Coreplex

Search products from brands that sell on Shopify. Each result says who sells it and whether that seller is the brand's official store, with a Coreplex link for full details. Prices and stock come from the live Shopify catalog at the time of the call. Checkout happens on the seller's own Shopify store; Coreplex adds no fees.

Details for one listing from the seller in the URL: price, stock, options, seller, official-store status and the seller's return and shipping policies. Prices and stock come from the live Shopify catalog at the time of the call. Checkout happens on the seller's own Shopify store; Coreplex adds no fees.

Price check for one item: other Shopify sellers of the exact same item (same Shopify catalog product or barcode), lowest first, plus similar listings from the same brand that may differ (shown separately and never counted as the same item). "Lowest" only covers sellers Coreplex found. Prices and stock come from the live Shopify catalog at the time of the call. Checkout happens on the seller's own Shopify store; Coreplex adds no fees.

{
  "type": "object",
  "properties": {
    "product_url": {
      "type": "string",
      "description": "The seller_url of the item to price-check."
    }
  },
  "required": [
    "product_url"
  ],

Brands Coreplex features because shoppers buy them most and each sells from its own official Shopify store (confirmed in the live catalog). Optionally filter by category.

{
  "type": "object",
  "properties": {
    "category": {
      "type": "string",
      "enum": [
        "baby",
        "home",
        "drinkware",
        "travel",
        "health",
        "beauty",
        "drinks",
        "tech",
        "pets",
        "fitness",
        "toys"
      ]
    }
  },
  "additionalProperties": false
}

Supplements and health items whose seller states a claim: HSA/FSA eligibility or a certification mark (USP, NSF, Informed Sport, GMP, ConsumerLab). Claims are seller-stated and not verified by Coreplex; shoppers should confirm with their plan or the certifier. Prices and stock come from the live Shopify catalog at the time of the call. Checkout happens on the seller's own Shopify store; Coreplex adds no fees.

      ]
    },

The product's passport: the brand's own listing as the baseline (price per size or style, options, availability), then every other Shopify store selling the same product, each marked same item, likely same item, or not the same (customized, bundle, refill or mini, accessory, used) with the evidence for the match and how its price compares with the brand's. Works from the brand's listing or any reseller's. Use it to tell a shopper whether to buy direct, who is cheaper, and which listings to avoid. Prices and stock come from the live Shopify catalog at the time of the call. Checkout happens on the seller's own Shopify store; Coreplex adds no fees.

    }
