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

Introduction to Skincare

Skincare products are essential for maintaining healthy, radiant skin. From cleansers and moisturizers to serums and sunscreens, finding the right skincare product with the right specifications is crucial for any skincare routine. Whether you're a retailer building a skincare catalog, a developer creating a beauty app, or a consumer looking for products suited to your skin type, having structured skincare product data is essential.

Imagine being able to search for skincare products and instantly get detailed information about each item - from product type to skin type compatibility. This is exactly what a specialized Skincare Product API can provide.

What Makes a Skincare API Special?

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

• Product Type: The category - cleanser, moisturizer, serum, sunscreen, toner, exfoliant, mask, or eye cream
• Skin Type: The recommended skin type compatibility - all skin types, dry, oily, combination, sensitive, or normal

With this structured data, you can build powerful features like filtering by product type, matching products to skin types, or recommending items based on user preferences and needs.

Try It Out: Search for Skincare

Use the search bar below to search for skincare products. Try queries like "skincare CeraVe cleanser", "skincare La Roche-Posay moisturizer", or "skincare The Ordinary serum". 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 Skincare 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 Skincare 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., "skincare CeraVe cleanser")
• 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 Skincare-Specific JSON Schema to pass as custom_data_schema of search request

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

{
  "type": "object",
  "properties": {
    "product_type": {
      "type": "string",
      "enum": ["cleanser", "moisturizer", "serum", "sunscreen", "toner", "exfoliant", "mask", "eye cream"],
      "description": "Type of skincare product"
    },
    "skin_type": {
      "type": "string",
      "enum": ["all skin types", "dry", "oily", "combination", "sensitive", "normal"],
      "description": "Recommended skin type"
    }
  },
  "required": ["product_type"]
}

Using the Category Prefix

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

Example Search Queries:

• skincare CeraVe cleanser
• skincare La Roche-Posay moisturizer
• skincare The Ordinary serum
• skincare Neutrogena sunscreen

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

Complete Example: Making a Request

Here's how to make a request to The Product API with a skincare-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=skincare%20CeraVe%20cleanser&with_image=true', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
  },
  body: JSON.stringify({
    custom_data_schema: {
      type: "object",
      properties: {
        product_type: {
          type: "string",
          enum: ["cleanser", "moisturizer", "serum", "sunscreen", "toner", "exfoliant", "mask", "eye cream"],
          description: "Type of skincare product"
        },
        skin_type: {
          type: "string",
          enum: ["all skin types", "dry", "oily", "combination", "sensitive", "normal"],
          description: "Recommended skin type"
        }
      },
      required: ["product_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": "CeraVe Hydrating Cleanser",
      "description": "Gentle hydrating cleanser for normal to dry skin...",
      "brand": "CeraVe",
      "image": "https://example.com/image.jpg",
      "custom_data": {
        "product_type": "cleanser",
        "skin_type": "dry"
      }
    }
  ]
}

Conclusion

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

1. Define your schema based on what skincare 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!
