## 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

## 💰 Crypto Price Tracker

Monitor the rapidly shifting landscape of decentralized finance by automatically tracking thousands of emerging altcoins and established cryptocurrencies. This advanced token price tracker is explicitly built to monitor live market data straight from target websites, covering an expansive roster of over 10,000 digital assets. Instead of manually refreshing various crypto ranking pages, you can configure this tool to automatically run daily or weekly monitoring sweeps across your highly customized token watchlists. It efficiently captures the vital details you need to evaluate market momentum, including real-time fiat prices, circulating supply metrics, and acute 24-hour volume spikes. Active researchers and quantitative analysts use this tool to systematically discover micro-cap opportunities and track portfolio health long before these specific assets hit mainstream trading tools or major exchanges. The generated results give you a highly granular look at the overall market, outputting current valuations, localized currency conversions, and moving percentage changes directly from public endpoints. With absolutely zero authentication hurdles, you can seamlessly schedule tasks to pull live pricing data and pipe the scraped results directly into your own analytical models. By treating financial websites as a reliable API, this tracker empowers you to build robust automated alerts for sudden market movements and token liquidity events.

### API Usage

Run this actor programmatically using the Apify API. Replace `YOUR_API_TOKEN` with your token from [Apify Console → Settings → Integrations](https://console.apify.com/account/integrations).

#### cURL

```bash
curl -X POST "https://api.apify.com/v2/acts/taroyamada~cryptocurrency-price-tracker/run-sync-get-dataset-items?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "coins": ["bitcoin", "ethereum", "solana"], "vsCurrencies": ["usd", "jpy"], "includeHistory": false }'
```

#### Python

```python
from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("taroyamada/cryptocurrency-price-tracker").call(run_input={
  "coins": ["bitcoin", "ethereum", "solana"],
  "vsCurrencies": ["usd", "jpy"],
  "includeHistory": false
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)
```

#### JavaScript / Node.js

```javascript
import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });
const run = await client.actor('taroyamada/cryptocurrency-price-tracker').call({
  "coins": ["bitcoin", "ethereum", "solana"],
  "vsCurrencies": ["usd", "jpy"],
  "includeHistory": false
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);
```

### Tips & Limitations

- Powered by CoinGecko's free public API — no API key required.
- Schedule every 5 minutes for near-real-time price tracking.
- Use multiple `vsCurrencies` to monitor cross-currency arbitrage opportunities.
- Combine with webhook delivery to send alerts on threshold breaches.

### FAQ

**Rate limits?**

CoinGecko free tier: ~30 calls/min. This actor batches requests to stay safe.

**Where do coin IDs come from?**

Use CoinGecko's coin list (e.g., 'bitcoin', not 'BTC'). The actor validates IDs at input time.

**Can I get real-time prices?**

CoinGecko free tier has 1-5 min cache. For sub-minute, paid tier needed.

**Historical data retention?**

Free tier: 365 days of daily data. Older history requires paid tier.

**Which exchanges does the price come from?**

CoinGecko aggregates volume-weighted prices across hundreds of exchanges.

**Is there a rate limit?**

CoinGecko free tier allows ~30 calls/minute. The actor batches requests automatically.
