On my machine, curl works but fetch only works in the browser - not on Node.js (v19).

It’s not the IP, or the request content/headers, nor the User-Agent. Akamai is fingerprinting and blocking these HTTPS requests to MEXC based on your TLS ciphers. Explanation here, but I agree that MEXC should fix this.

Until then, just reorder your TLS ciphers at the start of your program. Fixed it for me.

const tls = require('tls');
tls.DEFAULT_CIPHERS = 'TLS_AES_256_GCM_SHA384:ECDHE-RSA-AES256-GCM-SHA384';
tls.DEFAULT_MIN_VERSION = 'TLSv1.2';

fetch('https://www.mexc.com/open/api/v2/market/coin/list')
  .then(res => res.json())
  .then(console.log); // Works now!
