# GitHub Trending Repos & Star Velocity Delta Monitor (`titan_coder/github-trending-repos-delta`) Actor

Zero-browser, API-first open-source intelligence. Detects breakout GitHub repositories and sudden star acceleration before they hit mainstream newsletters. Stores previous star counts in memory and delivers clean delta alerts.

## 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

## GitHub Trending Repos & Star Velocity Delta Monitor (Save 90%)

> 🛑 **Stop pulling hundreds of static repositories to find the few that are truly trending.** Traditional scrapers don't calculate star velocity, making it impossible to catch early momentum.\
> ⚡ **The Smart Delta Solution:** **GitHub Trending Repos & Star Velocity Delta Monitor** queries GitHub's official REST API with zero browser overhead (running in 1–2s), tracks star counts across runs in persistent storage, and delivers alerts **ONLY** when a new project breaks out or surges in star velocity — **saving 90% compute.**

***

### ⚡ Why Use This Actor?

- **Zero-Browser, 100% Lightweight:** Avoids fragile browser scraping. Uses direct REST APIs with instant execution in **1 to 2 seconds**.
- **Smart Delta Memory:** Maintains historical star counts in persistent Key-Value storage. Zero duplicate noise in your feeds.
- **Pay-Per-Event (PPE):** Unchanged periods cost $0 in event fees.
- **Developer, VC & Recruiter OSINT:** Identify viral tools, new AI frameworks, and emerging tech stacks days before they reach Hacker News or Twitter.

***

### 🔍 Tracked Events

- `NEW_TRENDING_REPO`: A newly indexed repository crossed your minimum star threshold.
- `STAR_VELOCITY_SURGE`: An existing repository experienced a star acceleration surge (>30% growth).

# 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 = {
    "language": "python",
    "minStars": 50,
    "maxRepos": 10,
    "trackNewTrending": true,
    "trackStarVelocity": true,
    "resetBaseline": false
};

// Run the Actor and wait for it to finish
const run = await client.actor("titan_coder/github-trending-repos-delta").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 = {
    "language": "python",
    "minStars": 50,
    "maxRepos": 10,
    "trackNewTrending": True,
    "trackStarVelocity": True,
    "resetBaseline": False,
}

# Run the Actor and wait for it to finish
run = client.actor("titan_coder/github-trending-repos-delta").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 '{
  "language": "python",
  "minStars": 50,
  "maxRepos": 10,
  "trackNewTrending": true,
  "trackStarVelocity": true,
  "resetBaseline": false

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,titan_coder/github-trending-repos-delta"
        }
    }
}
```

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).
