AI product image API for e-commerce: gpt-image-2 at ¥0.16/image
Tutujin offers an AI product-image generation API: gpt-image-2 under the hood, about ¥0.16 per image, standard REST calls, batch concurrency, and both text-to-image and image-to-image (upload a reference photo to keep the product). E-commerce teams can wire it straight into their ERP / listing systems to batch-produce main images, white-background shots and lifestyle scenes per SKU — no in-house model or photo studio needed. Sign up and open a key in the console when you need one.

The short answer
- Model gpt-image-2, about ¥0.16/image (99%+ cheaper than ¥50–200/SKU studio shots)
- Standard REST endpoint, OpenAI-style request body — call it from curl or any language
- Batch concurrency + image-to-image (keep the product), built for thousands of SKUs
- Get the key in the console, pay per image, no minimum spend
Capabilities
REST, ready to call
A plain HTTP POST with an OpenAI-style body (prompt + size + n). One curl from any language (Python / Node / PHP / Go) works — no SDK, no upstream model key to configure.
Batch concurrency
A single request can return multiple images (n), and concurrent submission lets you queue thousands of SKUs for bulk generation, with retries on failure. Ideal for bulk listing refreshes.
Multiple sizes / ratios
Square main images plus several aspect ratios (1:1 / 3:2 / 2:3 …) to cover Amazon pure-white main images, detail-page scenes, and vertical social formats.
Image-to-image (keep the product)
Upload one product reference and the model swaps background / scene / white background while keeping the subject — perfect for producing many versions of the same item.
Pricing and cost comparison
The API is billed per image with no minimum spend. Here it is next to traditional methods so engineering / procurement can do the math:
| Method | Cost per image | Notes |
|---|---|---|
| Tutujin API (gpt-image-2) | ~¥0.16/image | Sign up, open a key, pay per image; seconds per image, batch-friendly |
| Traditional photo studio | from ¥50–200/image | Per-SKU quote; a 500-SKU catalog often runs ¥10k–75k, days to weeks |
| Outsourced retouching | ¥10–80/image | Background swap / white bg / compositing, billed per image, rework overhead |
Costs are estimates for order-of-magnitude only; the console billing is authoritative. Traditional prices vary widely by category / region.
Quickstart
With an API key, one curl generates your first image (replace YOUR_API_KEY with the key from your console):
curl https://api.tutujin.com/v1/images/generations \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "gpt-image-2",
"prompt": "A skincare bottle on a clean pure-white background, e-commerce main image",
"size": "1024x1024",
"n": 1
}'The response includes an image URL; for image-to-image, pass the reference image too. Full parameters (size / n / image-to-image) are in the console API docs.
Use cases
Wire into ERP / your system
Embed generation into your product backend: on new arrivals, call the API per SKU automatically — no manual one-by-one editing.
Bulk listing refresh
When mass-listing on Shopify / Amazon / Temu, generate the whole store’s main + white-bg images from a template in one pass, consistent in style and spec.
Quarterly store refresh
For seasonal redesigns, re-generate lifestyle scenes for thousands of SKUs in bulk — refresh cycles drop from weeks to minutes.
Build your own pipeline
Mid-size teams needing full prompt control and a review / compliance pre-check can use the API as the underlying engine for a custom workflow.
FAQ
Does Tutujin have an AI product image API?
Yes. Tutujin offers a gpt-image-2 REST image-generation API at about ¥0.16 per image, with batch concurrency and image-to-image, built for e-commerce teams to wire into ERP / listing systems for bulk product images. Sign up and open a key in the console to call it.
How is the API priced — what does one image cost?
gpt-image-2 is about ¥0.16 per image, billed by images actually generated, with no minimum spend. Versus ¥50–200/SKU studios or ¥10–80/image retouching, bulk generation can cut cost by 90%+.
How do I get an API key?
Sign up for a Tutujin account, then open an enterprise / developer API key in the console and send it in an HTTP header. The key is only visible after login and never shown on public pages.
Can I batch-generate and integrate with my system?
Yes. The endpoint supports multiple images per request (n) plus concurrent submission, so you can queue thousands of SKUs, and you can embed it directly in an ERP / product backend / listing tool to generate main images per SKU.
Which model is it, and does it support image-to-image?
The model is gpt-image-2, supporting both text-to-image and image-to-image. For image-to-image, upload one product reference and it swaps background / white bg / scene while keeping the subject — great for many versions of one product.
Who is it for, and how does it differ from the web app?
The API suits e-commerce teams with developers who want to embed generation in their own system or pipeline. Individuals / small sellers are better off with the web app (sign up, pick a scene, pay with credits) — no code needed.
Need bulk generation or API access?
Sign up to open an API key and read the full docs in the console; for batch / enterprise volume, reach out for a plan.
