3Here's an example using the [Hono](https://hono.dev/) server library with the [Web API](https://docs.val.town/api/web). It works great!

1# Proxied fetch - [Docs ↗](https://docs.val.town/std/fetch)
2
3The Javascript [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/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.
4
5The Val Town standard library contains an alternative version, [`std/fetch`](https://www.val.town/v/std/fetch), that wraps the JavaScript Fetch API to provide additional functionality. The fetch function from [`std/fetch`](https://www.val.town/v/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`](https://www.val.town/v/std/fetch) will be significantly slower than directly calling the Javascript Fetch API due to extra network hops.

7## Usage
8
9After importing [`std/fetch`](https://www.val.town/v/std/fetch), the fetch method is used with the same signature as the Javascript Fetch API.
10
11```ts title="Example" val
12import { fetch } from "https://esm.town/v/std/fetch";
13
14let result = await fetch("https://api64.ipify.org?format=json");
15let json = await result.json();
16console.log(json.ip);

1returns image URL (and only image URL) for a given NFT contract + tokenId. Uses Alchemy's NFT API

3to this use val, copy the [Web API](https://docs.val.town/api/web) endpoint and use ?query params to specify the contract address and tokenId you want:

5<https://jamiedubs-nftimage.web.val.run/?contractAddress=0x3769c5700Da07Fe5b8eee86be97e061F961Ae340&tokenId=666> - FIXME valtown is turning & into "&amp;", you need to fix it. [even like this broken](https://jamiedubs-nftimage.web.val.run/?contractAddress=0x3769c5700Da07Fe5b8eee86be97e061F961Ae340&tokenId=666)

1use by copying web API endpoint and appending "?contractAddress=...&tokenId..."  - here's an example:

5uses [Alchemy](https://docs.alchemy.com/reference/getnftmetadata) for indexed NFT data, via my other [jamiedubs/alchemyClient val](https://www.val.town/v/jamiedubs/alchemyClient)

32Finally, you may be wondering why I queue up feedback in `@stevekrouse.docsFeedback`, a private JSON val, and then process it via [`@stevekrouse.formFeedbackAlert`](https://www.val.town/v/stevekrouse.formFeedbackAlert) instead of sending it along to Discord directly in this val. I [tried that originally](https://www.val.town/v/stevekrouse.docFeedbackForm?v=61) but it felt too slow to wait for the API call to Discord before returning the "Thanks for your feedback" message. This is where the `context.waitUntil` method (that Cloudflare workers and Vercel Edge Functions support) would really come in handy – those allow you to return a Response, and then continue to compute. Currently Val Town requires you to stop all compute with the returning of your Response, so the only way to compute afterwards is to queue it up for another val to take over, and that's what I'm doing here.
