Catalog API Reference

Complete API reference for product search, discovery, and commerce intelligence endpoints. Includes authentication, request/response formats, and error handling.

The Catalog API provides powerful endpoints for product search, discovery, and commerce intelligence. Build intelligent shopping experiences with natural language search, detailed product data, and real-time availability information.

What is the API base URL?

All API endpoints use the base URL:

https://api.getcatalog.ai

How do you authenticate API requests?

All requests require your API key in the x-api-key header. Get your API key if you don’t have one yet.

curl -H "x-api-key: YOUR_API_KEY" https://api.getcatalog.ai/api/search

Keep your API key secure and never expose it in client-side code. Store it in environment variables or secure configuration.

      }
    }
  ],
  "meta": {
    "totalItems": 42,
    "totalPages": 5,
    "currentPage": 1,
    "pageSize": 10
  }
}

How does the API handle errors?

The API returns errors with standard HTTP status codes and detailed error information to help you troubleshoot issues quickly:

{
  "error": {
    "code": "INVALID_PARAMETER",
    "message": "The 'query' parameter must be a string",
    "details": {

    }
