## 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`).

### 🆚 Why PageSpeed Scores API vs. Standard Google API

| Feature | PageSpeed Scores API | Standard Google REST API |
| :--- | :--- | :--- |
| **API Key Requirement** | ⚡ Keyless (Zero API Key needed) | ❌ Mandatory API Key required |
| **Agentic Browsing (2/2)** | ✅ Included in JSON response | ❌ Not available in raw v5 API |
| **Audit Recommendations** | ✅ Included (Unused JS, ARIA, Links) | ❌ Raw unparsed audit trees |
| **Daily Quota Limits** | 🚀 Unthrottled Keyless RPC | 🐢 Strict 429 Rate Limits / Quotas |
| **Anti-Blocking** | ✅ 100% Procedural UA Randomization | ❌ Single IP / Key Rate Tracking |

***

### 💡 How To Use — Simple Workflow

1. **Enter URL** → Enter target website URL (e.g. `https://apify.com`).
2. **Select Strategy** → Select `mobile` or `desktop`.
3. **Run & Export** → Click **Start** to extract scores and export to JSON/CSV.

## CLI example

```bash
echo '{
  "url": "https://apify.com",
  "strategy": "mobile"
}' |
apify call dev00/google-pagespeed-insights-api --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,dev00/google-pagespeed-insights-api"
        }
    }
}
```

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).
