 # 1688 Logistics Scraper

-Capture 1688 product pages and extract weight/size data via vision.
+Extract product weight, size, and logistics data from 1688 product pages.

 ## Run

 ```bash
-bun scripts/run.ts scrape <url> [--dry-run] [--port=9222]
+bun scripts/run.ts scrape <url> [--dry-run]
+```
+
+### Examples
+
+```bash
+bun scripts/run.ts scrape 'https://detail.1688.com/offer/852504650877.html'
+bun scripts/run.ts scrape 'https://detail.1688.com/offer/852504650877.html' --dry-run
 ```

 ## What It Does

-1. Opens the 1688 product URL in the browser (default port 18800)
-2. Scrolls through the entire page, capturing full-page screenshots
-3. Downloads all product detail images
-4. Saves to `/tmp/1688-logistics/<offer-id>/`
+1. Opens the 1688 product URL in the browser
+2. Extracts weight/size data from wherever it appears on the page — product attributes, variant specs, logistics section
+3. Downloads detail images (商品详情图片) for analysis — weight/size is often only in images
+4. Outputs structured JSON

-## After Running — MUST follow
+## Where To Look For Data

-Read ALL screenshots and detail images, then output the following JSON structure. This is the final output for API consumption.
+Weight/size data on 1688 pages hides in multiple places. Check all before giving up:
+
+1. **Product attributes** (商品属性 / 商品参数) — key-value table, most reliable
+2. **Variant/SKU specs** — per-variant weight or size
+3. **Logistics section** — shipping weight, volume, freight info
+4. **Detail images** — downloaded to `/tmp/1688-logistics/<offer-id>/`, read them to find weight/size text baked into images
+
+## Output

-### Field rules
-
- **All weight values normalized to kg** (克÷1000, 斤×0.5)
- **All dimension values normalized to cm** (mm÷10)
- **`source`**: where on the page the data was found (商品属性 / 商品件重尺 / 包装信息 / 详情图片)
- **`variants`**: only include if weight/size differs per SKU. Omit if all variants share the same specs.
- **Omit fields that are `null`** — do not include fields where no data was found
- **Do not guess.** Only include values actually visible on the page or in images.
+`null` = not found in text. Check `detailImages` — the data may be in the images.

 ## Rules

 1. If the browser is not running, report the error. Do not try to launch it.
-2. No retries. If it fails, report as-is.
-3. Read ALL screenshots — logistics data can appear anywhere on the page.
-4. Read detail images too — weight/size is often baked into product photos.
-5. Output ONLY the structured JSON above. No extra commentary.
+2. Check all data sources before reporting `null`.
+3. Normalize units: 克→kg, 毫米→cm. Keep raw values in `rawAttributes`.
+4. No retries. If it fails, report as-is.
+5. Trust page content. Do not guess values.
