# Monitor an eBay iPhone listing price

**Use case:** 

Replace the example URL with an eBay item you want to watch. The first run stores and returns its baseline. Repeat sequentially with the same watchlist name to receive observed NEW or UPDATED records; an unchanged repeat returns a free summary plus the page-check fee. No schedule is created.

```json

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

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 full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/luminar/ebay-product-scraper-price-monitor.md

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`).
