Cloudflare Worker pricebot using Pyth Network oracle to update Discord bot nicknames with live price data.

How It Works

1. Cron Trigger - Runs every 1 minute
2. Fetches Price - Gets price from Pyth Hermes API
3. Formats - Dynamic decimal places (BTC: $50000, DOGE: $0.1500)
4. Updates - Sets bot nickname in all guilds the bot is in
5. Gateway Keepalive - Connects to Discord gateway and stays connected for ~59 seconds to keep bot "online" between cron triggers

Setup

1. Create Discord Bot

1. Go to Discord Developer Portal
2. Create a new application
3. Go to Bot section
4. Click Reset Token to get your bot token
5. Enable Public Bot (for personal use)
6. Under Privileged Gateway Intents, enable:
   • Server Members Intent

2. Add Bot to Server

Generate OAuth2 URL with bot scope:

https://discord.com/oauth2/authorize?client_id=YOUR_CLIENT_ID&scope=bot&permissions=1

Visit that URL to add the bot to your server(s).

3. Get Pyth Feed ID

Find the price feed ID for your desired asset at Pyth Network Price Feeds.

Example feed IDs:

• BTC: 0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43
• ETH: 0xff6147a7b6429c8f3f3e9d0da9a6e7f6c6e6e6e6e6e6e6e6e6e6e6e6e6e6e6e6

4. Create GitHub Repository

Push this code to a new GitHub repository.

5. Connect to Cloudflare Workers

1. Go to Cloudflare Dashboard
2. Navigate to Workers & Pages
3. Click Create application → Import a Worker project from GitHub
4. Connect your GitHub repo (root directory)

6. Configure Secrets

In Cloudflare Workers dashboard, go to your worker → Settings → Variables:

Add the following secrets via wrangler secret put:

# Via Wrangler CLI
wrangler secret put DISCORD_BOT_TOKEN
wrangler secret put PYTH_FEED_ID
wrangler secret put TICKER

Or set via dashboard:

• DISCORD_BOT_TOKEN - Your Discord bot token
• PYTH_FEED_ID - Pyth price feed ID (e.g., 0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43)
• TICKER - Ticker symbol (e.g., BTC, ETH, SOL)

7. Deploy

Once secrets are configured, Cloudflare will auto-deploy on push to main branch.

Or manually deploy:

npm install
npm run deploy
