“I would shortlist Krea and Leonardo, with Krea as the first integration to prototype.”
“REST API and official SDK.”
“Access to 20+ image models.”
“Image generation and image editing workflows.”
“Image upscaling, including high-resolution outputs.”
“Custom LoRA training.”
“Video generation APIs.”
“It also supports asynchronous generation jobs, making it suitable for applications where image generation takes several seconds.”
“Its API uses compute-unit pricing, with published per-generation pricing and no charge for failed jobs, according to its documentation.”
“Midjourney Not recommended for integration”
“Excellent creative benchmark, but not a viable official API integration today.”
“No public REST API or official developer SDK.”
“No supported programmatic image-generation workflow.”
“Midjourney's terms prohibit automated tools accessing or generating assets through its services.”
“The account suspension, reliability and terms-of-service risks aren't worth it.”
“I would shortlist Krea and Leonardo, with Krea as the first integration to prototype.”
“Leonardo has a mature API offering and is particularly interesting if you want control over generation styles and custom models.”
“Official REST API.”
“Text-to-image and image-to-image generation.”
“Image-to-video generation.”
“Custom model and LoRA training.”
“Custom presets.”
“Image upscaling and editing.”
“Pay-as-you-go API credits.”
“Higher-volume plans with custom concurrency limits.”
“One particularly useful feature is that Leonardo lets you experiment visually in its interface and export the corresponding API code.”
