The SDXL Lightning API Documentation provides a comprehensive guide to utilizing the full power of the SDXL Lightning API for generating high-quality images from text inputs. With its advanced architecture designed for speed and precision, this API allows developers and businesses to seamlessly integrate text-to-image generation capabilities into their applications, websites, and interactive platforms. Whether you're creating custom artwork, enhancing user engagement, or developing innovative products, this documentation will help you unlock the full potential of the SDXL Lightning model.

API Parameters: The API POST- https://gateway.appypie.com/sdxl_lightning/getImage/v1/getSDXLImage, requires the following parameters:
Name | Required | Type | Description |
prompt | Yes | string | The prompts to guide the image generation |
negative_prompt | No | string | The prompt or prompts not to guide the image generation. |
height | No | Number, default 1024 | the height in pixels of the generated image. This is set to 1024 by default for the best results. Anything below 512 pixels won’t work well. |
width | No | Number, default 1024 | The width in pixels of the generated image. This is set to 1024 by default for the best results. |
num_inference_steps | No | Number, default 20, Maximum 20 | The number of denoising steps. More denoising steps usually lead to a higher-quality image at the expense of slower inference. |
guidance_scale | No | float, default 5.0 | Guidance scale is enabled by setting guidance_scale > 1. A higher guidance scale encourages generating images closely linked to the text prompt, usually at the expense of lower image quality. |
seed | No | 42 | The seed is used to reproduce results. Providing the same seed will yield the same image each time. Use “null” for a random number seed. |
