How to remove the HTTP headers from a REST api call in Javascript

Hi i am trying to isolate the part of the response in the {}. It calls from the gemini public database and i am trying to get only the part in the curly braces to save it as a string in a database.

const gemini = async() =>{
    var burl = 'https://api.sandbox.gemini.com'
    var query = '/v1/pubticker/'+'ethusd'
    var url = burl + query
    var smth = fetch(url)
    delete smth.vary
    return smth

}

export default gemini

Here is the response i get

status: 200 OK
    content-length: 133
    content-type: application/json
    date: Mon, 08 Nov 2021 18:03:09 GMT
    server: nginx
    vary: Origin

{"bid":"4786.52","ask":"4787.78","volume":{"ETH":"8232.886562","USD":"38693689.50955448","timestamp":1636394400000},"last":"4786.83"}

This is what i want to isolate

{"ETH":"8232.886562","USD":"38693689.50955448","timestamp":1636394400000},"last":"4786.83"}

You don't need to "remove the headers". Just get the JSON response and use the data you need from that response. Your gemini function returns a Promise from a fetch call. You'd use that Promise like any other fetch call. For example:

let response = await gemini();
let result = await response.json();

Then result contains the object specified by the JSON data. From the description in the question it sounds like you specifically want the volume and last properties on that object.
