## 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`).

# README

## Example Apify actor in Rust

Minimal example for developing Apify actor in [Rust programming language](https://www.rust-lang.org/). The code is [open source](https://github.com/metalwarrior665/rust-apify-actor-example).

The example:

- Reads user provided URL from input
- Does HTTP request to get HTML from this URL
- Saves HTML into OUTPUT record in Key Value Store

This actor works both on Apify platform and locally.

### Local usage

For local usage, you need to:

1. Clone the [repository](https://github.com/metalwarrior665/rust-apify-actor-example)
2. [Install Rust](https://www.rust-lang.org/tools/install)
3. Create local storage with `apify init` or manually create folder path `apify_storage/key_value_stores/default/`
4. Add `INPUT.json` file input inside this path that looks like this:

```json
{
    "url": "https://apify.com"
}
```

5. Build and run the solution with `cargo run`
6. You can find `OUTPUT.html` next to `INPUT.json`

### Current problems

- Apify currently doesn't allow increasing memory for builds so they sometimes fails by running out of memory
- Apify caches the Docker images on its servers. Rust is not yet used much there so a lot of runs have slow cold starts.

# Actor input Schema

## `url` (type: `string`):

URL to scrape and extract HTML from

## Actor input object example

```json
{
  "url": "https://apify.com"
}
```

# 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 = {
    "url": "https://apify.com"
};

// Run the Actor and wait for it to finish
const run = await client.actor("lukaskrivka/rust-actor-example").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 = { "url": "https://apify.com" }

# Run the Actor and wait for it to finish
run = client.actor("lukaskrivka/rust-actor-example").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "url": "https://apify.com"
}' |
apify call lukaskrivka/rust-actor-example --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,lukaskrivka/rust-actor-example"
        }
    }
}
```

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).
