PaidREST API for GPT-image-1 text-to-image and image editing
What is 4oImageAPI.io?
4oImageAPI.io gives developers a REST endpoint for OpenAI's GPT-image-1 model, covering text-to-image and image-to-image generation. It is aimed at teams that want to add image generation to their own apps without working with OpenAI directly.
Requests are sent with a bearer token and can include up to several source image URLs, a prompt, an aspect ratio and a callback URL that receives the result when generation finishes. Code samples are given in Python and JavaScript, and documentation covers each parameter.
The service highlights accurate text inside images, style transfer across photorealistic and illustrated looks, and outputs in PNG, JPEG and WebP up to 4K. Pricing is not shown on the homepage.
