How to Use the Cryptonator API

Using the Cryptonator API is straightforward. All endpoints follow a simple URL structure:

https://api.cryptonator.com/api/{base}-{quote}/{action}

Where:

{base} is the cryptocurrency you're querying (e.g., btc for Bitcoin)
{quote} is the target currency (e.g., usd, eur, or another cryptocurrency)
{action} specifies the type of data you want

Available Actions

Action	Description
`ticker`	Returns current price, volume, and market cap
`orderbook`	Provides buy/sell orders from exchanges
`trades`	Lists recent trades (price, volume, timestamp)
`candles`	Delivers OHLC (Open, High, Low, Close) candlestick data

For example, to get the latest Bitcoin price in US dollars:

https://api.cryptonator.com/api/btc-usd/ticker

This returns a clean JSON object containing:

{
  "ticker": {
    "base": "BTC",
    "target": "USD",
    "price": "43560.21",
    "volume": "48291.33",
    "change": "-120.45"
  },
  "timestamp": 1715000000,
  "success": true
}

You can replace ticker with orderbook, trades, or candles depending on your needs.

Practical JavaScript Examples

Integrating the Cryptonator API into your application takes just a few lines of code. Below are working examples using modern JavaScript (fetch) to retrieve different types of data.

1. Fetch Current Ticker Data

const url = 'https://api.cryptonator.com/api/eth-usd/ticker';

fetch(url)
  .then(response => response.json())
  .then(data => {
    if (data.success) {
      console.log(`Current ETH Price: $${data.ticker.price}`);
      console.log(`24h Volume: $${data.ticker.volume}`);
    } else {
      console.error('Failed to retrieve data');
    }
  })
  .catch(error => console.error('Error:', error));

This script logs Ethereum’s current USD price and trading volume directly to the console—ideal for embedding into live price trackers.

2. Retrieve Order Book Information

const url = 'https://api.cryptonator.com/api/btc-usd/orderbook';

fetch(url)
  .then(response => response.json())
  .then(data => {
    console.log('Buy Orders:', data.orderbook.bids.slice(0, 5)); // Top 5 bids
    console.log('Sell Orders:', data.orderbook.asks.slice(0, 5)); // Top 5 asks
  })
  .catch(error => console.error('Error:', error));

This retrieves the top buy and sell orders, useful for understanding market depth and liquidity.

3. Access Recent Trade History

const url = 'https://api.cryptonator.com/api/litecoin-usd/trades';

fetch(url)
  .then(response => response.json())
  .then(data => {
    data.trades.forEach(trade => {
      console.log(`${trade.type.toUpperCase()} @ $${trade.price} | ${trade.amount} LTC`);
    });
  })
  .catch(error => console.error('Error:', error));

This displays recent Litecoin trades, showing direction (buy/sell), price, and volume—perfect for building real-time trade feeds.

Frequently Asked Questions (FAQ)

Is the Cryptonator API really free to use?

Yes. The Cryptonator API is completely free with no registration, API keys, or rate limits. You can make unlimited requests without providing personal information.

Does it support altcoins beyond Bitcoin and Ethereum?

Absolutely. The API supports over 5,000 cryptocurrencies, including Litecoin, Ripple (XRP), Dogecoin, Cardano (ADA), Solana (SOL), and many others. Just use the correct ticker symbol in your request.

Can I use the Cryptonator API in production apps?

While it’s reliable and widely used, the Cryptonator API does not offer an official SLA or enterprise support. For mission-critical applications, consider pairing it with a backup data source or upgrading to a premium service like OKX’s market data APIs.

What is the update frequency of ticker data?

Ticker information updates approximately every minute. For time-sensitive applications requiring sub-second precision, consider using WebSocket-based APIs instead.

Is there documentation available for all endpoints?

Yes. Full technical documentation—including response formats, error codes, and example payloads—is available directly through the API provider’s site. However, due to its simplicity, most developers find they can integrate it with minimal reference.

How reliable is historical data via the candles endpoint?

Historical OHLC data is aggregated from major exchanges but may lack granular detail compared to dedicated financial data platforms. For high-frequency trading analysis or academic research, supplement with more comprehensive sources.

Final Thoughts

The Cryptonator API is a powerful yet minimalist solution for accessing real-time and historical cryptocurrency data. Its zero-cost model, combined with easy integration via RESTful endpoints, makes it ideal for prototyping, educational projects, small-scale tools, and personal dashboards.
