## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## Craigslist New Listings Monitor — Delta Scraper

Monitor any Craigslist search and get **only the listings that appeared since your last run**. No duplicates, no noise — just what's new. Schedule it hourly or daily and never miss a deal again.

---

### 🎯 Who is this for?

- **Deal hunters** who want to be the first to respond to a new listing
- **Resellers** monitoring specific keywords for underpriced items (electronics, furniture, bikes)
- **Job seekers** tracking fresh postings in their city without refreshing the page all day
- **Developers** building price alert systems or Craigslist notification bots
- **Researchers** tracking listing volume and price trends over time

---

### ⚡ How the delta detection works

- **First run** — scrapes all current listings matching your search, saves their IDs to a Key-Value Store
- **Next runs** — scrapes again, compares against saved IDs, returns **only listings it hasn't seen before**
- **Scheduled runs** — runs automatically on your chosen interval; each run picks up where the last left off

Seen IDs older than 30 days are automatically purged to keep storage lean.

---

### 🔄 Schedule hourly or daily alerts

This actor is designed to run on a schedule. Set it up once and get a stream of new listings automatically.

1. Open the actor and click **Schedule**
2. Set the interval (every hour, every day — your choice)
3. New listings appear in your dataset each run, ready to export or pipe into a webhook

No code required. No email setup. Just results.

> **Tip:** run once with `notifyOnlyNew: false` to get a full baseline, then switch to `true` for all scheduled runs.
