Yahoo Finance Api V8 Example Google App Script

Code.gs

function yahooF(ticker) {
  const url = `https://query1.finance.yahoo.com/v8/finance/chart/${ticker}`;
  
  const res = UrlFetchApp.fetch(url, {muteHttpExceptions: true});  
  const contentText = res.getContentText();
  const data = JSON.parse(contentText);
 
  // Check if the result exists and has data
  if (data && data.chart && data.chart.result && data.chart.result.length > 0) {
    const regularMarketPrice = data.chart.result[0].meta.regularMarketPrice;
    console.log(regularMarketPrice);
    return regularMarketPrice;
  } else {
    console.log("Error: Unable to retrieve market price.");
    return null;
  }
}

Thanks for getting back. That's a bummer that this field is not available via the API. Previously I and many others were using a regex pattern to grab various fields and it suddenly broke. I think going forward the API implementation is much more reliable, here's hoping they'll add more fields if enough people request.

Thanks for this updated function. It used to run great, but lately it gives this error many many times:
SyntaxError: Unexpected token 'E', "Edge: Not Found" is not valid JSON
in this line:
const data = JSON.parse(contentText);

It seems like yahoo are fighting against this script.

Same problem here. As a workaround I replaced the line

const data = JSON.parse(contentText);

by this block of code:

data = null;
try {
data = JSON.parse(contentText);
} catch (error) {
return yahooF(ticker)
}

So basically that makes the function recursive until the JSON.parse succeeds.
