Allegro EAN Price Tracker — All Sellers + Hidden Discount Detection (Poland)

Give it an EAN / GTIN code, get back every seller offering that product on Allegro.pl plus their prices — sorted, filtered, with min / max / average computed for you. Plus the only tool on the market that reveals Allegro's hidden price modifications (Lowest Price Guarantee). A premium tool for brands, distributors, dropshippers, and repricers who work with EAN lists, not URLs.

What it does

For each EAN, the actor:

1. Finds the product — searches Allegro for the EAN via Bright Data Web Unlocker (which passes DataDome on the search page) and resolves the matching product.
2. Caches the match — the EAN → product mapping is cached for 24h, so repeat runs skip the search step.
3. Pulls every offer — opens the product's "Wszystkie oferty" list and extracts all sellers, prices, ratings, delivery and Allegro Smart! status.
4. Filters, sorts, caps — Smart!-only / exclude-Smart, drop sponsored, sort by price or seller rating, keep the top N — then computes lowest / highest / average price.
5. Detects hidden discounts — for every returned offer it checks whether Allegro is silently lowering the price below what the seller actually set (see below).

EAN not on Allegro? You get a clean found: false row — and you are not charged for it.

🏆 Hidden Discount Detection (Unique Feature)

Did you know Allegro silently modifies prices? When an offer carries the "Gwarancja najniższej ceny" (Lowest Price Guarantee) badge, Allegro may show buyers a lower price than the seller actually set — and the public offer data hides this completely (price.original: null).

Example from live data: a seller sets 139.19 PLN. Buyers see 133.90 PLN. Allegro absorbs the 5.29 PLN (3.8%) difference — and no other scraper on the market can tell you this happened.

This actor reveals it. For every offer you get:

Field	Meaning
publicPrice	What buyers see on Allegro
realSellerPrice	What the seller actually set
allegroDiscount	The hidden difference in PLN (0 if none)
allegroDiscountPercent	The hidden difference in %
hasLowestPriceGuarantee	Offer participates in the Lowest Price Guarantee program (badge)
hasHiddenDiscount	Allegro is actively lowering this offer's price right now

Both states are valuable: hasLowestPriceGuarantee: true with hasHiddenDiscount: false is a verified confirmation that the seller's own price is already the lowest (Allegro isn't touching it). When hasHiddenDiscount: true, you see exactly how deep Allegro is cutting.

Here's a live run in the Apify dataset view — per EAN you instantly see how many offers carry the guarantee, how many Allegro is actively discounting, and the total hidden discount:

Why this matters:

• MAP monitoring — your distributor's set price may be compliant while the displayed price violates MAP. Only this actor sees both.
• Repricing — competing against publicPrice when the competitor's real price is higher means you're racing Allegro's wallet, not the seller's. Know the difference.
• Market intelligence — see which products and sellers Allegro subsidizes and by how much.

Opt-in: enable with detectHiddenDiscounts: true (default false). Offers verified for the guarantee are billed at a premium rate (see Pricing) — leave it off for plain price tracking at the standard rate.

• ⭐ Seller rating, review count & Super Seller badge

⚠️ Prices are consumer (B2C), gross

This actor returns consumer allegro.pl offers with gross (brutto, incl. VAT) prices. Allegro's business marketplace (business.allegro.pl) is a separate listing with net (netto) prices and often a different set of sellers — results here will not match the B2B view 1:1. (Native B2B support is on the roadmap — contact support@klevio.pl.)

Use cases

• MAP monitoring — brands tracking minimum-advertised-price violations
• Distributor pricing — daily tracking of partner / reseller pricing
• Dropshipping — find the cheapest supplier for your EAN list
• Repricing — competitive intelligence at scale
• Market intelligence — price distribution across sellers

Pricing

Pay-per-event — you pay only for what's actually resolved:

Event	Price	When
Product resolved	$0.03 ($30 / 1000)	Per EAN successfully matched (fresh or cached)
Offer scraped	$0.003 ($3 / 1000)	Per standard offer in the result
Offer with GNC detection	$0.10	Per offer verified for the Lowest Price Guarantee (badge present — real seller price resolved & compared)
Run start fee	$0.05	Once per run

Unmatched EANs are FREE — no charge. Each offer is billed either as standard or as GNC-verified — never both. The GNC rate applies only when you opt in with detectHiddenDiscounts: true (default false — plain price tracking at the standard rate).

Example (standard): 100 EAN × 8 sellers avg ≈ 100 × $0.03 + 800 × $0.003 + $0.05 = ~$5.45 per run. Example (with Hidden Discount Detection): same run, ~5% of offers in the guarantee program ≈ 100 × $0.03 + 760 × $0.003 + 40 × $0.10 + $0.05 = ~$9.33 per run. The 40 premium offers tell you the real seller price + Allegro's exact hidden cut — data no other tool has.

Already have product URLs?

If you have Allegro product/offer URLs (not EANs), use our lighter sibling — it skips the EAN-search step: Allegro Price Comparison — All Sellers by URL.

FAQ

How do I track prices for my product list by EAN? Paste your EAN/GTIN codes (up to 1000). For each, the actor finds the Allegro product and returns every seller's offer with price, rating, Smart! and delivery — sorted cheapest-first by default.

What does the smart flag mean? The real Allegro Smart! status, read from the offer's Smart! badge — not simply "free delivery" (a Smart! offer can have paid delivery for non-subscribers). Filter with smartFilter.

What is Hidden Discount Detection? When an offer has Allegro's "Gwarancja najniższej ceny" (Lowest Price Guarantee) badge, Allegro may silently show buyers a lower price than the seller set — invisible in public data. This actor resolves the real seller price for every such offer and reports the exact hidden discount (allegroDiscount). Even when the discount is zero, you get verified confirmation the seller's own price is the lowest. Opt in with detectHiddenDiscounts: true (off by default).

Why might a price differ from what I see on Allegro? Two reasons. (1) The offer may have a hidden Allegro discount — check realSellerPrice vs publicPrice. (2) You may be looking at business.allegro.pl (B2B, net prices, different sellers). This actor returns consumer offers with gross prices — see the note above.

What if an EAN isn't on Allegro? You get a found: false row and are not charged for it.

What if an EAN matches more than one product? Allegro sometimes lists the same item under several product pages — e.g. a single unit and a "Zestaw 2 sztuk" (2-pack), which are different products with their own offers. When the search returns more than one distinct product, the actor uses the first (most relevant) match and sets multipleMatches: true so you can flag those rows for review. Sponsored and organic cards for the same product page are de-duplicated automatically (counted as one). If you need a specific representation, pass its product URL to our sibling Allegro Price Comparison by URL.

How does the cache work? The EAN → product mapping is cached for 24h. A cache hit skips the search step — repeat runs are faster (you pay the same).

How do I find the cheapest seller? Keep sortBy: "price-asc" (default) — offers[0] and lowestPrice give the cheapest current offer with the seller's login, rating and Super Seller status.

How do I run this programmatically? Call the actor from the Apify API or SDK with a JSON input (eans, topNOffers, sortBy, …). Poll the run and read the dataset as JSON/CSV. Schedule it for recurring tracking.

Can I exclude sponsored offers? Yes — set includePromoted: false.

How do you bypass Allegro's anti-bot (DataDome)? EAN search goes through Bright Data Web Unlocker (solves the challenge on the search endpoint), and the offers page through a managed Scraping Browser with a fresh IP per product.

Is this legal / GDPR-compliant? The actor reads only public offer data — no buyer data, no reviews/PII. Seller logins/IDs are public business identifiers. Allegro's ToS restrict automated access; use responsibly and consult a lawyer for commercial use.

Can I push results to BaseLinker? The output is BaseLinker-friendly (EAN, price, seller, offer URL). Native sync is on our roadmap — for a custom workflow now, email support@klevio.pl.

🇵🇱 Najczęściej zadawane pytania (Polski)

Jak działa monitoring cen Allegro po EAN/GTIN?

Wpisujesz listę kodów EAN — aktor automatycznie znajduje każdy produkt na Allegro.pl i pobiera ceny wszystkich sprzedawców tego produktu. Idealne dla MAP monitoring marki.

Czy mogę śledzić ceny moich produktów codziennie?

Tak. Apify ma wbudowany scheduler — ustaw cron „codziennie o 6:00" i aktor sam się uruchomi. Możesz też dostawać alerty webhook do Slacka/maila gdy cena spadnie poniżej progu. Cache 24h sprawia, że powtórne uruchomienia są szybsze.

Ile to kosztuje dla 200 produktów codziennie?

200 EAN × 8 sprzedawców × 30 dni ≈ 330 USD/miesiąc (~1320 PLN) w trybie standardowym. Jeśli świadomie włączysz wykrywanie ukrytych rabatów (detectHiddenDiscounts: true — domyślnie wyłączone), oferty z Gwarancją najniższej ceny rozliczane są po stawce premium $0.10 — przy typowych ~5% takich ofert to ok. 560 USD/miesiąc za pełny obraz rynku, łącznie z cenami, których nie widzi żadne inne narzędzie.

Czym jest wykrywanie ukrytych rabatów (Gwarancja najniższej ceny)?

Gdy oferta ma odznakę „Gwarancja najniższej ceny", Allegro może po cichu pokazywać kupującym niższą cenę niż ustawił sprzedawca — publiczne dane tego nie zdradzają. Ten aktor (jako jedyny na rynku) ustala prawdziwą cenę sprzedawcy i podaje dokładną kwotę ukrytego rabatu (allegroDiscount, np. sprzedawca ustawił 139.19 zł, kupujący widzi 133.90 zł → rabat Allegro 5.29 zł). Gdy rabatu nie ma, dostajesz zweryfikowane potwierdzenie, że cena sprzedawcy jest już najniższa. Funkcja jest domyślnie wyłączona — włączasz świadomie przez detectHiddenDiscounts: true (oferty z Gwarancją rozliczane wtedy po stawce premium).

Co oznacza flaga smart?

To prawdziwy status Allegro Smart! (odczytany z odznaki „Smart!"), a NIE darmowa dostawa — oferta Smart! bywa z płatną dostawą dla osób bez subskrypcji. Filtruj przez smartFilter.

Czy wyniki dotyczą business.allegro.pl (B2B)?

Nie — aktor zwraca oferty konsumenckie z allegro.pl w cenach brutto. business.allegro.pl to osobny rynek B2B z cenami netto i często innym zestawem sprzedawców, więc wyniki nie będą się pokrywać 1:1 z widokiem B2B. Natywne B2B jest na roadmapie → support@klevio.pl

Co jeśli jeden EAN pasuje do kilku produktów?

Allegro czasem listuje ten sam towar pod kilkoma stronami produktu (np. sztuka pojedyncza i „Zestaw 2 sztuk"). Gdy search zwróci więcej niż jeden różny produkt, aktor bierze pierwszy (najtrafniejszy) i ustawia multipleMatches: true. Karty sponsorowane i organiczne tego samego produktu są deduplikowane (liczone jako jeden).

Czy mogę zintegrować z BaseLinker?

Output JSON jest kompatybilny z BL Inventory (EAN, cena, sprzedawca) — łatwy import. Potrzebujesz custom integracji? → support@klevio.pl

Czy ceny są w PLN czy USD?

Cena za aktora: USD (standard Apify). Ceny produktów Allegro: PLN (waluta lokalna).

Co jeśli EAN nie istnieje na Allegro?

Aktor zwraca {found: false} BEZ obciążenia kosztem. Płacisz tylko za udane resolucje.
