Topaz API SDK for RunAPI

Topaz API SDKs for JavaScript, Python, Ruby, Go, and Java on RunAPI.

The Topaz API SDK packages JavaScript, Python, Ruby, Go, and Java clients for Topaz on RunAPI. Use it for image and video upscaling workflows when your app needs typed request builders, predictable task polling, file upload helpers, account helpers, and consistent RunAPI errors.

Topaz is listed in the RunAPI model catalog at https://runapi.ai/models/topaz. Variant pages below carry pricing, rate-limit, and commercial-usage details. The public topaz-sdk repository groups the language packages, examples, CI, and release tags for this model.

Install

npm install @runapi.ai/topaz
pip install runapi-topaz
gem install runapi-topaz
go get github.com/runapi-ai/topaz-sdk/go@latest

Gradle:

dependencies {
  implementation("ai.runapi:runapi-topaz:0.1.0")
}

Maven:

<dependency>
  <groupId>ai.runapi</groupId>
  <artifactId>runapi-topaz</artifactId>
  <version>0.1.0</version>
</dependency>

Use the Java BOM when installing multiple RunAPI Java modules:

dependencies {
  implementation(platform("ai.runapi:runapi-bom:0.1.0"))
  implementation("ai.runapi:runapi-topaz")
}

What you can build

• Build apps, agent workflows, batch jobs, and production services around Topaz requests.
• Install only the language package your app needs while keeping one model-specific repository for docs and releases.
• Use create for submit-only jobs, get for status lookup, and run for submit-and-poll scripts.
• Upload local files, URL files, or base64 files through shared RunAPI file helpers.
• Handle validation, authentication, rate limits, insufficient credits, task failures, and polling timeouts through RunAPI SDK errors.

Java quick start

import ai.runapi.topaz.TopazClient;
import ai.runapi.topaz.types.UpscaleImageParams;
import ai.runapi.topaz.types.CompletedUpscaleImageResponse;
import ai.runapi.topaz.types.UpscaleImageModel;

TopazClient client = TopazClient.builder()
    .apiKey(System.getenv("RUNAPI_API_KEY"))
    .build();

CompletedUpscaleImageResponse result = client.upscaleImage().run(
    UpscaleImageParams.builder()
        .model(UpscaleImageModel.TOPAZ_UPSCALE_IMAGE)
        .sourceImageUrl("https://cdn.runapi.ai/public/samples/image.jpg")
        .upscaleFactor(2)
        .build()
);

Java packages target Java 8 bytecode and are tested on Java 8, 11, 17, and 21. Each model artifact depends on ai.runapi:runapi-core, so application code normally installs only ai.runapi:runapi-topaz.

Task lifecycle

Most media endpoints are asynchronous. create() submits a task and returns its id, get(id) fetches the latest task state, and run(params) creates the task and polls until it reaches a terminal state. In web request handlers, prefer create() plus webhook or later get() polling so the server does not hold a worker open.

FAQ

Which package should I install for Topaz work?

Install the model package for your language: @runapi.ai/topaz on npm, runapi-topaz on PyPI, runapi-topaz on RubyGems, github.com/runapi-ai/topaz-sdk/go, or ai.runapi:runapi-topaz. Install core SDK packages only when you are building shared SDK infrastructure.

Where should public links point?

Primary Topaz links point to https://runapi.ai/models/topaz. Pricing and usage-policy links point to variant pages such as https://runapi.ai/models/topaz/upscale-image. Provider comparisons point to https://runapi.ai/providers/topaz, and broad browsing points to https://runapi.ai/models.
