Building a Pressure Washer API with The Product API: A Complete Guide

Introduction to Pressure Washers

Pressure washers are powerful cleaning tools essential for maintaining outdoor spaces, vehicles, and surfaces. From gas-powered models for heavy-duty commercial use to electric models for residential cleaning, finding the right pressure washer with the right specifications is crucial for any cleaning task. Whether you're a professional contractor needing a high-PSI gas pressure washer, a homeowner looking for an electric model, or a developer building a tool marketplace, having structured pressure washer product data is essential.

Imagine being able to search for pressure washers and instantly get detailed information about each tool - from power source to pressure rating. This is exactly what a specialized Pressure Washer Product API can provide.

What Makes a Pressure Washer API Special?

A Pressure Washer Product API goes beyond basic product listings. It understands the unique characteristics that matter to pressure washer buyers:

• Power Source: Gas, electric, or battery-powered operation
• Pressure: The PSI (pounds per square inch) rating for different cleaning applications

With this structured data, you can build powerful features like filtering by power source, comparing pressure ratings, or recommending pressure washers based on cleaning needs.

Try It Out: Search for Pressure Washers

Use the search bar below to search for pressure washers. Try queries like "Karcher electric pressure washer", "Ryobi battery pressure washer", or "Honda gas 3000 PSI pressure washer". 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 Pressure Washer 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 Pressure Washer 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., "pressure washer Karcher electric")
• 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 Pressure Washer-Specific JSON Schema to pass as custom_data_schema of search request

Here's the JSON Schema we use for pressure washer products:

{
  "type": "object",
  "properties": {
    "power_source": {
      "type": "string",
      "enum": ["gas", "electric", "battery"],
      "description": "Power source type"
    },
    "pressure": {
      "type": "string",
      "description": "Pressure rating in PSI (e.g., '2000 PSI', '3000 PSI', '4000 PSI')"
    }
  },
  "required": ["power_source"]
}

Using the Category Prefix

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

Example Search Queries:

• pressure washer Karcher electric
• pressure washer Ryobi battery
• pressure washer Honda gas 3000 PSI
• pressure washer electric corded

The prefix "pressure washer" ensures the API understands you're looking specifically for pressure washers and not other products.

Complete Example: Making a Request

Here's how to make a request to The Product API with a pressure washer-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=pressure%20washer%20Karcher%20electric&with_image=true', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
  },
  body: JSON.stringify({
    custom_data_schema: {
      type: "object",
      properties: {
        power_source: {
          type: "string",
          enum: ["gas", "electric", "battery"],
          description: "Power source type"
        },
        pressure: {
          type: "string",
          description: "Pressure rating in PSI"
        }
      },
      required: ["power_source"]
    }
  })
});

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": "Karcher K5 Premium Electric Pressure Washer",
      "description": "The Karcher K5 Premium is a powerful electric pressure washer...",
      "brand": "Karcher",
      "image": "https://example.com/image.jpg",
      "custom_data": {
        "power_source": "electric",
        "pressure": "2000 PSI"
      }
    }
  ]
}

Conclusion

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

1. Define your schema based on what pressure washer 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!
