How the ClarityAI Upscaler API Works on Wireflow

The ClarityAI Crystal upscaler runs as a processing node inside Wireflow. You build a workflow containing the upscaler, publish it, then call the execute endpoint with your image URL. Wireflow handles GPU allocation, queuing, and delivery. The node accepts any raster image and returns a 4x-resolution PNG with enhanced detail, powered by a multi-stage pipeline that combines ESRGAN pre-upscaling, ControlNet Tile guidance, and Stable Diffusion refinement.

Because the upscaler is a standard Wireflow node, you can chain it after any generation model. Generate an image with Recraft V4 or Nano Banana 2, pipe the output into ClarityAI Crystal, and retrieve the final high-resolution result from a single API call. No intermediate downloads, no manual steps.

ClarityAI Upscaler API Capabilities

🔍

4x Resolution Upscaling

Enhance images to four times their original resolution while preserving structure and adding realistic detail.

🔗

REST API Execution

Trigger upscaling via a single POST request and poll for results with standard HTTP, no SDK required.

⚡

Pipeline Chaining

Wire the upscaler after any image generation node to produce high-resolution output in one automated run.

🎛️

Creativity Control

Adjust the diffusion strength parameter to balance between faithful upscaling and creative detail enhancement.

🔄

Webhook Triggers

Fire upscaling jobs from external systems using webhook URLs that require no API key on the trigger call.

📊

Execution Polling

Track job status with the poll endpoint and retrieve completed results including timing and credit usage data.

More Than Just ClarityAI Upscaler API

Native Upscaling Node

The ClarityAI Crystal upscaler runs as a first-class processing node, same as every other model on the AI image upscaler page.

FAQs

What resolution does the ClarityAI upscaler produce?
The ClarityAI Crystal upscaler enhances images to 4x their original resolution. A 512x512 input becomes 2048x2048, with added detail generated by a multi-stage diffusion pipeline.
How do I call the ClarityAI upscaler via API?
Build a workflow with the upscaler node on Wireflow, then POST to the execute endpoint with your image URL. Poll the execution ID until the status returns COMPLETED with your upscaled image.
Can I chain the upscaler with image generation?
Yes. Connect any generation node like Recraft V4 or Nano Banana 2 before the ClarityAI Crystal node. One API call executes the full pipeline and returns the upscaled result.
What authentication does the upscaler API require?
You need a Wireflow API key starting with sk-, passed as a Bearer token in the Authorization header. Keys are generated from Settings in the Wireflow dashboard.
What image formats does the upscaler accept?
The upscaler accepts JPEG, PNG, and WebP inputs via URL. Output is returned as a high-resolution PNG with enhanced detail and preserved structural fidelity.
How long does upscaling take through the API?
Processing typically takes 10 to 20 seconds depending on input size and queue depth. Use the poll endpoint with exponential backoff starting at 1 second intervals.
What is the difference between Creative and Crystal modes?
Crystal mode prioritizes fidelity to the source image with minimal hallucination. Creative mode adds more generated detail, useful for artistic enhancement but less faithful to the original.
Can I trigger upscaling without an API key?
Yes, using webhooks. Publish your workflow with a webhook URL, then POST to the trigger endpoint. No API key is needed on the trigger call, making it easy to connect from forms or CI pipelines.
