+# Revault - The Autonomous Watchdog for Resellers
+
+A 24/7 price watchdog powered by [TinyFish](https://tinyfish.ai) browser agents. Add items you want to flip, set your target margin and max buy price, and ResaleRadar monitors reseller platforms every 5 minutes — alerting you on Discord the moment a deal hits your target.
+
+Built for the [TinyFish Take-Home Challenge] *"The Autonomous Watchdog"*
+
+## How It Works
+
+1. **Add an item** to your Watchdog List (e.g., "Louis Vuitton Neverfull MM")
+2. **Set your target** — max buy price + target margin %
+3. **TinyFish agents** scrape reseller platforms every 15 minutes
+4. **Discord alert** fires instantly when a listing meets your criteria and then after every 15 minutes.
+
+## Categories Supported
+
+| Category | Platforms Scraped |
+|----------|-------------------|
+| Watches | Chrono24, WatchBox, Bob's Watches, eBay |
+| Bags | Fashionphile, Vestiaire, Rebag, GoogleShopping |
+| Trading Cards | TCGPlayer, eBay, StockX, PWCC |
+| Sports & Fan Gear | Fanatics, eBay Sports, PWCC, Goldin, StockX, SidelineSwap |
+| Sneakers | StockX, GOAT, eBay, Alias |
+
+## Setup — Run Your Own Instance
+
+### 1. Clone and install
+
+```bash
+git clone <your-repo-url>
+cd revault-reseller-watchdog
+npm install
+```
+
+### 2. Get your API keys
+
+- **TinyFish API Key**: Sign up at [tinyfish.ai](https://tinyfish.ai), go to Dashboard → Settings → API Keys
+- **Discord Webhook URL**: In your Discord server, go to Server Settings → Integrations → Webhooks → New Webhook → Copy URL
+
+### 3. Configure
+
+Create a `.env` file in the project root:
+
+```env
+VITE_TINYFISH_API_KEY=sk-tinyfish-your-key-here
+VITE_DISCORD_WEBHOOK_URL=https://discord.com/api/webhooks/your-webhook-here
+```
+
+Or edit `src/config.js` directly with your keys.
+
+### 4. Run locally
+
+```bash
+npm run dev
+```
+
+### 5. Deploy 
+
+
+Set the environment variables in Vercel Dashboard → Project Settings → Environment Variables.
+
+## Architecture
+
+```
+User adds item → TinyFish browser agents scrape reseller sites
+                         ↓
+              Extract: price, condition, listing URL
+                         ↓
+              Compare to user's max buy price + target margin
+                         ↓
+              If target hit → Discord webhook alert
+              If not → update watchlist, check again in 5 min
+```
+
+## Tech Stack
+
+- **Frontend**: React + Vite
+- **Scraping**: TinyFish Web Agent API (handles anti-bot, JS-heavy sites)
+- **Notifications**: Discord Webhooks
+- **Hosting**: Vercel
