Using ApplianceAPI with ChatGPT and AI Workflows

Custom GPT Setup

Register ApplianceAPI as a custom GPT action in three steps:

1. Create a new GPT in ChatGPT and open the "Actions" configuration
2. Add the action schema with the ApplianceAPI endpoint URL (https://applianceapi.com/api/v1/images) and set authentication to API key in the Authorization header
3. Test with a model number — ask your GPT to look up "Whirlpool WRS325SDHZ" and verify the JSON response

Function Calling Example

Define an OpenAI function that wraps the ApplianceAPI model lookup endpoint:

{
  "name": "lookup_appliance",
  "description": "Look up an appliance by brand and model number",
  "parameters": {
    "type": "object",
    "properties": {
      "brand": { "type": "string", "description": "Appliance brand name" },
      "model": { "type": "string", "description": "Model number" }
    },
    "required": ["brand", "model"]
  }
}

When the function is called, make a GET request to /api/v1/images?brand={brand}&model={model} with your API key and return the JSON response.

Custom GPT Action Schema

Register ApplianceAPI as a GPT action to give your custom GPT appliance lookup capabilities:

{
  "openapi": "3.0.0",
  "info": { "title": "ApplianceAPI", "version": "1.0" },
  "servers": [{ "url": "https://www.applianceapi.com" }],
  "paths": {
    "/api/v1/images": {
      "get": {
        "summary": "Look up appliance by model number",
        "parameters": [
          { "name": "brand", "in": "query", "required": true, "schema": { "type": "string" } },
          { "name": "model", "in": "query", "required": true, "schema": { "type": "string" } }
        ]
      }
    }
  }
}

Add your API key as the authentication header. The GPT can then answer questions like "look up Samsung WF45T6000AW" by calling the API directly.

Function Calling Example

For OpenAI function calling (tools API), define ApplianceAPI as a tool:

{
  "type": "function",
  "function": {
    "name": "lookup_appliance",
    "description": "Look up appliance data by brand and model number",
    "parameters": {
      "type": "object",
      "properties": {
        "brand": { "type": "string", "description": "Appliance brand name" },
        "model": { "type": "string", "description": "Model number" }
      },
      "required": ["brand", "model"]
    }
  }
}

When the model calls this function, your backend makes the HTTP request to ApplianceAPI and returns the JSON response as the function result.

Real-World GPT Use Cases

Custom GPTs powered by ApplianceAPI can serve specific industry workflows:

• Inspection Report Assistant — "Decode this serial number and write an inspection note for a Whirlpool WRS325SDHZ manufactured in 2016."
• Warranty Eligibility Checker — "Is this appliance (model WTW5000DW, serial CS4291847) still under a 10-year warranty?"
• Repair Cost Estimator — "Look up this Samsung refrigerator model, estimate its age, and suggest whether to repair or replace based on typical repair costs."
• Property Inventory Builder — "For each of these 8 model numbers, get the brand, product title, age, and photo URL. Format as a property inventory spreadsheet."
