## Usage

- **API Endpoint**: `POST /alibaba1688/imageSearch` (see `references/api.md` for full parameters, responses, and error codes)
- **Python Script**: `python scripts/alibaba1688_image_search.py '<JSON parameters>'`

**Output strategy (script default behavior)**:
- Prints the full JSON response to stdout

**Data reading tip**: Use `jq` or `ConvertFrom-Json` to extract specific fields from the response as needed.

## Usage Examples

**1. Basic image search**
```
Search 1688 for products visually similar to this image: https://m.media-amazon.com/images/I/719mRAn2VrL._AC_SL1500_.jpg
```

**2. Search with filters**
```
Search 1688 for products similar to this image: https://m.media-amazon.com/images/I/719mRAn2VrL._AC_SL1500_.jpg -- filter by 1688 Premium Selection, sort by price descending, page 1
```

**3. Search with sorting**
```
Search 1688 for products similar to this image: https://example.com/product.jpg -- sort by price from high to low
```

**4. Paginated search**
```
Search 1688 for products similar to this image: https://example.com/product.jpg -- page 2, 50 results per page
```

**5. Price range filter**
```
Search 1688 for products similar to this image: https://example.com/product.jpg -- price range 10-100 CNY
```

## Display Rules

1. **Present data clearly**: Show results in a structured table with key columns: product image, title, price, dropship price, monthly sales, minimum order quantity, repurchase rate, and seller identity
2. **Image display**: When the response includes imageUrl for products, display them inline for visual comparison
3. **Price display**: Always show price in CNY format
4. **Seller badges**: Display seller identity badges (Super Factory / Verified Supplier / TrustPass member) and product badges (Premium Selection) prominently
5. **Result count**: Always inform the user of total results and current page/total pages
6. **Pagination hint**: When more pages are available, suggest the user can request the next page
7. **Filter/sort limitation**: If the user requests a sort or filter not in the supported list, do NOT attempt any workaround. Inform the user of the supported options
8. **No secondary processing**: Results are real-time and not stored in a database, so secondary SQL/data processing is not available

## Important Limitations

1. **Data real-time nature**: Results are live searches, not stored in any database.
2. **Logic constraint**: If the user requests sort or filter conditions not in the preset supported list, do NOT call any other tool or logic to compensate.
3. **Image input**: One of imageUrl, imageBase64, or imageId is required. For page > 1, prefer passing imageId from the first page result to speed up queries.
4. **Image format**: Only png, jpg, jpeg are supported. webp, gif, and other formats will be rejected.
5. **Base64 format**: The imageBase64 value must be the raw Base64 string only — do NOT include the `data:image/jpeg;base64,` prefix.
6. **Page size**: Maximum 50 results per page.
