This will be useful if you're getting a invalid peer certificate: UnknownIssuer error.

If you need to make a fetch request to a website with a dubious or non-standard SSL certificate, you can use this proxy we made on Cloudflare workers (which doesn't verify SSL certs): https://unsecure-fetch.val-town.workers.dev/

Create val
import { insecureFetch } from "https://esm.town/v/stevekrouse/insecureFetch";

const url = "https://assignment-api.uspto.gov/patent/basicSearch?query=1234567&fields=main&rows=20";
const data = await insecureFetch(url)
const text = await data.text();
console.log(text)
