Allegro product data API

ShopAPIS returns structured Allegro product data — price in PLN, offer status, seller name and rating, delivery cost, the platform’s structured parameter dictionary, EAN/GTIN and stock — as normalized JSON. Allegro is the dominant Western-CEE marketplace, and because most listings are sold by third-party merchants, a single popular product can carry dozens of competing offers at different prices. ShopAPIS resolves the cheapest live offer and the full seller spread for any product across Poland, Czechia and Slovakia.

Why Allegro data is hard to get

Allegro publishes a real REST API, but it serves merchants their own data — not a competitor’s price book. The official Allegro REST API  exposes offers, categories, the structured parameter dictionary, seller ratings and delivery for the account that authenticated, gated by OAuth. Reading the live marketplace — every seller’s price on a product, who currently holds the cheapest offer, how stock moves — means parsing the public storefront, which sits behind a Cloudflare/DataDome-class anti-bot layer with medium difficulty. The genuinely hard part is Allegro’s offer model: one product page is a marketplace of independent sellers, each with its own PLN price, condition, delivery cost and rating, and the winning offer rotates. ShopAPIS reconciles those competing offers into a clean array plus a resolved best-price field, so you see the real competitive picture rather than a single scraped number.
