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

Create a specialized Hammer Product API with hammer type, weight, handle material, and tool specifications. Perfect for tool marketplaces and hardware retailers.

Introduction to Hammers

Hammers are fundamental tools found in every toolbox, from claw hammers to ball peen hammers, rubber mallets to sledgehammers. Finding the right hammer with the right specifications can be important for specific tasks. Whether you're a contractor needing a framing hammer, a DIY enthusiast looking for a claw hammer, or a developer building a tool marketplace, having structured hammer product data is crucial.

Imagine being able to search for hammers and instantly get detailed information about each tool - from hammer type and weight to handle material and grip type, from head material to special features. This is exactly what a specialized Hammer Product API can provide.

What Makes a Hammer API Special?

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

  • Hammer Type: Claw, ball peen, rubber mallet, sledge, framing, and more
  • Weight: Head weight for different applications
  • Handle: Material, length, and grip type
  • Head: Material and construction
  • Features: Magnetic head, anti-vibration, and specialized designs
  • Durability: Build quality and material selection
  • Ergonomics: Grip comfort and balance

With this structured data, you can build powerful features like filtering by hammer type, comparing weights, or recommending hammers based on intended use.

Try It Out: Search for Hammers

Use the search bar below to search for hammers. Try queries like "Estwing claw hammer 16oz", "DeWalt framing hammer", or "rubber mallet". 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 Hammer 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 Hammer 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., "hammer Estwing claw")
  • 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 Hammer-Specific JSON Schema to pass as custom_data_schema of search request

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

{
  "type": "object",
  "properties": {
    "hammer_type": {
      "type": "string",
      "enum": ["claw", "ball_peen", "rubber_mallet", "sledge", "framing", "tack", "dead_blow", "brass"],
      "description": "Type of hammer"
    },
    "weight": {
      "type": "string",
      "description": "Hammer head weight in ounces or pounds"
    },
    "handle_material": {
      "type": "string",
      "enum": ["wood", "fiberglass", "steel", "titanium", "rubber"],
      "description": "Handle material"
    },
    "handle_length": {
      "type": "string",
      "description": "Handle length in inches or centimeters"
    },
    "head_material": {
      "type": "string",
      "enum": ["steel", "titanium", "brass", "rubber", "plastic"],
      "description": "Head material"
    },
    "grip_type": {
      "type": "string",
      "enum": ["smooth", "textured", "rubber", "cushioned"],
      "description": "Grip type"
    },
    "magnetic": {
      "type": "boolean",
      "description": "Whether the hammer has a magnetic head"
    },
    "anti_vibration": {
      "type": "boolean",
      "description": "Whether the hammer has anti-vibration features"
    },
    "price_range": {
      "type": "string",
      "description": "Price range category"
    }
  },
  "required": ["hammer_type", "weight", "handle_material"]
}

Using the Category Prefix

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

Example Search Queries:

  • hammer Estwing claw 16oz
  • hammer DeWalt framing
  • hammer rubber mallet
  • hammer ball peen

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

Complete Example: Making a Request

Here's how to make a request to The Product API with a hammer-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=hammer%20Estwing%20claw&with_image=true', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_KEY'
  },
  body: JSON.stringify({
    custom_data_schema: {
      type: "object",
      properties: {
        hammer_type: {
          type: "string",
          enum: ["claw", "ball_peen", "rubber_mallet", "sledge", "framing", "tack", "dead_blow", "brass"],
          description: "Type of hammer"
        },
        weight: {
          type: "string",
          description: "Hammer head weight in ounces or pounds"
        },
        handle_material: {
          type: "string",
          enum: ["wood", "fiberglass", "steel", "titanium", "rubber"],
          description: "Handle material"
        },
        handle_length: {
          type: "string",
          description: "Handle length"
        },
        head_material: {
          type: "string",
          enum: ["steel", "titanium", "brass", "rubber", "plastic"],
          description: "Head material"
        },
        grip_type: {
          type: "string",
          enum: ["smooth", "textured", "rubber", "cushioned"],
          description: "Grip type"
        },
        magnetic: {
          type: "boolean",
          description: "Whether the hammer has a magnetic head"
        },
        anti_vibration: {
          type: "boolean",
          description: "Whether the hammer has anti-vibration features"
        },
        price_range: {
          type: "string",
          description: "Price range category"
        }
      },
      required: ["hammer_type", "weight", "handle_material"]
    }
  })
});

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": "Estwing E3-16C Claw Hammer",
      "description": "The Estwing E3-16C is a classic claw hammer...",
      "brand": "Estwing",
      "image": "https://example.com/image.jpg",
      "custom_data": {
        "hammer_type": "claw",
        "weight": "16 oz",
        "handle_material": "steel",
        "handle_length": "13 inches",
        "head_material": "steel",
        "grip_type": "rubber",
        "magnetic": false,
        "anti_vibration": true,
        "price_range": "mid-range"
      }
    }
  ]
}

Conclusion

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

  1. Define your schema based on what hammer 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!
