Display Data from fetch api

Question

Hi i want to fetch data from avascan api and display it in html, but i am not able to do this. I have tried fetch api, json and ajax ways but none worked for me. Any suggestions? This is my html https://avascan.info/api/v1/home/statistics

const api_url = 'https://avascan.info/api/v1/home/statistics';


async function getAVA() {
  const response = await fetch(api_url);
  const data = await response.json();
  const {
    blockchains,
    validators
  } = data;
  document.getElementById('lat').textContent = blockchains.toFixed(2);
  document.getElementById('lon').textContent = validators.toFixed(2);
}

getAVA();

setInterval(getAVA, 1000);

<h1>What the stats?</h1>

<p>
  blockchains: <span id="lat"></span>°<br /> validators: <span id="lon"></span>°
</p>

<div id="issMap"></div>

You are getting a CORS protection error, as mentioned before.

However it seems you need to use a GraphQL API: https://graphql.avascan.info/

Look at this quick example:

      async function getAVA() {

        fetch('https://graphql.avascan.info', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
            },
            body: JSON.stringify({
            query: `
            query {
                stats {
                    priceAvaxUsd,
                    connectedNodes
                }
            }`
            }),
            })
            .then((res) => res.json())
            .then((result) => console.log(result));
      }

      getAVA();
