Mercadona Scraper – Products, Prices, EAN & Price History

Scrape the full Mercadona online catalog (about 4,000 products) in ~15 seconds, for any Spanish postal code. Get prices, price per kg / litre, packaging, categories, Hacendado (private label) flag, price drops and new arrivals – and optionally the EAN barcode, brand, origin, suppliers, ingredients and allergens of every product.

Run it daily and it tracks price changes for you: every product gets the price of the previous run, the change in EUR and %, and a webhook can ping Slack / Zapier / Make / n8n when prices move.

Extrae el catálogo completo de Mercadona (supermercado online) por código postal: precios, precio por kilo/litro, marca Hacendado, bajadas de precio, novedades, EAN, proveedores, ingredientes y alérgenos, con histórico de precios.

Why this Mercadona scraper?

• ⚡ Fast and light – talks to the same JSON API as tienda.mercadona.es. No browser, no proxies, no login. A full catalog costs a fraction of a compute unit.
• 📍 Real regional prices – each postal code is mapped to the warehouse that serves it. Prices and assortment differ between Madrid, Barcelona, Valencia, Sevilla, the Balearic and the Canary Islands (no VAT there!). Pass several postal codes in one run to compare regions.
• 🏷️ EAN + suppliers – find out who manufactures each Hacendado / Deliplus / Bosque Verde product, get the barcode to match against other retailers, and read ingredients and allergens.
• 📉 Price tracking built in – no database needed on your side: the actor remembers the previous prices and flags priceChange, priceChangePct, newSinceLastRun. Turn on Output only changed or new products for a tiny daily diff.
• 💸 Cheap, transparent pay-per-event pricing – you only pay for the products you get.

Use cases
