## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use 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.

# 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
}

import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "url": "https://www.mcmaster.com/products/eyebolts/body-style~eye-nut/",
    "maxItems": 5
};

// Run the Actor and wait for it to finish
const run = await client.actor("ocrad/mcmaster-product-scraper").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
