The Optidash Image API enables you to fine-tune many visual aspects of your images. If you like to adjust saturation, brightness, or shadow details, you'll feel right at home. As with all API requests, you can combine multiple operations together to create truly unique visuals.

All manual adjustments must be passed in an adjust hash:

{
    "adjust": {
        "contrast": 20
    }
}

An example cURL request to adjust the contrast value will look like the following:

curl https://api.optidash.ai/1.0/fetch
     --user your-api-key: \
     --header "Content-Type: application/json" \
     --data '{
         "url": "https://www.website.com/image.jpg",
         "adjust": {
             "contrast": 20
         }
     }'
