eBay AI listing photos: the seller owns accuracy

eBay's User Agreement says you assume full responsibility for the accuracy and content of your listing, including content made with image editing or generative AI tools. So the image must show the item you are actually selling. Generate from your own photo with Sume, then check the result against the item.

What the policy says

The eBay User Agreement, read on 2026-10-03, says sellers assume "full responsibility for the item offered and the accuracy and content of the listing", including listing content created with tools such as translation, image editing and generative AI. Read the live page before each batch, since policies change. This post does not cover eBay's video or photo size rules, which were not verified.

Edit your real photo to a square still

POST /v1/images takes input_references for image-to-image, with public HTTPS URLs, and aspect_ratio 1:1 for a square. The docs say ChatGPT Image 2.5 (openai/gpt-image-2.5) supports up to 16 references. Using the real photo as the reference keeps the generated still anchored to the actual item. The route blocks up to 30 seconds and returns the image with 200, or a job envelope with 202.

Read supported_parameters from GET /v1/images/models before pinning values.

curl -X POST https://api.sume.com/v1/images \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-image-2.5",
    "prompt": "The same item on a plain white background, soft even light, no props",
    "input_references": [
      { "type": "image_url", "image_url": { "url": "https://example.com/my-actual-item.jpg" } }
    ],
    "aspect_ratio": "1:1"
  }'

Check before you list

Compare the generated still against the item itself, not against the photo. Generated edits can change a logo, a scratch, a color or a count of parts, and each of those is an accuracy problem in a listing.

Keep your original photos, and show real condition shots for wear that matters.

• Check color, text, logos and the number of parts.
• Do not add accessories or features that are not in the box.
• Re-read eBay's current policy before each batch.
• Keep the original photo with your records.
