## 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.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

Use this **Grainger scraper** as a **Grainger API alternative** to scrape **industrial MRO products** into clean JSON. Look up **product URLs**, **Grainger item # (SKU)**, **keywords / manufacturer part numbers**, or **category listings**, then export **item number**, **brand**, **list price**, **technical specifications**, **images**, **UNSPSC**, and **availability** for **Python**, **Node.js**, and **MCP** / AI assistants.

Ideal for procurement teams, MRO price monitoring, CMMS / ERP catalog sync, and multi-distributor sourcing pipelines alongside DigiKey and RS Online.

### MCP and AI assistants

Use this Actor from AI tools via [Apify MCP](https://docs.apify.com/platform/integrations/mcp). Connect your Apify account, then call `crawloop/grainger-scraper`.

Example prompts:

- "Run Grainger Scraper for item 5B359 and return brand, list price, UNSPSC, and specifications"

### Suite next step

After Grainger enrichment, compare electronics / industrial distributor coverage with [DigiKey Product Scraper](https://apify.com/crawloop/digikey-product-scraper) or [RS Online Scraper](https://apify.com/crawloop/rs-online-scraper). For automation OEM parts, continue with [Rockwell Product Scraper](https://apify.com/crawloop/rockwell-product-scraper).

### FAQ

**Is this a Grainger API?**\
No. It is an unofficial **Grainger API alternative** that scrapes publicly visible catalog pages into a structured dataset.

**Do I need a Grainger account?**\
No for public list-price / catalog fields. Contract prices and account-only stock are out of scope.

**Can I scrape Grainger with Python or Node.js?**\
Yes — use the Apify client examples above, or call the Actor from MCP / AI assistants.

**Why residential proxy?**\
Public catalog pages are bot-protected. Sticky Apify RESIDENTIAL US (or CA) sessions are required for reliable access.

**Why did my broad keyword return few products or an error?**\
Some broad queries redirect to a category hub. Use a more specific keyword, an item #, or a `categoryUrls` path.

**Listing vs product records?**\
`listing` rows come from search/category pages. Enable `enrichListingProducts` (or pass `productUrls` / `skus`) for full PDP fields including richer specs and prices.

# Actor input Schema

## `productUrls` (type: `array`):

Grainger product detail page URLs (…/product/…-{SKU}).

## `skus` (type: `array`):

Grainger item # / SKU values (e.g. 5B359). Resolved via search then enriched from the PDP when possible.

## `keywords` (type: `array`):

Catalog keyword or manufacturer part-number searches.

## `categoryUrls` (type: `array`):

Grainger /category/… URLs (or bare category paths like safety/eye-face-protection).

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

Stop after this many billable dataset items (product / listing).

## `maxPages` (type: `integer`):

Maximum listing pages per keyword or category URL.

## `enrichListingProducts` (type: `boolean`):

When scraping search/category listings, also fetch full PDP data for each row.

## `baseUrl` (type: `string`):

Grainger host for HTML scraping (US .com or Canada .ca).

## `requestDelaySecs` (type: `number`):

Pause between HTML navigations on the same browser session.

## `browserEngine` (type: `string`):

Camoufox is preferred against DataDome; Firefox is the fallback when Camoufox is unavailable.

## `proxyConfiguration` (type: `object`):

Apify Proxy settings. Sticky RESIDENTIAL US is strongly recommended — Grainger blocks datacenter and naive HTTP.

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
