# Product Lookup

### Overview

The PRODUCT\_LOOKUP operation serves as a universal translator for e-commerce identifiers. By leveraging Easyparser’s advanced Amazon scraping engine, this operation allows you to search for Amazon products using global identifiers such as `ASIN`, `EAN`, `GTIN`, `ISBN`, `JAN`, `MINSAN`, `UPC` or simply by providing a specific keyword. It extracts real-time product information directly from Amazon, ensuring your data is always current and accurate.

The primary goal of this operation is to bridge the gap between global retail standards and the Amazon ecosystem. The returned data includes comprehensive details such as the ASIN, official product title, brand, manufacturer, and high-resolution image URLs.

A standout feature of this operation is its Bi-Directional Mapping Capability. While traditional tools focus solely on a "Barcode to ASIN" workflow, Easyparser supports both directions:

* Identifier to ASIN: Convert EAN, UPC, or GTIN codes into their corresponding Amazon listings.
* ASIN to Identifiers: Provide an ASIN and retrieve the full set of associated global codes (UPC, EAN, GTIN, etc.) used in the broader retail market.

This flexibility ensures that whether you are starting with a physical barcode or an Amazon-specific identifier, you always receive the complete identity profile of the product.

### Key Capabilities

* **Universal Translation:** Seamlessly map between ASIN, EAN, GTIN, ISBN, JAN, MINSAN, and UPC.
* **One-to-Many Matching:** Accurately identify instances where a single global code (like a UPC) is associated with multiple Amazon listings.
* **Rich Metadata Extraction:** Beyond just codes, receive the manufacturer, model number, brand, and multiple image formats (Main, Thumbnail, and String URLs).
* **Identifier Transparency:** The `identifiers` array in the response provides every available code for the product, allowing you to cross-reference data across different marketplaces.

### Use Cases

* **Cross-Platform Listing & Sync**\
  Extract EANs or UPCs from Amazon ASINs to quickly list your products on external marketplaces like eBay, Walmart, or Google Shopping. This ensures that your entire multi-channel inventory is mapped to the same global standard.
* **Retail Arbitrage & Price Comparison**\
  Instantly find the corresponding Amazon listing and current price for products found in physical retail stores by using their UPC or EAN barcodes. This allows for real-time profitability analysis before making a purchase.
* **Inventory & ERP Bridging** \
  Establish a seamless link between your internal Enterprise Resource Planning (ERP) system or Warehouse Management System (WMS)—typically indexed by UPCs—and live Amazon listing data. This eliminates manual data entry errors during inventory updates.
* **Catalog Data Enrichment (PIM)**\
  Automatically populate your Product Information Management (PIM) system with missing identifiers or manufacturer details. By performing an "ASIN to All Identifiers" lookup, you can fill in gaps in your database, such as missing EANs or Model Numbers.
* **Global Sourcing & Verification**\
  Use international codes like JAN (Japan) or MINSAN (Italy) to source and verify products from global markets and find their equivalents on other Amazon domains. This is essential for international distributors managing global supply chains.
* **Marketplace Integrity & Duplicate Detection** \
  Identify "ghost" listings or duplicate ASINs created for the same product. By searching with a single EAN or UPC, you can see if multiple Amazon listings are competing for the same physical product, allowing you to focus on the most authoritative listing.
* **Legacy Catalog Migration**\
  Convert your existing legacy store's database into Amazon-ready listings in bulk. By using your existing GTIN or ISBN data, you can map thousands of products to their Amazon counterparts in a single batch operation through our Bulk API.

### Who Can Benefit?

* **Multi-Channel E-Commerce Sellers**\
  Strategic merchants who operate across multiple platforms (such as eBay, Walmart, and Shopify) can use this operation to ensure their catalog remains synchronized. By converting Amazon ASINs into universal identifiers like EANs or UPCs, they can maintain a single, unified inventory source across all sales channels.
* **Retail Arbitrage Professionals & Resellers**\
  For those who source products from physical stores or liquidations, the ability to instantly match a barcode (UPC/EAN) to an Amazon listing is a game-changer. It allows for rapid decision-making by revealing the product’s current sales rank, price, and competitive landscape in seconds.
* **Logistics & Supply Chain Managers**\
  Professionals managing large-scale warehouse operations benefit by closing the gap between physical inventory—typically labeled with EANs/UPCs—and digital Amazon listings. This operation ensures that shipping labels, FBA shipments, and stock counts are perfectly aligned with the correct ASINs.
* **Market Researchers & Competitive Analysts**\
  Data-driven analysts use this tool to map the competitive landscape. By identifying all ASINs tied to a single GTIN, they can uncover listing fragmentation, analyze brand saturation, and track how different sellers are positioning the same manufacturer product.
* **Brand Protection & Legal Compliance Teams**\
  Manufacturers and brand owners can monitor their global footprint. By searching for their official UPCs or GTINs, they can identify unauthorized "ghost" listings, duplicate entries, or international variants (via JAN or MINSAN) that might be diluting their brand presence or violating MAP pricing.
* **SaaS Developers & Inventory Tool Creators**\
  Developers building inventory management systems, ERP integrations, or repricing software can use this API as a "universal adapter." It allows their applications to accept any standard product code from end-users and instantly translate it into rich, actionable Amazon data.
* **Procurement and Sourcing Specialists** \
  For organizations that source products globally, this operation provides the necessary tools to identify local market equivalents. Using international identifiers like ISBN (for books) or MINSAN (for Italian medical/health products) ensures that sourcing remains accurate across different Amazon regions.

### Accepted Input Types

To ensure global compatibility, the operation accepts the following seven identifier types:<br>

1. ASIN: Amazon Standard Identification Number.
2. EAN: European Article Number.
3. GTIN: Global Trade Item Number.
4. ISBN: International Standard Book Number.
5. JAN: Japanese Article Number.
6. MINSAN: Italian Ministry of Health Code.
7. UPC: Universal Product Code.

### Available Through

The PRODUCT\_LOOKUP operation is fully accessible through two primary integration methods, allowing you to choose the best approach based on your data volume and speed requirements.

**Real-Time Integration** \
Used for instant identifier conversion and on-the-fly product matching. This method is ideal for real-time mobile applications, in-store barcode scanning, or immediate verification of a single product’s Amazon identity for quick decision-making.

**Bulk Integration**\
Used for asynchronously translating thousands of product identifiers at scale. This integration is perfect for large-scale catalog migration, synchronizing entire enterprise inventory databases (EAN/UPC to ASIN), and identifying product matches across massive datasets for comprehensive market analysis and data enrichment.
