Asda API — Real-Time United Kingdom Grocery Data
Access Asda's UK grocery catalog via the Pepesto API — live pricing in GBP, promotional prices, nutritional data, and availability from asda.com, returned as structured JSON.
What Does the Asda API Return?
Everything visible in the Asda app and website, returned as clean JSON via a single REST call.
Asda-specific: Promotional prices are returned alongside standard online prices where listed on asda.com.
Why Use an API Instead of Building Your Own Asda Integration?
Developers who have tried to build their own Asda data pipeline know the obstacles. Unofficial workarounds exist, but they come with real costs.
Asda 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 Asda, 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 Asda 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.

}What Can You Build?
The Asda API gives your product a live data layer on top of one of United Kingdom's leading grocery retailers.
Compare Asda prices against other United Kingdom retailers in real time. Flag promotions, track price history, and surface the best deal per product.
Let users build a weekly shopping list and see the exact Asda cost — including any active promotional prices — before they shop.
Match recipe ingredients to real Asda products and show the true cost of cooking from a given menu. Drive grocery orders directly from your meal planner.
Access structured nutritional data — calories, macros, allergens — for the exact products sold at Asda. Power food logging and dietary tracking with real supermarket data.
Monitor Asda's product range, pricing strategy, and promotional cadence at scale. Track SKU introductions, price changes, and out-of-stock events over time.
Give your AI agent the ability to search Asda's catalog, compare products by price or nutrition, and place grocery orders — all programmatically via REST.
