Prices are set per store, so every call is answered for one Lucky store: give a ZIP code or a store_id from `stores` (without either, a fixed default store, Lucky Supermarkets - 767 near 94577, is used and the response says store_defaulted: true). `search` returns the site's own ranked results (cheese: 298 products at the default store), `category` lists a collection such as Milk, `offers` returns Weekly Ad, Member Prices, Sales, `product/detail` adds ingredients, warnings and images, `categories` lists the category tree and `stores` lists Lucky stores around a ZIP code with distance and services. The price matched the price printed on the shop.luckysupermarkets.com product page for 8 of 8 products we checked.
What a Lucky Supermarkets field actually contains
Fields that read differently from how they look, measured on live responses on 2026-10-18.
| Field | What it holds |
|---|---|
| price, price_display | The price at the chosen store as the shop.luckysupermarkets.com product page prints it (matched on 8/8 products, e.g. Sunnyside Farms Cage Free Eggs $3.99). |
| original_price, discount_percent | The struck-through regular price on sale items and the discount computed from the two prices; null when the item is not on sale. |
| promotions, buy_one_get_one | Deals shown on the item: BOGO, multi-buy ('Buy 2 for $9.16'), member offers. They are never folded into price. |
| loyalty_price | A separate card or member price when the site shows one next to the regular price; null otherwise. |
| store, store_defaulted | The Lucky store that priced the response (id, name, street, city). store_defaulted is true when you gave neither postal_code nor store_id. |
| unit_price_text | The unit price as the site prints it ("$0.03/fl oz"). For items sold by weight, price is the estimated package price and price_is_estimate is true. |
| stock_level, likely_out_of_stock | many_in_stock, in_stock, likely_out_of_stock or out_of_stock for that store. |
| matches_query | Whether the row shares a word with your search. The site fills a search that matches nothing with unrelated products; such pages are dropped and counted in unmatched_dropped. |
Prices differ between stores: the same 16 products cost differently on 2 of them at a store near 95112 on the same day.

Questions developers ask before integrating
Does Lucky Supermarkets have a public API?
No public product API. This API reads what shop.luckysupermarkets.com shows a logged-out visitor and returns it as JSON. No account is needed.
Why do I need a ZIP code?
Lucky prices are set per store. Pass postal_code or store_id; without them a fixed default store is used and store_defaulted is true.
Do delivery, pickup and in-store prices differ?
Not in our measurement: the store's delivery, pickup and in-store price lists were identical on 16 of 16 products, so one price is returned, the one the product page prints.
Can I get the Lucky Weekly Ad and Member Prices?
Yes. offers returns weekly_ad, member_prices or sales, each priced at one store. promotions lists the three with their product counts.
Is the member price in `price`?
No. price is the price the product page prints for every shopper; member deals appear as promotion labels in promotions[].
How do I find Lucky stores near a ZIP code?
Call stores with postal_code. Around 94577 it returned 45 stores, nearest first, with address, coordinates, distance in miles and the services each offers. Use a store_id in any other call to price at that store.
Does search return everything the site finds?
Yes, in the site's own order, 20 per page by default (up to 40). cheese returned 298 products. The site can re-rank its list between two calls, so reading by page number can repeat or skip a product; follow next_cursor from each answer for a complete scan: it never returns a product twice and fills the page from the rest of the list.
How fresh is the data?
Every call reads shop.luckysupermarkets.com live; nothing is cached on our side.
What is the Lucky Supermarkets API?
Lucky Supermarkets API is a ReefAPI endpoint group for shop.luckysupermarkets.com prices as json per store: search, categories, weekly ad, member prices, sales, product details and the store locator. It returns live JSON through POST requests under /lucky-supermarkets/v1.
Is the Lucky Supermarkets API free to try?
Yes. ReefAPI starts with 1,000 free credits, no card required. Lucky Supermarkets calls use the same shared credit balance as every other ReefAPI engine.
Do I need a Lucky Supermarkets login or account?
No login to Lucky Supermarkets is needed for the API response. You call ReefAPI with your x-api-key header, and the playground can run live examples before you create a production key.
How fresh is the Lucky Supermarkets data?
The page example is captured from a live search call, and production requests fetch live data through ReefAPI rather than a static sample.
How many credits does the Lucky Supermarkets API use?
Lucky Supermarkets actions currently cost 2-3 credits per successful call. Failed or blocked calls are free. All APIs draw from one credit pool.
Can I call Lucky Supermarkets from an AI assistant or MCP client?
Yes. Connect ReefAPI once through MCP and your assistant can call lucky-supermarkets actions with the same key, credit pool and JSON envelope used by normal REST requests.
