# E-commerce Competitor Price Monitor

Automatically track competitor product prices across Shopee, Lazada, Amazon, and other platforms. Get notified on price drops, generate weekly comparison reports, and make data-driven pricing decisions.

## Quick Start

1. **Configure targets**: Tell the agent your competitor product URLs and tracking frequency.
2. **Run a scan**: `scan prices now` — the agent visits each URL, extracts the price, and logs it.
3. **Get a report**: `price report` or `compare prices` — generates a clean comparison table.
4. **Set alerts**: `alert me when [product] drops below [price]` — the agent checks on schedule and notifies you.

## Workflow

### Step 1: Add Products to Track

Tell the agent in natural language:

> "Track the price of this Shopee product: https://shopee.com.my/... every 6 hours"
> "Add this Lazada link to my price monitor: https://www.lazada.com.my/..."
> "Monitor these 5 Amazon products daily"

The agent should:
- Accept any e-commerce product URL
- Ask for the desired check frequency (default: 24h)
- Ask for an optional target/alert price
- Store the config in `scripts/prices.json`

### Step 2: Price Scanning

When the user asks to scan or on schedule, the agent:

1. Reads the product list from `scripts/prices.json`
2. For each URL:
   - Visits the page using web browser
   - Extracts: product name, current price, currency, stock status, seller name
   - Handles platform-specific page structures (see [PLATFORMS.md](references/PLATFORMS.md))
3. Logs results to `scripts/price_history.jsonl` (append-only)
4. Updates latest prices in `scripts/prices.json`
5. Checks alert conditions — if triggered, notifies the user

### Step 3: Reports

On request, generate:

**Quick comparison** (inline Telegram-friendly):
```
📊 Price Watch — 3 products tracked
───────────────────────────────
Product A  → RM 89.90  ▼ 5% from last week
Product B  → RM 245.00  ▲ 2% (new all-time high)
Product C  → RM 59.90  — No change
```

**Detailed CSV report**: Run the Python script `scripts/report.py` to generate `reports/price_report_YYYY-MM-DD.csv` with full history.

### Step 4: Alerts

The agent supports natural language alert setup:

> "Tell me if iPhone 15 drops below RM 4,000"
> "Alert me when Product C goes on sale"
> "Notify me if any tracked product drops more than 15%"
> "Stop alerting me about Product A"

Alerts are stored in `scripts/alerts.json`. The agent checks them after each scan cycle.

## Scripts

### `scripts/manage.py` — Data management CLI

```bash
python3 scripts/manage.py products add <url> --name "Product Name" --interval 6 --alert-price 89.90
python3 scripts/manage.py products list
python3 scripts/manage.py products remove <id>
python3 scripts/manage.py alerts add --product <id> --type below --value 100.00
python3 scripts/manage.py alerts list
python3 scripts/manage.py alerts remove <id>
python3 scripts/manage.py history export --days 30
```

### `scripts/report.py` — Generate reports

```bash
python3 scripts/report.py                    # Quick summary (stdout)
python3 scripts/report.py --csv              # Full CSV to reports/
python3 scripts/report.py --product <id>     # Single product history
python3 scripts/report.py --trends           # Price trend analysis
```

## References

- **Platform scraping notes**: See [references/PLATFORMS.md](references/PLATFORMS.md) for platform-specific tips (Shopee dynamic loading, Lazada anti-scrape, Amazon structure)
- **Configuration**: See [references/CONFIG.md](references/CONFIG.md) for advanced setup (custom intervals, notification channels, export formats)

## Tips for Best Results

- **Shopee**: Page loads dynamically. Wait for `.product-price` or `[data-testid="product-price"]` elements.
- **Lazada**: May show region-specific prices. Check URL for `.my` (Malaysia), `.sg` (Singapore), etc.
- **Amazon**: Product prices are in `#corePriceDisplay_desktop_feature_div .a-price-whole`. Watch for coupon discounts listed separately.
- **Frequency**: For fast-moving products (electronics), check every 6h. For stable goods (household), daily is fine.
- **Freshness**: Always verify the extracted price looks reasonable before logging (reject nulls, zeroes, or parsing errors).
