API

Call Z-Image

Every model takes the same request, so switching to Z-Image is a change to the model field. These samples are written for its own contract and send as they are.

import Mynth from "@mynthio/sdk";

const mynth = new Mynth();

const task = await mynth.image.generate({
  model: "tongyi-mai/z-image",
  prompt: "A lighthouse at dusk, 35mm film",
  size: "16:9",
});

console.log(task.urls[0]);
