How the sainsburys API works
sainsburys is a normal ReefAPI surface — the same four rules that hold for every other engine on the key.
No OAuth app, no request signing, no per-site account. One key covers all 384 engines.
Every route is a POST with a JSON body. Parameters are validated against the published schema before anything is charged.
Credits, not seats. Failed and blocked calls are never charged, and cache hits cost nothing.
One envelope everywhere. meta carries latency_ms, record_count and the endpoint that answered.
Search, then resolve the source identity
Use a result from the first call in the second call.
Read the source identity and price.
Replace the example identity with a fresh search result.
Source product detail within the documented scope.

}Coverage and limits
Measured on 2026-10-02. Core release-ready; not deployed.
United Kingdom; GBP prices; country=uk only.
Positive pages; variable page size. Stop when has_more is false. Requests above the source ceiling return the final page with page_clamped=true.
Pass id or url from search. Numeric product_uid alone is not a supported resolver.
EANs, eligible Nectar prices, promotions and nutrition sections are retained when published.
Explicit not-found pages return NOT_FOUND. A generic retailer error remains a retryable error because it does not prove the product is missing.

Get a free key →What is the sainsburys API?▾
sainsburys API is a ReefAPI endpoint group for sainsburys It returns live JSON through POST requests under /sainsburys/v1.
Is the sainsburys API free to try?▾
Yes. ReefAPI starts with 1,000 free credits, no card required. sainsburys calls use the same shared credit balance as every other ReefAPI engine.
Do I need a sainsburys login or account?▾
No login to sainsburys 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 sainsburys 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 sainsburys API use?▾
sainsburys actions currently cost 3 credits per successful call. Failed or blocked calls are free. All APIs draw from one credit pool.
Can I call sainsburys from an AI assistant or MCP client?▾
Yes. Connect ReefAPI once through MCP and your assistant can call sainsburys actions with the same key, credit pool and JSON envelope used by normal REST requests.
Is the sainsburys API a sainsburys scraper?▾
It is the managed alternative to a DIY sainsburys scraper. Instead of building and maintaining your own scraper — proxies, headless browsers, captcha and constant breakage — you call one ReefAPI endpoint and get the same sainsburys back as clean JSON.
Why does my sainsburys scraper keep getting blocked?▾
Most sainsburys scrapers break on anti-bot defenses, rate limits and IP bans that need rotating residential proxies and browser fingerprinting to clear. ReefAPI handles all of that for you — no proxies, no captchas, no maintenance — and returns live JSON. Blocked calls are free.
159 E-commerce & Marketplaces APIs on the same key
