Q: What does a generation request look like?

POST to /v1/images/generations with model , prompt and optionally n and size . The format matches the OpenAI Images API — only the base URL and the key change.

Q: How do I set the image size?

A data array where each item holds a link to the finished image in the url field. Download the picture and store it on your side — the link is not meant for permanent hosting.
