## 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

## Threads Watchdog: New & Deleted Threads + Reposts

> **Watches any Threads account 24/7.** Get instant alerts when they post a new thread, share a repost, delete a post, or update their bio.

***

#### What It Does

- 🎯 **Audits Top 25–30 Timeline Items:** Automatically monitors the public profile stream (~25–30 items). Because Threads mixes posts and reposts chronologically, this captures the top ~20–25 original threads and top ~4–10 recent reposts. Newly published items are saved into rolling memory (up to 50 items) so you never miss a deletion.
- 🧵 **New Thread Alerts:** Instant notifications when an account publishes a new thread, photo, or link with full text and author info.
- 🔄 **New Repost Alerts:** Know the moment an account amplifies third-party content.
- 🚨 **Catches Deleted Threads & Un-Reposts:** Alerts if a thread is deleted or if a repost is quietly removed, with the full original text.
- ✏️ **Watches Bio & Avatar Updates:** Shows before and after diffs when a creator changes their bio, photo, or handle.
- 👥 **Tracks Multiple Accounts:** Monitor multiple executives or competitors in one task (e.g. `zuck, mosseri`).

***

#### 💎 Simple Flat Pricing ($0.0007 per Check)

Flat, predictable developer pricing with **zero result fees**. You only pay for the check — all thread, repost, and deletion alerts are included for free.

| Item | Price |
| :--- | :--- |
| **Account Check** | **$0.0007** per account checked (~$0.70 per 1,000 checks) |
| **Deleted Thread & Un-Repost Alerts** | **$0.00 (FREE)** |
| **New Thread & Repost Alerts** | **$0.00 (FREE)** |
| **Profile & Bio Alerts** | **$0.00 (FREE)** |

##### Monthly Cost Scenarios (Developer Fee):

- **Checking 1 account every 15 minutes:** **$2.01 / month** (regardless of how many threads they post or delete).
- **Checking 1 account every 30 minutes:** **$1.00 / month**.
- **Checking 5 accounts every 15 minutes:** **$10.08 / month**.

> 💡 **Platform Usage Transparency:**\
> This Actor stores only lightweight state metadata (~15 KB) in your Key-Value Store. It does not store raw video files, so storage usage is practically zero and remains well within Apify's free storage allowance. Runs use standard minimal Apify compute (~1–2 seconds on 128MB RAM).

***

#### How to Use

1. **Enter Username(s):** Type any Threads username (e.g. `zuck` or multiple separated by commas).
2. **Click Start:** Run it once to save the initial snapshot, then schedule it to run automatically every 5, 15, or 30 minutes.
3. **Get Alerts:** Receive notifications via Email, Slack, Discord, or Webhooks whenever an account posts or changes anything.

***

# 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 = {
    "username": "verge"
};

// Run the Actor and wait for it to finish
const run = await client.actor("socialwatchdog/threads-watchdog").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);
});

# Prepare the Actor input
run_input = { "username": "verge" }

# Run the Actor and wait for it to finish

## CLI example

```bash
echo '{
  "username": "verge"
}' |
apify call socialwatchdog/threads-watchdog --silent --output-dataset

```

## MCP server setup

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

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).
