## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## McMaster-Carr Product Scraper

![McMaster-Carr](https://media.licdn.com/dms/image/v2/D5622AQFoazgMwso6AA/feedshare-shrink_800/feedshare-shrink_800/0/1687195698355?e=2147483647\&v=beta\&t=Vm7q2aGq0PIbU86TL0TRknO-6HbjXbgOuZ7xdHml7No)

Scrapes product listings from [mcmaster.com](https://www.mcmaster.com) filtered category or search URLs.

### What it does

Given a McMaster-Carr filtered category URL, the actor extracts every product in the listing table: part number, price, dimensions, material group, and all other column values. Optionally, it visits each product's detail page to collect the full specifications table, primary image, and complete title.

### Input

Configure via the Apify Console or by editing `storage/key_value_stores/default/INPUT.json` for local runs.

| Field | Type | Required | Description |
|---|---|---|---|
| `url` | String | Yes | A McMaster-Carr filtered category URL (e.g. `https://www.mcmaster.com/products/eyebolts/body-style~eye-nut/`). Apply all desired filters in your browser first, then paste the resulting URL. |
| `maxItems` | Integer | No | Maximum number of product records to save. Omit or set to `null` for no limit. |
| `detailedInfo` | Boolean | No | When `true`, visits each product's detail page to collect the full specifications table, primary image, and precise title. Significantly increases run time. Default: `false`. |

**Example input:**

```json
{
  "url": "https://www.mcmaster.com/products/eyebolts/rope-guides-1~/",
  "maxItems": 100,
  "detailedInfo": false
}
```

### Output

Records are saved to the default Apify Dataset. Each record contains:

| Field | Description |
|---|---|
| `partNumber` | McMaster-Carr part number, e.g. `8491A301` |
| `url` | Absolute URL of the product detail page |
| `title` | Product category header from the listing page |
| `titleFull` | Full product name from the detail page *(detailedInfo only)* |
| `material` | Material group or dimensional group from the listing table |
| `subgroup` | Sub-group within the material group (React-table pages only) |
| `price` | Unit price at the lowest quantity tier, e.g. `$14.24` |
| `style` | Style letter, e.g. `A`, `B` (eyebolt-style pages) |
| `threadSize` | Thread size string, e.g. `3/8"-16` (eyebolt-style pages) |
| `overallLength` | Overall length, e.g. `2 1/4"` (eyebolt-style pages) |
| `eyeDiameter` | Eye inside diameter (eyebolt-style pages) |
| `verticalCapacityLb` | Vertical working load limit in pounds (eyebolt-style pages) |
| `specsMet` | Standards or specifications met. `null` when shown as `—` |
| `columnData` | Key→value map of **all** listing columns keyed by header text (classic-table pages, e.g. drill bushings). Contains all spec columns and tiered prices. |
| `imageUrl` | URL of the primary product image *(detailedInfo only)* |
| `specifications` | Key→value map of all spec-table entries from the detail page *(detailedInfo only)* |
| `scrapedAt` | ISO 8601 timestamp |

**Example record (drill bushing):**

```json
{
  "partNumber": "8491A301",
  "url": "https://www.mcmaster.com/8491A301",
  "title": "Press-Fit Drill Bushings",
  "material": "0.0135\" ID",
  "price": "$57.49",
  "columnData": {
    "OD": "5/32\"",
    "Lg.": "1/2\"",
    "For Drill Bit Size": "No. 80",
    "Drill Bushing Type": "P",
    "Material": "Steel",
    "Hardness": "Rockwell C61",
    "1-9": "$57.49",
    "10-49": "$54.30",
    "50-Up": "$51.44"
  },
  "scrapedAt": "2026-04-03T19:46:55.903Z"
}
```

### How to find the right URL

1. Go to [mcmaster.com](https://www.mcmaster.com) and search for a product category.
2. Use the left-hand filters to narrow results to the subset you want.
3. Copy the URL from your browser's address bar — it encodes all active filters.
4. Paste it into the `url` input field.

#### 💬 **Support and Feedback**

Need help or have suggestions? Leave a review on the Actor's Apify page or reach out via Apify support. We monitor McMaster's page structure and aim to keep the scraper up to date with any site changes.

# Actor input Schema

## `url` (type: `string`):

A McMaster-Carr filtered category URL (e.g. https://www.mcmaster.com/products/eyebolts/body-style~eye-nut/). Apply all desired filters in your browser first, then paste the resulting URL here. McMaster renders all matching products on a single page per filter combination.

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

Maximum number of product records to save. Scraping stops as soon as this count is reached. Omit or set to null for no limit.

## `detailedInfo` (type: `boolean`):

When enabled, the actor visits each product's detail page to collect the full specifications table, primary image, and precise title. Significantly increases run time and compute costs.

## Actor input object example

```json
{
  "url": "https://www.mcmaster.com/products/eyebolts/body-style~eye-nut/",
  "maxItems": 5,
  "detailedInfo": false
}
```
