Image Generation API
Generate images on demand using a simple webhook trigger. A webhook receives user input, which is then sent to OpenAI's DALL-E model to create an image, and the image URL is returned via the webhook. This is useful for content creators needing quick visuals, developers integrating image generation into apps, or marketers creating ad creatives. It automates image creation, saving significant manual effort.
