## 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

## Social Caption & Hashtag Generator

Turn a one-line topic into a ready-to-post caption + hashtags for Instagram, TikTok, LinkedIn or X.

No scraping, no data collection — pure AI generation. Give it a topic, a platform, and optionally a tone, and get back a native-feeling caption plus 8-15 relevant hashtags.

### Input

```json
{
  "items": [
    { "topic": "Launch of a new eco-friendly water bottle", "platform": "instagram", "tone": "upbeat and inspiring" }
  ],
  "groqApiKey": "your-own-free-groq-key"
}
```

You need your own free Groq API key (get one at console.groq.com/keys, no cost) — this keeps the per-post price low since you're not paying for someone else's AI usage on top of the Actor fee.

### Output

```json
{
  "topic": "Launch of a new eco-friendly water bottle",
  "platform": "instagram",
  "caption": "🌊 Meet the bottle that gives the ocean back...",
  "hashtags": ["sustainability", "ecofriendly", "oceanplastic", "..."]
}
```

### Who this is for

- Social media managers batch-generating post drafts
- Small businesses without a dedicated marketing team
- Agents/automations that need to produce platform-native copy as part of a pipeline

### Pricing

Pay per use — no subscription:

- $0.01 per run
- $0.02 per post generated

# Actor input Schema

## `items` (type: `array`):

One entry per post you want generated. Each item needs a topic and a platform.

## `groqApiKey` (type: `string`):

Your own free Groq API key (console.groq.com/keys). Required -- the Actor uses it to generate the text, you are never charged by us for AI usage.

## Actor input object example

```json
{
  "items": [
    {
      "topic": "Launch of a new eco-friendly water bottle, made from recycled ocean plastic",
      "platform": "instagram",
      "tone": "upbeat and inspiring"
    }
  ]
}
```

# 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 = {
    "items": [
        {
            "topic": "Launch of a new eco-friendly water bottle, made from recycled ocean plastic",
            "platform": "instagram",
            "tone": "upbeat and inspiring"
        }
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("victor187/social-caption-hashtag-generator").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 = { "items": [{
            "topic": "Launch of a new eco-friendly water bottle, made from recycled ocean plastic",
            "platform": "instagram",
            "tone": "upbeat and inspiring",
        }] }

# Run the Actor and wait for it to finish
run = client.actor("victor187/social-caption-hashtag-generator").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 '{
  "items": [
    {
      "topic": "Launch of a new eco-friendly water bottle, made from recycled ocean plastic",
      "platform": "instagram",
      "tone": "upbeat and inspiring"
    }
  ]
}' |
apify call victor187/social-caption-hashtag-generator --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,victor187/social-caption-hashtag-generator"
        }
    }
}
```

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).
