## 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?

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.

# README

## Public Job Board Change Monitor Actor

Status: local MVP ready for Apify packaging review.

This Apify-style actor extracts likely job listing links from public career pages and compares them against a previous job snapshot. It emits normalized job records plus `new`, `unchanged`, and `removed` change records.

### Safe Use Boundary

- Public career pages and public job board result pages only.
- No account login, private workspace access, CAPTCHA handling, MFA, or evasion.
- No hidden API abuse or high-frequency polling.
- Buyers are responsible for using it only where public monitoring is allowed.

### Input

```json
{
  "pages": [
    {
      "url": "https://example.com/jobs",
      "previous_jobs": [
        {
          "title": "Data Engineer",
          "url": "https://example.com/jobs/data-engineer",
          "signature": "data-engineer|https://example.com/jobs/data-engineer"
        }
      ]
    }
  ]
}
```

For offline demos or controlled tests, each page can include an `html` string.

### Output

The local CLI returns a summary object:

- `pages[].jobs`: current normalized job listings.
- `pages[].changes`: change records with `change_type` of `new`, `unchanged`, or `removed`.
- `pages[].stats`: link count and dedupe stats.

The Apify-compatible `main.py` writes JSONL dataset records with `record_type` of `job` or `change`.

### Local Commands

```powershell
C:\Users\lauku\.cache\codex-runtimes\codex-primary-runtime\dependencies\python\python.exe -m unittest discover -s tests -v
C:\Users\lauku\.cache\codex-runtimes\codex-primary-runtime\dependencies\python\python.exe .\job_board_monitor.py --input .\samples\input.json --out .\samples\output.json
C:\Users\lauku\.cache\codex-runtimes\codex-primary-runtime\dependencies\python\python.exe .\main.py
```

### Differentiator

Most basic job scrapers focus on one vendor or only dump listings. This actor is deliberately generic for public pages and change-oriented: it returns stable signatures and removed-listing detection so it can feed alerts, applicant tracking research, or market monitoring workflows without private account access.

# Actor input Schema

## `pages` (type: `array`):

Public career pages or job board result pages to inspect. Do not provide login-only or private URLs.

## Actor input object example

```json
{
  "pages": [
    {
      "url": "https://example.com/jobs"
    }
  ]
}
```

# Actor output Schema

## `results` (type: `string`):

Default dataset records produced by the actor.

# 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 = {
    "pages": [
        {
            "url": "https://example.com/jobs"
        }
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("eager_vitamin/my-actor").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 = { "pages": [{ "url": "https://example.com/jobs" }] }

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

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