All four major Irish supermarkets: Aldi Ireland, Tesco Ireland, SuperValu and Dunnes Stores. The full catalogue is refreshed every night across all four retailers.
The full catalogue snapshot is rebuilt every night. Every row carries a snapshot date so customers know exactly when each price was captured.
Tesco Clubcard prices are captured per SKU in a dedicated field, separate from shelf price. SuperValu and Dunnes do not expose a comparable member-only price, so their promotional pricing is captured through the was-price and offer-text fields instead. Shelf moves, promotions and loyalty pricing are kept as separate signals throughout, so an expiring offer is never mistaken for a shelf-price change.
Yes. Barcodes are returned by default on the catalogue endpoints: roughly 96% coverage for Tesco, 98% for SuperValu, 100% for Dunnes and 69% for Aldi. Aldi is the awkward one. It publishes no codes in its catalogue, so its coverage was near zero until we resolved its own-label range against Aldi's own barcode lookup, which confirms which code belongs to which Aldi product. One caveat worth stating plainly: those are Aldi own-brand codes, and nobody else sells Aldi own-brand, so they give you a stable identity for the product and a key into outside data, but they do not line an Aldi product up against a Tesco one. Cross-retailer matching for Aldi still leans on brand, name and pack size. For the other three retailers, barcodes are what drive our matching, so the same product can be compared on identity rather than on name similarity.
Yes. Endpoints accept an on=YYYY-MM-DD parameter to return catalogues, promotions or price changes as they stood on that date.
Yes. Dashboard subscribers can connect through Power Query, load refreshable tables and reference products with formulas such as XLOOKUP and FILTER.
Yes. The Dashboard subscription is all-inclusive: it carries direct JSON API access and the Weekly Briefing as standard. The Briefing is part of the Dashboard, not a separate product. API-only and metered usage-based access are also available if you do not need the dashboard surfaces.
A weekly grocery price intelligence briefing covering shelf inflation, promotion movement, top SKU movers and category changes. It is included with the Dashboard subscription.
Book a demo and we will size access to what you actually need: the full Dashboard including API access and the Weekly Briefing, API-only access, or metered usage-based pricing for lighter integrations. Custom historical exports are quoted separately. Our public Apify actor returns a capped 100-row sample if you want to see the data shape before talking to us.
BasketWatch tracks grocery prices across Tesco, Dunnes Stores, SuperValu and Aldi every day and keeps each day as a snapshot. You can follow a single product, a brand or a whole category over time through the dashboard, a CSV export or the JSON API.
Every product is re-checked daily, so BasketWatch shows grocery price increases and decreases the day after they happen, kept separate from promotions and member prices so a genuine shelf-price rise is never masked by an expiring offer.
Every nightly snapshot is retained from launch in May 2026 onward, building a historical grocery price record for Ireland. Add on=YYYY-MM-DD to any endpoint to see prices as they stood on a given date, or export the full price history for analysis in Excel, Power BI or your own models.
