Insecure SSL Cert Fetch 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/ 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)

Proxied fetch - Docs ↗ The Javascript Fetch API is directly available within a Val. However sometimes fetch calls are blocked by the receiving server for using particular IP addresses. Additionally, network blips or unreliable web services may lead to failures if not handled properly. The Val Town standard library contains an alternative version, std/fetch , that wraps the JavaScript Fetch API to provide additional functionality. The fetch function from std/fetch reroutes requests using a proxy vendor so that requests obtain different IP addresses. It also automatically retries failed requests several times. Note that using std/fetch will be significantly slower than directly calling the Javascript Fetch API due to extra network hops. Usage After importing std/fetch , the fetch method is used with the same signature as the Javascript Fetch API. import { fetch } from "https://esm.town/v/std/fetch"; let result = await fetch("https://api64.ipify.org?format=json"); let json = await result.json(); console.log(json.ip); If you run the above code multiple times, you'll see that it returns different IP addresses, because std/fetch uses proxies so that each request is made from a different IP address. 📝 Edit docs
