## Pricing

from $1.50 / 1,000 listing results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

### 📌 What is lmjx.net Used Machinery Scraper?

lmjx.net runs one of China's largest road-machinery portals, including a used-equipment marketplace with **~97,000 excavator ads and ~70,000 roller ads** alone. There is no public API. This actor reads the marketplace's mobile pages over plain HTTP (no browser, no captcha solving) and returns clean, normalised records.

Use it to:

- 📊 **Benchmark Chinese used-equipment prices** by brand, category and region
- 🔎 **Source machines from China** (Komatsu, Caterpillar, Sany, XCMG, Liugong, Hitachi, Volvo…)
- 🏭 **Map dealers and sellers** (company name, store URL, listing volume)
- 🔄 **Monitor the market** with scheduled runs

### 📋 Data fields

Every record follows the normalised **Rastriq machinery schema** (identical across our Chinese marketplace actors).

| Field | Type | Description |
|---|---|---|
| `source`, `sourceSection` | string | `lmjx.net`, `used` |
| `listingId`, `url` | string | Listing ID and URL |
| `title` | string | Original title (Chinese) |
| `category`, `categoryPath` | string, array | Category as shown on the site; `categoryPath` = site category tree (e.g. `二手工程机械 › 土方机械 › 挖掘机`) |
| `brand`, `model` | string | Brand (Chinese); model (details mode, or parsed from title) |
| `year`, `hours` | integer | Year / operating hours (details mode, or parsed from title) |
| `condition` | string | Always `used` |
| `priceCny`, `priceText`, `priceType` | number, string, string | Price in CNY (万元 converted), original text, `fixed` / `range_min` / `on_request` |
| `location` | object | `{province, city, raw}` (details mode) |
| `seller` | object | `{name, type, shopUrl}` — `type`: company / dealer / individual |
| `images` | array | Absolute https image URLs |
| `specs` | object | Extra attributes (e.g. origin) |
| `updatedAt` | string | ISO 8601 last update (details mode) |
| `qualityFlags` | array | Data-quality flags — see below |
| `ext_categorySlug`, `ext_categoryEn` | string | Site category slug and its English name (e.g. `wajueji`, `Excavators`) |
| `ext_*` | mixed | Site-specific: condition grade (`9成新`), unit, views, description, store opening date |
| `scrapedAt` | string | ISO 8601 UTC |

**Quality flags** (rows are flagged, never dropped): `price_on_request`, `price_suspect_low`, `brand_missing`, `multi_model_ad` (one ad covering many models), `service_ad` (repair/rental/wanted ads), `year_from_title`, `hours_from_title`, `model_from_title`, `location_missing`, `detail_fetch_failed`, `contact_scrubbed`, `no_images`.

### 🚀 How to use

1. Open the actor and keep the defaults (category *Excavators*, 10 listings).
2. Pick one or more **categories** from the dropdown (168 entries: 25 groups and 143 subcategories; a group such as *Earthmoving machinery (all)* downloads all its subcategories), optionally a **brand** and/or a **region** (province or city) from the dropdowns.
3. Tick **Fetch detail pages** if you need region, hours, model, photos and update date.
4. Click **Start** and download the dataset.

### 💰 Cost

Pay-per-event pricing — you pay only for items that land in your dataset, never for retries or failed pages. Higher Apify plans get automatic volume discounts:

| Event (per 1,000 results) | Free | Bronze | Silver | Gold | Platinum | Diamond |
|---|---|---|---|---|---|---|
| **Listing result** (Fetch detail pages off) | $2.00 | $1.80 | $1.70 | $1.50 | $1.30 | $1.20 |
| **Detailed result** (Fetch detail pages on) | $4.00 | $3.60 | $3.40 | $3.00 | $2.60 | $2.40 |

Plus **$0.005 per run** (Actor start). Each item is charged **either** as a listing result **or** as a detailed result — never both; if a detail page cannot be fetched, that item is charged at the listing price.

*Example:* 1,000 items with details on the Free plan ≈ **$4.00**; 10,000 listing-only items ≈ **$20.00**.

Platform compute is included in the price. **Proxy:** not needed by default. If you add your own proxy (for example a residential proxy) in *Proxy URL*, that traffic is billed by your proxy provider and is **not** included in the Actor price. Use *Max items* or the run's *Maximum cost per run* to cap your spend.

Speed: List-only runs need ~0.05 HTTP requests per result (20 listings per page), so compute cost is negligible; detail runs need ~1.1 requests per result.

### ⚠️ Known limits

- **Data quality is the site's.** Many ads are dealer batch posts covering several models at once (`multi_model_ad`) or are services rather than machines (`service_ad`). About half of the ads say 面议 (price on request).
- **Year and hours** are present only when the seller wrote them in the title (typical for region pages such as `beijing`) or in the detail page (hours only). They are flagged `*_from_title`.
- Location, hours, model and photos need `includeDetails`.
- The site sits behind a WAF that occasionally answers with a captcha page (~10% of requests when fetching detail pages quickly); the actor retries with backoff and skips what it cannot get. Keep concurrency ≤ 4.
- The actor does not read the desktop host `ershou.lmjx.net` (slider captcha); it uses the equivalent mobile host.
- Only the used marketplace is covered. The new-equipment pages of lmjx.net do not publish prices.

### ❓ FAQ

**Does it collect phone numbers or WeChat IDs?** No. Phone numbers, WeChat/QQ IDs and e-mails are never extracted, and are stripped from titles and descriptions (`contact_scrubbed`). Optionally, a company contact *name* can be included.

**Can I get all 97,000 excavators?** Yes with `maxItems: 0`; at the default pace that is about 4,800 requests (roughly 30-60 minutes list-only). Splitting by brand or province is recommended.

**Are prices in CNY?** Yes; `万元` is converted to yuan. `priceText` keeps the original text.

**Is scraping legal?** The actor reads publicly visible pages and respects the site's robots.txt for the paths used. You are responsible for using the data in line with applicable law and the site's terms.

# Actor input Schema

## `categories` (type: `array`):

Pick one or more used-equipment categories from the site's own tree (type to filter, English or Chinese). <b>Choosing a parent such as “Earthmoving machinery (all)” downloads all its subcategories</b>; each subcategory is crawled separately, so the per-category page cap never applies. Categories are merged (deduplicated) with the <b>Start URLs</b> below; leave both empty to get the default (Excavators). Excavators alone have ~97,000 listings.

## `brand` (type: `string`):

Restrict to one brand (type to filter, English or Chinese). The list holds the 219 brands the site lists; any other site slug typed by hand (e.g. <code>komatsu</code>) is also accepted. A brand only returns results in the categories where the site carries it. Applies to every selected category.

## `province` (type: `string`):

Restrict to a province, municipality or city (type to filter, English or Chinese). Region pages list per-unit ads with year/hours in the title (best data quality). A province includes all its cities. Applies to every selected category.

## `startUrls` (type: `array`):

Optional listing URLs from <code>mershou.lmjx.net</code> (or <code>ershou.lmjx.net</code>), e.g. <code>https://mershou.lmjx.net/yaluji/xcmg/</code>. Pagination is followed automatically. They are merged with the categories selected above (clear the category selection to crawl only these URLs). Query strings are never used (the site's robots.txt disallows them).

## `maxItems` (type: `integer`):

Maximum number of results. Use a small value (5-20) for a first test. Set to <code>0</code> for no limit.

## `includeDetails` (type: `boolean`):

Adds <b>model, operating hours, condition grade, province/city, all photos, update date, views and store link</b>. Costs +1 request per listing (≈20× slower). Without it you still get title, brand, seller company, price and a thumbnail.

## `includeSellerContact` (type: `boolean`):

Adds the contact person's name shown on the store page, <b>only for company sellers</b> and only together with detail pages. Phone numbers and e-mails are never extracted. Off by default.

## `maxConcurrency` (type: `integer`):

Parallel requests (1-10). Default 3.

## `requestDelayMs` (type: `integer`):

Base delay before each request, with ±50% random jitter.

## `proxyUrl` (type: `string`):

Optional proxy, e.g. <code>http://user:pass@gate.decodo.com:7000</code>. Leave empty to connect directly (works for both sites). <b>Proxy traffic is billed by your own proxy provider</b> and is not included in this Actor's price. Recommended (residential, China or Asia exit) if your runs show repeated HTTP 405 captcha blocks.

## `debugMode` (type: `boolean`):

Log every request URL.

## Actor input object example

```json
{
  "categories": [
    "wajueji"
  ],
  "maxItems": 10,
  "includeDetails": false,
  "includeSellerContact": false,
  "maxConcurrency": 3,
  "requestDelayMs": 500,
  "debugMode": false
}
```

# Actor output Schema
