### 2. Start the "Bulk PageSpeed Insights for a list of URLs" task

The Bulk PageSpeed Insights & Core Web Vitals Checker + Monitor Actor will start running based on the input automatically. You can also change all the input fields, like URLs to test, max pages taken from sitemaps, and more, to match your specific use case.

### 3. Receive the "Bulk PageSpeed Insights for a list of URLs" output

Monitor the progress in real time. You will be notified as soon as your dataset is complete and ready for review. Each result includes data such as screenshot, URL, device, and more.

### 4. Integrate into your workflow

## About this Actor

This example demonstrates how to use [Bulk PageSpeed Insights & Core Web Vitals Checker + Monitor](https://apify.com/tobbyb/pagespeed-core-web-vitals-monitor.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/tobbyb/pagespeed-core-web-vitals-monitor.md) to learn more, explore other use cases, and run it yourself.


## 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/tobbyb/pagespeed-core-web-vitals-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`).
