Introduction
Second-hand marketplaces face a consistent pain point: static product photos fail to convey the depth, trust, and engagement that video can deliver. Enter Sora 2, a cost-efficient AI video generation tool that transforms static images into dynamic showcase videos.
Why Static Product Listings Fall Short
Trust Gap in Second-Hand Marketplaces
- Buyers often hesitate because images can hide defects.
- Missing context on product dimensions or movement.
Low Engagement and Conversion
- Static media struggles to hold attention.
- Video fosters connection and a sense of authenticity.

API Workflow for Image + Video
Step 1: Generate Product Images
Use Nano Banana API models to generate high-quality product images quickly.
Example:
curl --location --request POST 'https://wisdom-gate.juheapi.com/v1/chat/completions' \
--header 'Authorization: sk-XXXX' \
--header 'Content-Type: application/json' \
--header 'Accept: */*' \
--data-raw '{
"model": "gemini-2.5-flash-image",
"messages": [{"role": "user","content": [{"text": "generate a high-quality image.","type": "text"},
{"image_url": {"url": "https://blog-images.juhedata.cloud/9105_output_1794ff4b.jpeg"},"type": "image_url/base64"}]}],
"stream": false
}'
Step 2: Create AI Showcase Video
Generate the video using the Sora 2 model:
curl -X POST "https://wisdom-gate.juheapi.com/v1/videos" \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: multipart/form-data" \
-F model="sora-2" \
-F prompt="A serene lake surrounded by mountains at sunset" \
-F seconds="15"
Replace prompt with a detailed product description.
Step 3: Track Progress Asynchronously
Check task status without blocking your process:
curl -X GET "https://wisdom-gate.juheapi.com/v1/videos/{task_id}" \
-H "Authorization: Bearer YOUR_API_KEY"
