have this bit of code in a chrome extension background.js file, it should only run when a button is clicked that I'm loading onto the page using contentScript.js in the service worker I only see 4 API calls per button press (there are two videos on the page), there's no way I'm using this more than 500 times let alone 10,000 per day yet i'm reaching the quota limit. Any ideas?

chrome.runtime.onMessage.addListener((request, sender, sendResponse) => {
    if (request.type === 'SEARCH_YOUTUBE') {
    const title = request.title;
    console.log('about to call searchyoutube w/ title: ' + title);
    searchYouTube(title)
      .then(viewCount => {
        sendResponse({ viewCount });
      })
      .catch(err => {
        console.error('Error searching YouTube:', err);
        sendResponse({ viewCount: null });
      });
    return true; // Keep the message channel open for async response
  }
});

    }

    const videoItem = searchData.items[0];

function decodeHtml(html) {
    const entities = {
      '&': '&',
      '&lt;': '<',
      '&gt;': '>',
      '&quot;': '"',
      '&#39;': "'"
      // Add more entities as needed
    };
  
    return html.replace(/&[a-zA-Z0-9#]+;/g, (match) => entities[match] || match);
  }

as per quota cost page Search list costs 100 quota points.

Math

10000 / 100 = 100

That means that you can make max 100 calls per day. The quota resets at mid night west cost USA time. Being that your using javascript even a refresh of the page is going to rerun the calls.

Remember this is 10k is the development quota. You can request an extension.
