraClient.withConfig(config);
Map<String, Object> input = Map.of(
    "prompt", "a dog running in the park");

Consumer<QueueStatus.StatusUpdate> statusUpdateHandler = update -> {
    String status = update.getStatus().toString();
    String message = String.format("\nStatus Update: %s, Request ID: %s",
        status, update.getRequestId());
    System.out.println(message);
};

SubscribeOptions<JsonObject> options = SubscribeOptions.<JsonObject>builder()
    .input(input)
    .resultType(JsonObject.class)
    .onQueueUpdate(statusUpdateHandler)
    .logs(true)
    .build();

// save the subscribe request to a variable and print it
var request = client.queue().submit("black-forest-labs/flux-kontext-pro/text-to-image", options);
Checking Request Status

Retrieve the status of a request.

Example:

import ai.sunra.client.*;
import ai.sunra.client.queue.*;

ClientConfig config = ClientConfig.builder()
    .withCredentials(CredentialsResolver.fromEnv())
    .build();

SunraClient client = SunraClient.withConfig(config);
var job = client.queue().status(QueueStatusOptions.withRequestId("pd_eTYYuw4EqYLzRBHgnAMHA8zH"));
Retrieving Request Results

Fetch the result of a completed request.

Example:

import ai.sunra.client.*;
import ai.sunra.client.queue.*;

ClientConfig config = ClientConfig.builder()
    .withCredentials(CredentialsResolver.fromEnv())
    .build();

SunraClient client = SunraClient.withConfig(config);
var result = client.queue().result(QueueStatusOptions.withRequestId("pd_eTYYuw4EqYLzRBHgnAMHA8zH"));
