83We didn't. We left them where they are, and proxy to them.
84
85Writing a proxy in Val Town (or any functions platform with the ['fetch handler' interface](https://blog.val.town/blog/the-api-we-forgot-to-name/)) is a delight:
86
87```ts

3import { createRoot } from "https://esm.sh/react-dom@18.2.0/client";
4
5// Google Sheets API Configuration
6// Note: You'll need to set up Google Cloud Project and enable Sheets API
7// Replace with your actual credentials in a real-world scenario
8const SHEET_ID = "1seOqUubZTebHow5wpTLl411HRmsrG_fxugu3j2rNRdg";
9const API_KEY = "DEMO_KEY"; // Replace with actual API key
10
11function SubmissionNotice({ message, onClose }) {
96      ];
97
98      const response = await fetch(`https://sheets.googleapis.com/v4/spreadsheets/${SHEET_ID}/values/AllSubmissions!A:H:append`, {
99        method: 'POST',
100        headers: {
101          'Authorization': `Bearer ${API_KEY}`,
102          'Content-Type': 'application/json'
103        },

31Refer to [Twitter's search operators](https://socialdata.gitbook.io/docs/twitter-tweets/retrieve-search-results-by-keyword#endpoint-parameters) to fine-tune your query.
32
33### 4. Test API call
34Set `isProd = false` in the code if you are testing, to ensure there are enough tweets to display. <br>
35Toggle it back to `true` when you're ready to run this cron job in production and actuall send notifications.
60
61### NOTE: Usage Limits
62This val uses the SocialData API for Twitter data:
63
64- **Proxies via Val Town's [SocialDataProxy](https://www.val.town/v/stevekrouse/socialDataProxy)**: Limited to 10 cents per day for [**Val Town Pro users**](https://www.val.town/pricing). This API is *only* for Pro users.
65- **Need more calls?** Sign up for your own [SocialData API token](https://socialdata.tools) and configure the [`socialDataSearch`](https://www.val.town/v/stevekrouse/socialDataSearch) function.

199    for (const chunk of chunks) {
200      await bot.api.sendMessage(chatId, chunk, { parse_mode: "Markdown" });
201      // Store each chunk in chat history
202      await storeChatMessage(

53You'll need to set up some environment variables to make it run.
54
55- `ANTHROPIC_API_KEY` for LLM calls
56- You'll need to follow [these instructions](https://docs.val.town/integrations/telegram/) to make a telegram bot, and set `TELEGRAM_TOKEN`. You'll also need to get a `TELEGRAM_CHAT_ID` in order to have the bot remember chat contents.
57- For the Google Calendar integration you'll need `GOOGLE_CALENDAR_ACCOUNT_ID` and `GOOGLE_CALENDAR_CALENDAR_ID`. See [these instuctions](https://www.val.town/v/stevekrouse/pipedream) for details.

8## Hono
9
10This app uses [Hono](https://hono.dev/) as the API framework. You can think of Hono as a replacement for [ExpressJS](https://expressjs.com/) that works in serverless environments like Val Town or Cloudflare Workers. If you come from Python or Ruby, Hono is also a lot like [Flask](https://github.com/pallets/flask) or [Sinatra](https://github.com/sinatra/sinatra), respectively.
11
12## Serving assets to the frontend
20### `index.html`
21
22The most complicated part of this backend API is serving index.html. In this app (like most apps) we serve it at the root, ie `GET /`. 
23
24We *bootstrap* `index.html` with some initial data from the server, so that it gets dynamically injected JSON data without having to make another round-trip request to the server to get that data on the frontend. This is a common pattern for client-side rendered apps.
25
26## CRUD API Routes
27
28This app has two CRUD API routes: for reading and inserting into the messages table. They both speak JSON, which is standard. They import their functions from `/backend/database/queries.ts`. These routes are called from the React app to refresh and update data.
29
30## Errors
31
32Hono and other API frameworks have a habit of swallowing up Errors. We turn off this default behavior by re-throwing errors, because we think most of the time you'll want to see the full stack trace instead of merely "Internal Server Error". You can customize how you want errors to appear.
