> WebExtrator Web Render & Extract 集成指南 - Ace Data Cloud

`POST https://api.acedata.cloud/webextrator/extract`

Content extraction based on `/webextrator/render`. In addition to all parameters of the render interface, it additionally supports:

| Field           | Type    | Required | Default    | Description                                                                          |
| --------------- | ------- | :------: | ---------- | ------------------------------------------------------------------------------------ |
| `expected_type` | string  |     ❌    | `markdown` | Expected extraction output: `markdown` / `article` / `text` / `links` / `structured` |
| `enable_llm`    | boolean |     ❌    | false      | Enable LLM post-processing (suitable for `article` / `structured`)                   |
| `instruction`   | string  |     ❌    | -          | LLM extraction instructions, e.g., "extract product title, price, specifications"    |

  -d '{
    "url": "https://example.com/news/1",
