# Check the latest version of npm packages

**Use case:** 

Check the latest published version of every npm package in a list, with its license, description and required Node.js version, from the public npm registry. Packages that do not exist come back as 404 rows. Useful for dependency audits, license checks and keeping a spreadsheet of package versions up to date on a schedule.

## Input

```json
{
  "url": "https://registry.npmjs.org/{{package|url}}/latest",
  "method": "GET",
  "headers": {},
  "queryParams": {},
  "csv": "package\nreact\nexpress\nlodash\n@apify/log\nnext\nthis-package-does-not-exist-xyz",
  "maxRows": 0,

  "perHostPerSecond": 5,
  "maxRetries": 2,
  "timeoutSecs": 30,

### 2. Start the "Check the latest version of npm packages" task

The Bulk HTTP Requests — API Calls for Clay, n8n, CSV & Datasets Actor will start running based on the input automatically. You can also change all the input fields, like URL template, method, and more, to match your specific use case.

### 3. Receive the "Check the latest version of npm packages" 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 #, method, URL, and more.

### 4. Integrate into your workflow

## About this Actor

This example demonstrates how to use [Bulk HTTP Requests — API Calls for Clay, n8n, CSV & Datasets](https://apify.com/saliga/bulk-http-requests.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/saliga/bulk-http-requests.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/saliga/bulk-http-requests.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`).
