Building a Wine API with The Product API: A Complete Guide

Introduction to Wine

Wine is one of the world's most celebrated beverages, enjoyed by millions for its complexity, variety, and cultural significance. From bold reds to crisp whites, finding the right wine with the right characteristics is essential for wine enthusiasts, restaurants, and retailers. Whether you're building a wine marketplace, creating a subscription service, or developing a wine shop management system, having structured wine product data is essential.

Imagine being able to search for wine and instantly get detailed information about each product - from wine type and region to vintage year. This is exactly what a specialized Wine Product API can provide.

What Makes a Wine API Special?

A Wine Product API goes beyond basic product listings. It understands the unique characteristics that matter to wine buyers:

• Wine Type: Red, white, rosé, or sparkling - each offering distinct flavor profiles
• Region: The geographic region where the wine was produced (e.g., Bordeaux, Napa Valley, Tuscany)
• Vintage: The year the grapes were harvested, which can significantly impact flavor and value

With this structured data, you can build powerful features like filtering by wine type, discovering wines by region, or comparing products by vintage.

Try It Out: Search for Wine

Use the search bar below to search for wine. Try queries like "wine red Bordeaux", "wine white Napa Valley", "wine rosé 2020", or "wine sparkling". The results will include detailed specifications automatically extracted from product information across the web.

How It Works: Technical Implementation

Now that you've seen the API in action, let's dive into how it's implemented. This specialized Wine API is built on top of The Product API which is an AI-based product search API that works with any product and any type of query. It responds with structured JSON and supports custom structured responses, allowing you to build specialized APIs for any product category.

The Product API's powerful custom_data_schema feature allows you to define additional structured fields specific to your product category, enabling you to create category-specific APIs like this Wine API. For more details on how the API works, see the full documentation.

Understanding APIs for Product Data

An API (Application Programming Interface) enables different software applications to communicate. For product data:

• Input: You send a search query (e.g., "wine red Bordeaux")
• Processing: The API searches across multiple sources and uses AI to extract relevant information
• Output: You receive structured product data in JSON format

The flexibility of a product API means you can customize it for specific categories by defining additional data fields through JSON Schema.

Creating a Wine-Specific JSON Schema to pass as custom_data_schema of search request

Here's the JSON Schema we use for wine products:

{
  "type": "object",
  "properties": {
    "wine_type": {
      "type": "string",
      "enum": ["red", "white", "rosé", "sparkling"],
      "description": "Type of wine"
    },
    "region": {
      "type": "string",
      "description": "Wine region or origin (e.g., 'Bordeaux', 'Napa Valley', 'Tuscany')"
    },
    "vintage": {
      "type": "string",
      "description": "Vintage year (e.g., '2020', '2019')"
    }
  },
  "required": ["wine_type"]
}

Using the Category Prefix

When searching for wine, we prefix the search query with "wine" to help the AI understand the context and return more relevant results.

Example Search Queries:

• wine red Bordeaux
• wine white Napa Valley
• wine rosé 2020
• wine sparkling

The prefix "wine" ensures the API understands you're looking specifically for wine products and not other items.

Complete Example: Making a Request

Here's how to make a request to The Product API with a wine-specific schema. For complete API reference including authentication, endpoints, and all parameters, see the documentation:

const response = await fetch('https://api.example.com/api?search=wine%20red%20Bordeaux&with_image=true', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
  },
  body: JSON.stringify({
    custom_data_schema: {
      type: "object",
      properties: {
        wine_type: {
          type: "string",
          enum: ["red", "white", "rosé", "sparkling"],
          description: "Type of wine"
        },
        region: {
          type: "string",
          description: "Wine region or origin"
        },
        vintage: {
          type: "string",
          description: "Vintage year"
        }
      },
      required: ["wine_type"]
    }
  })
});

const data = await response.json();
console.log(data.products);

Expected Response

The API will return products with standard fields plus your custom custom_data field:

{
  "status": "success",
  "products": [
    {
      "name": "Red Wine Bordeaux 2020",
      "description": "Rich and full-bodied red wine from Bordeaux...",
      "brand": "WineBrand",
      "image": "https://example.com/image.jpg",
      "custom_data": {
        "wine_type": "red",
        "region": "Bordeaux",
        "vintage": "2020"
      }
    }
  ]
}

Conclusion

By combining the flexible Product API with a wine-specific JSON Schema, you can create a powerful, specialized API for wine products. The key is:

1. Define your schema based on what wine data matters to your application
2. Use category prefixes in search queries for better context
3. Leverage the custom_data field to build rich, category-specific features

The same approach works for any product category - you just need to define the right schema for your needs!
