## 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

## Hacker News Startup Signal Tracker

Track Hacker News startup, launch, and technology signals using the public Algolia API.

HTTP-only, no browser, no login, no proxy. Designed for low-cost Apify runs and commercial pay-per-result datasets.

# Actor input Schema

## `maxResults` (type: `integer`):

Maximum records to output. Keep small for cheap runs.

## `minScore` (type: `integer`):

Only output records with opportunity\_score at least this value.

## `includeSummary` (type: `boolean`):

Store SUMMARY in the key-value store.

## `queries` (type: `array`):

queries used by this Actor.

## Actor input object example

```json
{
  "maxResults": 25,
  "minScore": 0,
  "includeSummary": true,
  "queries": [
    "Show HN",
    "startup",
    "AI",
    "SaaS",
    "launch"
  ]
}
```

# Actor output Schema

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

Default dataset items.

## `summary` (type: `string`):

SUMMARY key-value record.

# 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 = {
    "queries": [
        "Show HN",
        "startup",
        "AI",
        "SaaS",
        "launch"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("viniman27/hacker-news-startup-signal-tracker").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 = { "queries": [
        "Show HN",
        "startup",
        "AI",
        "SaaS",
        "launch",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("viniman27/hacker-news-startup-signal-tracker").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)
