How to use API endpoint for coin data on a website?
I'm working on a website and I need to display the current market cap and price of our coin. I've found an API related to our coin, but I'm unsure how to use it. Could someone guide me on how I can get this information through the API?

2To display the current market cap and price, you need to use the API endpoint. As mentioned, the endpoint you should be looking at is below the getCoinByType
function. It seems like you might want to use the getCoinMetaData
endpoint to retrieve information about a single coin. Check the metadata returned from this endpoint to see if it includes the market cap and price.
If you want to show your coin’s current market cap and price on your website, and you already have access to an API for it, you can use JavaScript to fetch the data and display it on your page. First, check the API documentation to see the exact endpoint that returns the price and market cap. Most APIs (like CoinGecko or CoinMarketCap) have a URL you can call, and it returns data in JSON format.
Here's a simple example using JavaScript to fetch and show your coin's price and market cap:
<div id="price">Loading price...</div>
<div id="marketCap">Loading market cap...</div>
<script>
async function loadCoinData() {
try {
const response = await fetch('https://api.example.com/v1/coin/your-coin-id');
const data = await response.json();
// Example: adjust these keys based on your API's structure
const price = data.market_data.current_price.usd;
const marketCap = data.market_data.market_cap.usd;
document.getElementById('price').textContent = `Price: $${price}`;
document.getElementById('marketCap').textContent = `Market Cap: $${marketCap}`;
} catch (error) {
console.error('Failed to load coin data:', error);
}
}
loadCoinData();
</script>
Replace the fetch()
URL with your API's endpoint and adjust the keys (market_data
, current_price
, etc.) to match the structure of the response.
Make sure your API allows public access (or use an API key if needed). Also, consider caching the result or limiting the frequency of API calls to avoid hitting rate limits.
For more guidance, if you're using CoinGecko, their API documentation is at: https://www.coingecko.com/en/api
This method lets you keep your site’s coin info updated in real time with just a few lines of code.
