## 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`).

### Data Sources

1. **Blockchain Explorers**:
   - Etherscan (Ethereum)
   - BSCScan (Binance Smart Chain)
   - PolygonScan (Polygon)
   - SolScan (Solana)

2. **GitHub API**: Repository statistics and development activity

3. **Website Analysis**: Metadata extraction and social media link detection

### Risk Scoring Algorithm

The risk score (0-100, lower is better) considers:

- **Contract Verification**: -20 points if verified
- **Holder Count**: -10 points if >1,000 holders
- **GitHub Activity**: -10 points if >100 stars, -5 if high activity
- **Website Presence**: -5 points if professional website
- **Social Media**: -2 points each for Twitter/Telegram presence

### Configuration

Environment variables:

- `ETHERSCAN_API_KEY`: Etherscan API key
- `BSCSCAN_API_KEY`: BSCScan API key
- `POLYGONSCAN_API_KEY`: PolygonScan API key
- `GITHUB_TOKEN`: GitHub API token (optional, for higher rate limits)
- `HTTP_TIMEOUT_SECS`: HTTP request timeout (default: 15)
- `MAX_PARALLEL_REQUESTS`: Concurrent request limit (default: 5)

### Pricing

- **Free Tier**: Up to 10 tokens per run
- **Standard**: $0.05 per token analyzed
- **Premium**: $0.02 per token (bulk pricing for >1,000 tokens/month)
- **Enterprise**: Custom pricing with SLA guarantees

### Use Cases

- **Due Diligence**: Comprehensive token research and risk assessment
- **Portfolio Management**: Automated metadata collection for holdings
- **Investment Analysis**: Compare projects across multiple dimensions

# 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 = {
    "tokens": [
        {
            "symbol": "USDC",
            "chain": "ethereum",
            "contract": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",

            "github": "https://github.com/centrehq/centre-tokens"
        }
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("natalietdg/coinhawk-metadata-engine").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) => {

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,natalietdg/coinhawk-metadata-engine"
        }
    }
}
```

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).
