Err 404 when buy,sell, etc..

I’m using local server on a Chrome browser to run the following code:

` const binance = require(‘./node-binance-api.js’);

binance.options({ APIKEY: ‘MY-API-KEY’, APISECRET: ‘*MY-SECRET-API’, useServerTime: false, // If you get timestamp errors, synchronize to server time at startup test: true // If you want to use sandbox mode where orders are simulated });

binance.prices(‘ETHBTC’, (error, ticker) => { console.log("Price of ETHBTC: ", ticker.ETHBTC); });

var quantity = 0.05 ; binance.marketBuy(“ETHBTC”, quantity); `

I’ve gotten the binance.prices to work using this wrapper, however, whenever there is a more secure network is needed, which involve my API-key or Secret-Key, i cannot seem to retrieve information.

My assumptions for this possibility:

1. Chrome browser is not supported by binance api server
2. My API-Key/Secret-Key are banned from binance api
3. Code is not primed for more secure options

Let me know what you think. Thanks in advance!

I’ve tried CORS browser extension to bypass some preflights with allow orgin headers, however, this only worked for “GET” functions. As soon as I attempted “POST”, I’ve tried adding headers that were shown in public api but this only resulted in errors of 400, 401, 404.

I am convinced you’re right, and I’m going to attempt server-side (if possible) rather than client-side.

Thank you for your answer. I might be back with an update on my situation.

I think people have had some success with electron, turning it into a desktop app https://electronjs.org But I haven’t tested it for that
