Virtual try-on API.
One call, any product.

import { Genlook } from "@genlook/api";
import { readFile } from "node:fs/promises";

const client = new Genlook({ apiKey: process.env.GENLOOK_API_KEY! });

// 1. Upload the customer photo once, reuse the imageId.
const { imageId } = await client.images.upload(
  await readFile("./customer.jpg"),
  { mimeType: "image/jpeg" },
);

// 2. Create the try-on. The product is created inline.
const { generationId } = await client.tryOn.create({
  products: [{
    externalId: "hoodie-42",
    title: "Oversized cotton hoodie",
    description: "Relaxed fit, dropped shoulders, hip length.",
    images: [{ source: { url: "https://cdn.example.com/hoodie.jpg" } }],
  }],
  person: { image: { source: { id: imageId } } },
});

// 3. Wait for the result (or use a webhook).
const result = await client.generations.waitFor(generationId);
console.log(result.resultImageUrl);
