How It Works

Asynchronous API for Maximum Reliability

Our API is built for asynchronous workflows. Submit a job, and we'll notify your application via webhook upon completion, ensuring no dropped connections and robust processing.

1. POST Request

Send a request to an upscale endpoint with your image URL and parameters. Our API immediately confirms the job is queued.

2. We Process

We handle the heavy lifting of AI upscaling on our scalable infrastructure. Your application doesn't need to wait or maintain a connection.

3. GET Webhook

Once complete, we send a payload to your webhook URL with the temporary (3-hour) URL to your high-resolution image.
