Pass store_id to read that store's price and stock. The same EAN in another store is a different response. On 30 Oct 2026, the LEGO Duplo fire station 5702016367676 is in stock at Marennes (1017, 39.90 EUR, stock 1) and has no local offer at Coutras (1833, no price, stock 0). A store that does not sell the product still returns the product, with offer.elected_offer.shop_id set to the requested store.
- If
store_id is not provided, the product is fetched from the national E.Leclerc online store.
environmental_cost is null when E.Leclerc does not publish a score for that product.- Marketplace products resolve from catalog IDs when the national
o-{ean} offer is missing.
cnc_offers_count indicates how many physical stores have Click & Collect availability.
