## Pricing

$15.00/month + usage

To use this Actor, you pay a monthly rental fee to the developer. The rent is subtracted from your prepaid usage every month after the free trial period. You also pay for the Apify platform usage, which gets cheaper the higher Apify subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

- **Generate customized traffic** to test your website tools and integrations (e.g, analytics, SEO, and ADs).

### Cost of usage

When running the actor with memory of **4096 MB** using datacenter proxies, average consumption is about **$2** usage
credits and **90 minutes** per **1000 results**.

### 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
}
```

# 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.

## Actor input object example

```json
{
  "urls": [
    {
      "url": "https://bmwrepairguide.com/"
    }
  ],
  "maxUrlDuplications": 10,
  "maxCrawledPagesPerDomain": 10,
  "maxHandledPagesPerRun": 20,
  "proxyConfiguration": {
    "useApifyProxy": true
  },
  "maxHandledPagesPerTime": 50,
  "pageNavigationTimeoutMs": 60000
}
```

# 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.

    token: '<YOUR_API_TOKEN>',
});

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

## 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>")

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

apify call onidivo/load-stress-test --silent --output-dataset

```

## 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).
