## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## 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`).

### Bugs, issues, features, and feedback

You can report issues on the Actor tab "Issues"
or [here](https://github.com/onidivo/apify-actors/issues/new?title==Load+Stress+Test+-+) and discuss or
leave your
feedback [here](https://github.com/onidivo/apify-actors/discussions).

### Input

You can provide input either through the editor on the Apify platform or as a JSON object.

The only mandatory field you need to provide is **URLs (urls)**.

```json
{
    "urls": [
        {
            "url": "https://bmwrepairguide.com/"
        }
    ],
    "maxUrlDuplications": 3,
    "maxCrawledPagesPerDomain": 3,
    "maxHandledPagesPerRun": 20,
    "proxyConfiguration": {
        "useApifyProxy": true
    },
    "maxHandledPagesPerTime": 5,
    "pageNavigationTimeoutMs": 90000
}

```

### Output

The output looks like this:

```json
{
    "url": "https://bmwrepairguide.com/",
    "originalUrl": "https://bmwrepairguide.com/",
    "duplicationId": 0,
    "pageTitle": "BMW Repair Guide - DIY repairs for your BMW",
    "loadTime": 0
}

# Changelog

This Actor's version history is a separate document: https://apify.com/onidivo/load-stress-test/changelog.md

# Actor input Schema

## `urls` (type: `array`):

A list of URLs to test.

## `maxUrlDuplications` (type: `integer`):

The maximum number of duplications per URL (either from the start or during the crawl).

## `maxCrawledPagesPerDomain` (type: `integer`):

The maximum number of crawled pages per URL domain (either from the start or during the crawl).

## `maxHandledPagesPerRun` (type: `integer`):

Defines how many pages to handle in total. Use this option to prevent running infinitely.

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

Use Apify Proxy or your custom Proxy.

## `maxHandledPagesPerTime` (type: `integer`):

Defines how many pages to process in parallel. The bot automatically increases and decreases this based on available system resources. Use this option to set a hard limit.

## `pageNavigationTimeoutMs` (type: `integer`):

Override the timeout for page navigation.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "urls": [
        {
            "url": "https://bmwrepairguide.com/"
        }

// Run the Actor and wait for it to finish
const run = await client.actor("onidivo/load-stress-test").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {

## CLI example

```bash
echo '{
  "urls": [
    {
      "url": "https://bmwrepairguide.com/"
    }
  ],
  "maxUrlDuplications": 0,

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,onidivo/load-stress-test"
        }
    }
}
```

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).
