## 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

## Hacker News Technology Radar

**Price:** $0.05 per usable bounded technology radar.

Turn a bounded current top-story sample from the official Hacker News API into an attention radar without returning users, titles or text.

### Input

Provide 1–5 short technology terms and choose 5–20 current top-story IDs to sample. Terms are normalized and counted only against fetched story titles.

### Output

One row reports valid sample size, median score/discussion, top external domains, term mention counts and limited story ID/link evidence. It is an attention proxy, not sentiment, market size or a forecast.

### Pricing

$0.05 for one usable `radar-created` row, atomically charged with the dataset push. Zero mentions remain useful and billable; an empty valid-story sample or source failure is not.

### Limits

One list request plus at most twenty item requests run sequentially with two seconds between starts, a 2 MiB response cap, 15 second HTTP timeout, and 180 second run timeout. Item identity mismatch and malformed data fail explicitly.

### Privacy

Usernames, profiles, titles, story text and comment text are never returned. Only story IDs, external links/domains and aggregate score/comment counts are retained. Hacker News is the source and does not endorse this product.

# Actor input Schema

## `terms` (type: `array`):

One to five short terms counted against the current top-story titles.

## `maxStories` (type: `integer`):

Number of top-story IDs fetched and considered.

## Actor input object example

```json
{
  "terms": [
    "python",
    "database"
  ],
  "maxStories": 10
}
```

# 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 = {
    "terms": [
        "python",
        "database"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("jpmarketdata/hackernews-technology-radar").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 = { "terms": [
        "python",
        "database",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("jpmarketdata/hackernews-technology-radar").call(run_input=run_input)

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

## CLI example

```bash
echo '{
  "terms": [
    "python",
    "database"
  ]
}' |
apify call jpmarketdata/hackernews-technology-radar --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,jpmarketdata/hackernews-technology-radar"
        }
    }
}
```

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).
