Tesco UK API — Real-Time United Kingdom Grocery Data
Access Tesco UK's complete grocery catalog via the Pepesto API — live pricing in GBP, promotional prices, nutritional data, and availability from tesco.com, returned as clean JSON.
What Does the Tesco UK API Return?
Everything visible in the Tesco UK app and website, returned as clean JSON via a single REST call.
Tesco UK-specific: Promotional prices and multi-buy deals are captured in each daily refresh.
Why Use an API Instead of Building Your Own Tesco UK Integration?
Developers who have tried to build their own Tesco UK data pipeline know the obstacles. Unofficial workarounds exist, but they come with real costs.
Tesco UK updates their website regularly — changing markup, adding rate limiting, or restructuring categories. Pepesto absorbs all of that. Your integration keeps working.
The same JSON field names work whether you're calling Tesco UK, Albert Heijn, Tesco, or any other supported chain. One integration for all of Europe.
Calling a REST API takes hours. Building, maintaining, and scaling your own Tesco UK data extraction takes months — and requires ongoing engineering resources.
DIY data extraction is fragile: a single layout change can silently break your pipeline. Pepesto monitors and updates integrations continuously so you don't have to.

Coverage & Data Freshness
Covers tesco.com — Tesco's UK online grocery store serving England, Wales, Scotland, and Northern Ireland. This is the UK storefront only. Tesco Ireland (tesco.ie) is a separate integration with its own catalog and pricing.
United Kingdom — tesco.com. Pricing in GBP.
Daily. Promotional prices and weekly deals are included in every update cycle.
All products listed online at tesco.com — including active promotions and full product details.
All product data and pricing is sourced from publicly listed pages on tesco.com. Pepesto does not access retailer-gated pricing or any data not visible to a regular visitor. Products shown at a lower price due to a promotion or budget-tier range are included because they appear publicly on the site — not through any special retailer agreement.
