This guide provides best practices and recommendations for developers integrating with the Pure API.

​
Rate Limiting

While we don’t publish specific rate limits, we do monitor API usage to ensure fair access for all users. If you’re planning to make a large number of requests, please contact us at [email protected] to discuss your needs.

​
Error Handling

The API returns standard HTTP status codes to indicate success or failure:
  • 200 OK: The request was successful
  • 400 Bad Request: The request was invalid or improperly formatted
  • 401 Unauthorized: Authentication failed (invalid or missing API key)
  • 404 Not Found: The requested resource was not found
  • 500 Internal Server Error: An unexpected error occurred on the server
All error responses include an error field with a description of what went wrong: 
{
  "error": "Detailed error message"
}

​
Pagination

For endpoints that return multiple items (like /products), we use offset-based pagination: 
GET /products?offset=0&limit=10
  • offset: Number of items to skip (default: 0)
  • limit: Maximum number of items to return (default: 10, max: 100)

​
Handling Spot Prices

Spot prices for precious metals can change rapidly. When displaying spot prices to users, consider:
  1. Showing the timestamp (updatedAt) to indicate when the price was last updated
  2. Implementing a refresh mechanism to fetch updated prices periodically
  3. Displaying the market status (marketOpen) to indicate if the market is currently active

​
Working with Product Data

When working with product data, keep in mind:
  1. Products may have multiple variants with different pricing
  2. The highestOffer and lowestListing fields represent the current market state and may be null if no offers/listings exist
  3. Premium calculations can vary by product subcategory (check the premiumCalculationType field)

​
Testing

We recommend testing your integration thoroughly before deploying to production. Use the following approach:
  1. Start with the /protected endpoint to verify authentication
  2. Test with a small subset of products before implementing full integration
  3. Implement proper error handling for all API calls
  4. Consider implementing retry logic for transient errors
