# Pricing Tracker

## Mission
Collecter prix actuel et disponibilité depuis multiples retailers (Amazon, sites spécialisés selon catégorie).

## Outils de Scraping

### Priorité 1: MCP Apify (Recommandé)
| Outil | Usage |
|-------|-------|
| `mcp__apify__call-actor` avec `apify/amazon-product-scraper` | Prix Amazon structuré (inclut prix, stock, shipping) |
| `mcp__apify__apify-slash-rag-web-browser` | Prix autres retailers (Decathlon, Darty, etc.) |

### Priorité 2: Fallback
| Outil | Usage |
|-------|-------|
| `WebFetch` | Si MCP échoue ou timeout (>2 min) |

**Avantages MCP Apify**:
- Amazon: Prix exact, stock, shipping en JSON structuré
- RAG Browser: Recherche + extraction prix en une seule requête

## Quick Summary
1. **Amazon**: MCP `apify/amazon-product-scraper` (ou WebFetch fallback)
2. **Autres retailers**: MCP `rag-web-browser` (ou WebFetch fallback)
3. Extract: prix, disponibilité, shipping, promos actives
4. Save comparison table JSON + cache 7j

## Inputs
- **product_name**: Nom produit
- **category**: Catégorie (pour sélectionner retailers appropriés)
- **amazon_url**: URL Amazon (optionnel)

## Outputs
- `pricing.json`: Tableau prix par retailer
- Cache 7j

## Dependencies
- data/category_specs.yaml (retailers par catégorie)
- Load `helpers/retailers.yaml` when scraping for patterns

## Workflow

### 1. Load retailers
```javascript
retailers = category_specs.yaml[category].retailers
// Example velo: ["decathlon.fr", "alltricks.fr", "probikeshop.fr"]
```

### 2. Scrape Amazon (if in retailers)
```javascript
**PRIMARY: MCP Apify**
mcp__apify__call-actor({
  actor: "apify/amazon-product-scraper",
  step: "call",
  input: {
    categoryOrProductUrls: [amazon_url],
    maxItems: 1
  }
})

mcp__apify__get-actor-output({
  datasetId: result.datasetId,
  fields: "title,price,availability,delivery"
})
→ Returns: { price: 549, availability: "In Stock", delivery: "Livraison gratuite" }

**FALLBACK: WebFetch** (if MCP fails)
WebFetch product page + extract with retailers.yaml selectors
```

### 3. Scrape other retailers (2-3)
```javascript
For each retailer:
  query = "{product_name} prix site:{retailer}"

  **PRIMARY: MCP Apify RAG Web Browser**
  mcp__apify__apify-slash-rag-web-browser({
    query: query,
    maxResults: 1,
    outputFormats: ["markdown"]
  })

  Parse Markdown:
  "Extract pricing information:
   - Current price (number only)
   - Stock availability
   - Shipping cost
   - Active promotions
   Return as JSON."

  **FALLBACK: WebFetch**
  WebFetch product page + extract with retailers.yaml selectors
```

### 4. Build comparison table
```javascript
{
  "product": product_name,
  "timestamp": now,
  "retailers": [
    {
      "name": "Amazon",
      "price": 549,
      "availability": "in_stock",
      "shipping": "Gratuit",
      "promo": null
    },
    {
      "name": "Decathlon",
      "price": 549,
      "availability": "in_stock",
      "shipping": "Gratuit en magasin",
      "promo": "-10% membres"
    }
  ],
  "best_price": 494.10,  // Decathlon with promo
  "best_retailer": "Decathlon"
}
```

### 5. Save + cache
- Save: `data/research_{timestamp}/{product}/pricing.json`
- Cache: `data/cache/pricing/{cache_key}.json` (7j TTL)

## Error Handling
- Retailer unavailable → Skip, continue with others
- Price not found → Mark as "N/A"
- Out of stock → Mark availability = false
- MCP timeout → Fallback to WebFetch automatically
