LimeWire AI API: Capabilities, Features, and Pricing

LimeWire AI API offers access to industry-leading generative AI models (DALL-E, BlueWillow, Stable Diffusion, Mubert, Stability AI, Google AI Imagen) to generate and transform images.

LimeWire AI APIs are built for developers, allowing straightforward integration with the business applications to offer generative AI capabilities to the end users. It supports integration with multiple programming languages like JavaScript, PHP, Python, Ruby, Java, C#, and Go. 

LimeWire AI API Capabilities

LimeWire AI API is a great option for developers looking to harness the capabilities of premier generative AI models, such as Stable Diffusion, DALL-E, and more. Currently, LimeWire offers APIs for image creation, upscaling, inpainting, and outpainting with text commands in easy-to-use JSON format.

The following sections illustrate LimeWire AI API capabilities in detail.

Text to Image Generation

Text-to-Image generation is where you describe the image and get the AI output. A user can deploy this API in 3 ways.

1. minimal: Uses the prompt and aspect ratio.

{
  "prompt": "A dog holding an umbrella in the rain", //image description
  "aspect_ratio": "1:1" // 1:1, 2:3, 3:2
}

2. prompt: Includes additional fields for negative prompt, number of samples, quality, guidance scale, etc.

{
  "prompt": "A dog holding an umbrella in the rain", //image description
  "negative_prompt": "darkness", //things to avoid
  "samples": 2, // 1 to 4 
  "quality": "LOW",  // LOW, MID, HIGH
  "guidance_scale": 50, // 1-100
  "aspect_ratio": "1:1", // 1:1, 2:3, 3:2
  "style": "PHOTOREALISTIC" // PHOTOREALISTIC, SCIFI, LANDSCAPE
}

3. prompt and image: Adds the image parameter to the prompt payload indicated previously.

{
  "prompt": "A dog holding an umbrella in the rain", //image description
  "negative_prompt": "darkness", //things to avoid
  "image_asset_id": "7be2d783-4826-406a-869e-d0ac1d344a37", //base image
  "samples": 2, // 1 to 4 
  "quality": "LOW",  // LOW, MID, HIGH
  "guidance_scale": 50, // 1-100
  "aspect_ratio": "1:1", // 1:1, 2:3, 3:2
  "style": "PHOTOREALISTIC" // PHOTOREALISTIC, SCIFI, LANDSCAPE
}

The last one gives maximum control over the generation, with a base image to affect the final output.

I will illustrate the “prompt” option first and leave “prompt and image” for the next section (Image to image generation).

{
  "prompt": "a nuclear wasteland with crumbling skyscrapers, toxic skies, eerie glow, mutated flora",
  "negative_prompt": "sunshine, trees",
  "samples": "1", // 1 to 4 
  "quality": "HIGH",  // LOW, MID, HIGH
  "guidance_scale": "60",  // 1-100
  "aspect_ratio": "3:2",  // 1:1, 2:3, 3:2
  "style": "PHOTOREALISTIC"  // PHOTOREALISTIC, SCIFI, LANDSCAPE
}

The response to the above API request is given below. Most importantly, you can check the API response status, credits used and remaining, output asset id, URL, and its dimensions.

        }
    ]
}

Resulting image:

I couldn’t have pictured anything better with the given prompt. LimeWire AI API included almost every detail as asked, including for the atmosphere, buildings, etc., whereas avoiding the elements of negative prompt.

A user can adjust the “guidance scale” to alter the influence of the prompt on the final output. In addition, “style” will offer more variations to pick from.

Image to Image Generation

LimeWire Image to Image generation API is meant to modify a base image with new elements. This uses the “prompt and image” format of the text to generation API discussed earlier.

For instance, I have created an image of a train carriage house.

{
  "prompt": "a train carriage house",
  "negative_prompt": "",
  "samples": "4",  // 1 to 4
  "quality": "MID",  // LOW, MID, HIGH
  "guidance_scale": "70",  // 1-100
  "aspect_ratio": "3:2",  // 1:1, 2:3, 3:2
  "style": "PHOTOREALISTIC"  // PHOTOREALISTIC, SCIFI, LANDSCAPE
}

The response gives out four samples as asked.

I have picked the asset_id of the best-looking image to use in the subsequent generation for changing the elements, including the train house windows and its overall aesthetics.

{
  "prompt": "glass windows with silver grills, antique, dark",
  "negative_prompt": "",
  "image_asset_id": "7be2d783-4826-406a-869e-d0ac1d344a37",

    ]
}

Now, look at both of these images to spot the subtle differences (from left to right), such as the rooftop, windows, track, etc. Everything goes from a polished, modern look to something giving a rustic & vintage vibes.

Overall, I’m pretty satisfied with this image-to-image generation API response.

Please note that this comes from the same API endpoint we used earlier in the text-to-image generation. The only difference is that you put an additional field for the base image, which gets modified with the latter prompt.

Image Outpainting

LimeWire Image Outpainting API is to extend the frame in one or all directions. The payload consists of three fields, including asset id, direction for outpainting, and cropping side.

{
  "image_asset_id": "81dd9fce-1e6d-412f-9ed9-f1a90edfbd94",
  "direction": "RIGHT",
  "crop_side": "LEFT"
}

The API payload asks to extend the frame in the right direction and allows cropping on the left.

{
    "id": "76cb2556-bd08-444f-9dbb-b95fdc37817c",
    "self": "https://api.limewire.com/api/request/76cb2556-bd08-444f-9dbb-b95fdc37817c",
    "status": "COMPLETED",

    "failure_reason": null,
    "credits_used": 1.5,
    "credits_remaining": 7413.06,

        {
            "asset_id": "03945d7e-7731-4f82-990c-db7241577b34",
            "self": "https://api.limewire.com/api/assets/03945d7e-7731-4f82-990c-db7241577b34",

            "width": 1088,
            "height": 640
        }
    ]
}

You can check the second image introduced a shrub on the right, which blends nicely in the frame. Overall, the outpainting output was okay. However, more control on the magnitude of frame extension would have made it even better.

Image Inpainting

Image Inpainting is for altering certain parts or adding additional elements to an existing image. A user can input the asset id of an existing image and prompt accordingly.

{
  "image_asset_id": "30c03d99-dfc5-4820-824d-5e6a2492cd37",
  "prompt": "a fountain"
}

Image Upscaling

LimeWire Image Upscaling API is used to increase the size of the image without any noticeable change in the quality. It’s extremely straightforward to use, with only two fields present for the asset_id and upscaling factor (1 to 4).

{
  "image_asset_id": "30c03d99-dfc5-4820-824d-5e6a2492cd37",
  "upscale_factor": 2
}

So, these were a few APIs available currently, and LimeWire has listed some more APIs, including for background removal and music and video generation, as coming soon. Besides, there is another API for uploading images to subsequently use for inpainting, outpainting, etc.

LimeWire AI API Limitations

LimeWire AI API may restrict a developer in some ways, including for the choice of AI models, upload limits, content availability, parallel requests, etc., as listed below.

• Can’t select preferred AI models: Currently, the process of selecting the AI model is automatic, which means a user cannot obtain responses from the generative AI model of their choice.
• Upload limit: LimeWire doesn’t let you upload files bigger than 10mb.
• Content Availability Limit: The user-generated and uploaded content stays live for 24 hours only.
• Capped concurrent requests: The number of simultaneous API calls is limited based on the subscription plan.
• AI creations: Like all AI tools, the images created by LimeWire AI aren’t perfect, and you might need to perform a few trials to get acceptable outputs. Plus, these AI tools are trained on data generated by human artists, posing questions about their ethical foundations.

LimeWire AI API Pricing

LimeWire AI API has four subscriptions tiers.

• API Basic: $29.99/month
• API Pro: $49.00/month
• API Pro Plus: $250.00/month
• API Enterprise: custom
