Frequently Asked Questions

Why am I getting rate limit errors?

Rate limits depend on your subscription plan. Check your current usage in the dashboard and consider upgrading if you need higher limits. View our pricing plans for details.

How do I secure my API key?

Never expose API keys in client-side code. Use environment variables and keep keys secure on your server. Regenerate keys if compromised. Learn more in our security documentation.

Why is my request returning 404?

This usually means the UPC code doesn't exist in our database yet. Try searching through our web interface first to verify the product exists.
