Cal Hits Bot

A Bluesky bot that posts whenever Seattle Mariners catcher Cal Raleigh gets a hit during a game.

The bot runs as a Val.town scheduled function every 5–10 minutes. It:

1. Checks the MLB Stats API for a live or completed Mariners game
2. Reads Cal Raleigh's batting stats from the boxscore
3. Posts to Bluesky if a new hit or home run has occurred since the last check
4. Persists hit state in Val.town blob storage to avoid duplicate posts

Home runs get special treatment — the bot fetches the season HR count and posts with extra flair.

• Runtime: Val.town (serverless, cron-scheduled)
• Bluesky: @atproto/api
• Data: MLB Stats API (free, public, no auth required)
• State: Val.town blob storage

Create an App Password in your Bluesky account settings (Settings → Privacy and Security → App Passwords). Do not use your main account password.

1. Create a new Val at val.town
2. Paste in the contents of cal-hits-bot.js
3. Add environment variables:
   • BLUESKY_HANDLE — your Bluesky handle (e.g. yourbot.bsky.social)
   • BLUESKY_PASSWORD — the App Password you created
4. Set the Val type to Cron with schedule */5 * * * * (or whatever)

That's it. Val.town handles execution, logging, and storage.

npm install
BLUESKY_HANDLE=your.handle.bsky.social BLUESKY_PASSWORD=your_app_password node cal-hits-bot.js

Change the player ID constant at the top of cal-hits-bot.js. You can look up any player's ID from the MLB Stats API:

https://statsapi.mlb.com/api/v1/people/search?names=FirstName+LastName

You'll also want to update the team ID used for schedule lookups and the hashtags in the post template.
