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

Introduction to Sofas

Sofas are central pieces of furniture in any living space, providing comfort, style, and functionality. Whether you're a retailer building a furniture marketplace, a developer creating a home decor app, or a consumer furnishing a living room, having structured sofa product data is essential.

Imagine being able to search for sofas and instantly get detailed information about each piece - from material to color. This is exactly what a specialized Sofa Product API can provide.

What Makes a Sofa API Special?

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

• Material: The upholstery material - fabric, leather, microfiber, velvet, polyester, or cotton
• Color: The color of the sofa for matching and design coordination

With this structured data, you can build powerful features like filtering by material type, comparing colors, or recommending sofas based on style preferences.

Try It Out: Search for Sofas

Use the search bar below to search for sofa items. Try queries like "sofa leather brown", "sofa fabric gray", or "sofa velvet blue". 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 Sofa 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 Sofa 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., "sofa leather brown")
• 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 Sofa-Specific JSON Schema to pass as custom_data_schema of search request

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

{
  "type": "object",
  "properties": {
    "material": {
      "type": "string",
      "enum": ["fabric", "leather", "microfiber", "velvet", "polyester", "cotton"],
      "description": "Upholstery material"
    },
    "color": {
      "type": "string",
      "description": "Sofa color (e.g., 'brown', 'black', 'white', 'gray', 'beige', 'blue', 'red')"
    }
  },
  "required": ["material", "color"]
}

Using the Category Prefix

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

Example Search Queries:

• sofa leather brown
• sofa fabric gray
• sofa velvet blue
• sofa microfiber beige

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

Complete Example: Making a Request

Here's how to make a request to The Product API with a sofa-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=sofa%20leather%20brown&with_image=true', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
  },
  body: JSON.stringify({
    custom_data_schema: {
      type: "object",
      properties: {
        material: {
          type: "string",
          enum: ["fabric", "leather", "microfiber", "velvet", "polyester", "cotton"],
          description: "Upholstery material"
        },
        color: {
          type: "string",
          description: "Sofa color"
        }
      },
      required: ["material", "color"]
    }
  })
});

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": "Brown Leather Sofa",
      "description": "A comfortable brown leather sofa with modern design...",
      "brand": "Furniture Co",
      "image": "https://example.com/image.jpg",
      "custom_data": {
        "material": "leather",
        "color": "brown"
      }
    }
  ]
}

Conclusion

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

1. Define your schema based on what sofa 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!
