Promart Peru — product search & price scraper

Search Promart Peru's home-improvement catalog (Hogar y Construcción) for structured prices in PEN — tools, materials, fixtures and appliances with stock and product URLs.

🇵🇪 Peru · storefront: www.promart.pe · prices in PEN (PE)

Every run returns normalized product records — name, brand, current and list price in PEN, per-kilogram price, stock level, product and image URLs — ready for datasets, spreadsheets or dashboards. Fast, structured results: no manual copy-paste.

Use cases

• DIY & materials price watch — tools, hardware, paint, plumbing across Promart's catalog.
• Apartment setup shopping — track fixtures, shelving and appliances; catch listPrice drops before buying.
• Construction cost estimation — structured unit data for materials take-off sheets.
• Cross-brand comparison — pair with Oechsle (department store) for household goods coverage.

What it returns

• productKey — stable unique product ID for this store; join and dedupe on this, never the bare id
• name / brand — product display name and brand
• price / listPrice / currency — current and list price; the currency for this store is always PEN
• unitMultiplier / measurementUnit — pack size (a 5 kg bag → multiplier 5, unit kg)
• pricePerKg — normalized per-kilogram price when the weight is known, null otherwise
• availableQuantity / inStock — stock count (99999 means effectively unlimited) and availability flag
• url / imageUrl — product page and product image
• store / searchQuery / categoryResolved — run provenance: store slug, the query used, and whether the optional category filter resolved

Input

• search — free-text product search, e.g. arroz; defaults to a starter search when omitted
• category — optional; free-text category to scope the search against the store's own category tree (e.g. huevos)
• maxPages — 1–5 result pages (default 1; 24 products per page)
• maxResults — cap on returned products (default 50, max 200)
• requestDelaySecs — politeness delay between result pages (default 1.0 s)

This record always searches www.promart.pe — no store selection is needed (or offered); every record of this family is fixed to one storefront.

Quirks

1. Assortment spans tools→furniture; ambiguous terms benefit from a category hint (e.g. "herramientas").
2. Unit fields matter for materials (liters of paint, meters of cable) — use measurementUnit/unitMultiplier.
3. Sibling Intercorp banner Oechsle shares the platform but not the catalog.
