## 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`).

## Trolley Grocery Price Scraper

> **Disclaimer:** Unofficial tool — not affiliated with, sponsored by, or endorsed by Trolley.co.uk or its affiliates. Data is read from publicly accessible search results, category lists, product pages, and deal lists only. No login. You are responsible for complying with applicable law (including GDPR where personal data appears) and the site’s terms. No warranty on accuracy or availability. Provided for informational and research use.

UK grocery price comparison in one row: the best listed price, unit price, and — on a category or product page — each supermarket’s price side by side. This Trolley scraper is an API alternative for basket checks and deal monitoring. Paste a keyword, a category slug, or a product URL. Run it from Python, Node.js, or MCP and export JSON.

### Use cases

- **Basket check** — open one product URL and read every supermarket price in `retailers`
- **Search export** — pull the best price and unit price for a keyword
- **Category shelf** — use `milks` and keep the shops nested on each row
- **Deal watch** — set `mode` to `deals` and `store` to Asda, then keep `regularPrice` and `priceDrop`

### FAQ

**Does search include every supermarket?**
Search rows are the card: best price, unit price, brand, and pack size. Set `mode` to `product` for each supermarket price and the weekly best-price series. Category rows already nest the shops shown on that list.

**Is the weekly series one price per supermarket?**
No. `priceHistory` is the best price by week on the product page. Each supermarket’s current price is in `retailers`.

**Which retailers can deals use?**
Asda, Sainsbury's, Morrisons, Co-op, Iceland, Boots, Superdrug, Savers, Amazon, and Ebay. Tesco and the other supermarkets still appear on product and category rows.

**What if the keyword matches nothing?**
The run finishes with an empty dataset. Other keywords in the same input still run.
