https://api.useapi.net/v1/runwayml/image_upscaler/?…

Request Headers 
Authorization: Bearer {API token}
Query Parameters
  • email is optional when only one account configured. However, if you have multiple accounts configured, this parameter becomes required.
  • image_url is required. Image URL should be either the URL provided by text_to_image_preview or an asset URL from GET /assets. You may need to upload the image using POST /assets and use the URL provided for this parameter.
  • weight is required. Specify image width.
  • height is required. Specify image height.
Responses
Model 
Binary stream in case of HTTP 200 response. 

Otherwise see type provided below:
{ // TypeScript, all fields are optional
    error: string,
    message: string,
    code: number
}
Examples 
  • curl "https://api.useapi.net/v1/runwayml/image_upscaler/?image_url=https://…image.jpg&width=100&height=100" \
   -H "Accept: application/json" \
   -o resized_image.jpg

  • const token = "API token";
const image_url="https://…image.jpg";
const width = 100;
const height = 200;
const apiUrl = `https://api.useapi.net/v1/runwayml/image_upscaler/?image_url=${image_url}&width=${width}&height=${height}`; 
const response = await fetch(apiUrl, {
  headers: {
    "Authorization": `Bearer ${token}`,
  },
});
console.log("response", {response, result});
// response.blob() contains resized image
// • Node.js saving resized image to file:
// response.blob()
//     .then(blob => blob.arrayBuffer())
//     .then(buffer => fs.writeFile('resized_image.jpg', Buffer.from(buffer)));
// • Displaying response as an image on the webpage, as you see below in Try It section:
// const imageBlob = await response.blob();
// const imageUrl = URL.createObjectURL(imageBlob);
// const imageElement = document.getElementById('your-image-id');
// imageElement.src = imageUrl;

# from io import BytesIO
# from PIL import Image
