Get notified whenever you, your company, or topics of interest are mentioned online.\n\nBuilt with [Browserbase](http://browserbase.com). Inspired by [f5bot.com](http://f5bot.com).\n\nFull code [tutorial](https://www.browserbase.com/blog).\n\n## Getting Started\nTo run Slack Scout, you’ll need a \n- Browserbase API key \n- Slack Webhook URL: setup [here](https://docs.val.town/integrations/slack/send-messages-to-slack/)\n- Twitter Developer API key\n\n### Browserbase\n\n[Browserbase](https://www.browserbase.com/) is a developer platform to run, manage, and monitor headless browsers at scale. We’ll use Browserbase to navigate to, and scrape our different news sources. We’ll also use [Browserbase’s Proxies](https://docs.browserbase.com/features/stealth-mode#proxies-and-residential-ips) to ensure we simulate authentic user interactions across multiple [browser sessions](https://docs.browserbase.com/features/sessions).\n\nGet started with Browserbase for free [here](https://www.browserbase.com/sign-up).\n\n### Twitter\n\nWe’ve decided to use the Twitter API to include Twitter post results. It costs $100 / month to have a Basic Twitter Developer account. _If you decide to use Browserbase, we can lend our token. Comment below for access._\n\nOnce you have the `SLACK_WEBHOOK_URL`, `BROWSERBASE_API_KEY`, and `TWITTER_BEARER_TOKEN`, input all of these as [Val Town Environment
