E-commerce mode produces alt text optimized for product listings — emphasizing specific product attributes rather than general visual description.

​
How it activates

E-commerce mode activates automatically when you include any product metadata in your request. There is no separate toggle. API — include any field in the ecommerce object: 
{
  "imageUrl": "https://example.com/sneaker.jpg",
  "ecommerce": {
    "product": "sneakers",
    "brand": "Nike",
    "color": "black",
    "material": "leather"
  }
}
All e-commerce integrations include metadata settings where you can select which product fields to pass. E-commerce mode activates automatically when at least one field is provided.
Pass as many product fields as possible. The more context the model has — brand, color, material, product name — the more precise and consistent the output will be across your catalog.

​
Output differences

ModeExample output
DefaultA person wearing joggers in a park, mid-stride.
E-commerceBlack Nike joggers in polyester fabric — relaxed fit.

​
Style interaction

When e-commerce mode is active, the selected writing style has lower priority. Output stays concise and attribute-focused regardless of the style setting. This ensures consistency across product listings.
