## 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

## Indie Launch Radar — Show HN Early-Traction Scanner

Find early-stage SaaS and indie products **gaining real organic traction** on Hacker News — before they hit everyone's radar.

This Actor scans **Show HN** launches and ranks them by a **traction score** that rewards *velocity* (points per hour) and *genuine discussion* (comment-to-point ratio), not just raw vote counts. It's built for indie hackers, scouts, and investors who want signal, not noise.

### What it does

- Pulls Show HN launches from the last *N* days via the public Hacker News (Algolia) API
- Filters out low-signal posts (configurable minimum points & comments)
- Optional keyword filter (e.g. `ai`, `b2b`, `developer tools`)
- Scores each launch 0–10 on organic traction and sorts best-first

No proxy, no login, no API key required.

### Input

| Field | Type | Default | Description |
|---|---|---|---|
| `daysBack` | integer | `7` | How many days of launches to scan (1–30) |
| `minPoints` | integer | `20` | Discard launches below this many points |
| `minComments` | integer | `3` | Discard launches below this many comments |
| `keywords` | array | `[]` | Keep only titles matching a keyword (empty = all) |
| `maxResults` | integer | `100` | Cap on launches returned |

#### Example input

```json
{
  "daysBack": 7,
  "minPoints": 30,
  "minComments": 5,
  "keywords": ["ai", "saas", "b2b"],
  "maxResults": 50
}
````

### Output

Each item in the dataset:

```json
{
  "title": "MyTool – open-source X for Y",
  "url": "https://mytool.com",
  "points": 142,
  "numComments": 38,
  "ageHours": 19.2,
  "tractionScore": 7.4,
  "author": "janedoe",
  "hnUrl": "https://news.ycombinator.com/item?id=00000000",
  "createdAt": "2026-06-01T10:00:00.000Z"
}
```

A `SUMMARY` record is also saved to the key-value store with scan counts and the top launch.

### How the traction score works

`tractionScore` (0–10) blends three organic signals:

- **Velocity** (40%) — points per hour since posting. The strongest early signal.
- **Discussion** (30%) — comments per point. Real engagement, hard to fake.
- **Volume** (30%) — log-scaled point floor so tiny posts can't top the list.

### Use cases

- Spot indie SaaS launches in their first 24–72h window
- Build a weekly "launch radar" newsletter or dashboard
- Source deals or competitive intel by keyword/category

# 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 = {};

// Run the Actor and wait for it to finish
const run = await client.actor("agency-shift/indie-launch-radar-show-hn-early-traction-scanner").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) => {
