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

Introduction to Chairs

Chairs are fundamental pieces of furniture found in every home, office, and commercial space. From ergonomic office chairs for productivity to comfortable dining chairs for family meals, finding the right chair with the right specifications is crucial for comfort and functionality. Whether you're furnishing an office, setting up a dining room, or building a furniture marketplace, having structured chair product data is essential.

Imagine being able to search for chairs and instantly get detailed information about each chair - from material to type. This is exactly what a specialized Chair Product API can provide.

What Makes a Chair API Special?

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

• Material: The primary construction material - wood, metal, plastic, fabric, or leather
• Type: The style and intended use - office, dining, gaming, armchair, barstool, or recliner

With this structured data, you can build powerful features like filtering by material, comparing chair types, or recommending chairs based on intended use.

Try It Out: Search for Chairs

Use the search bar below to search for chairs. Try queries like "Herman Miller office chair", "wooden dining chair", or "gaming chair leather". 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 Chair 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 Chair 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., "chair Herman Miller office")
• 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 Chair-Specific JSON Schema to pass as custom_data_schema of search request

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

{
  "type": "object",
  "properties": {
    "material": {
      "type": "string",
      "enum": ["wood", "metal", "plastic", "fabric", "leather"],
      "description": "Primary material of the chair"
    },
    "type": {
      "type": "string",
      "enum": ["office", "dining", "gaming", "armchair", "barstool", "recliner"],
      "description": "Chair type or style"
    }
  },
  "required": ["type"]
}

Using the Category Prefix

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

Example Search Queries:

• chair Herman Miller office
• chair wooden dining
• chair gaming leather
• chair fabric armchair

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

Complete Example: Making a Request

Here's how to make a request to The Product API with a chair-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=chair%20Herman%20Miller%20office&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: ["wood", "metal", "plastic", "fabric", "leather"],
          description: "Primary material of the chair"
        },
        type: {
          type: "string",
          enum: ["office", "dining", "gaming", "armchair", "barstool", "recliner"],
          description: "Chair type or style"
        }
      },
      required: ["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": "Herman Miller Aeron Office Chair",
      "description": "The Herman Miller Aeron is an ergonomic office chair designed for comfort and productivity...",
      "brand": "Herman Miller",
      "image": "https://example.com/image.jpg",
      "custom_data": {
        "material": "fabric",
        "type": "office"
      }
    }
  ]
}

Conclusion

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

1. Define your schema based on what chair 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!
