These terms govern your use of OnlineShippingCalculator.com, including our website, rate calculators, and public APIs such as our Model Context Protocol (MCP) server (together, the “Service”). By using the Service, you agree to these terms.
We compare shipping rates and postage prices to help you find the best way to ship. Quotes are estimates based on live data from carriers and shipping software at the time of your request. Prices, services, and transit times can change, and final pricing is always determined by the carrier or postage vendor you buy from. We are not a carrier, postage vendor, or shipping broker, and we do not sell, print, or fulfill shipping labels.
The Service is free for personal and business use, including through AI assistants. You agree not to disrupt the Service, place excessive automated load on it, attempt to circumvent rate limits, misrepresent the Service or its data as your own, or use it for any unlawful purpose. We may limit, suspend, or block access that we reasonably believe violates these terms.
Some links on the Service go to third-party postage and shipping vendors, and we may earn a commission when you sign up or purchase through them. This never changes the rates we show, which come from carrier data. See our disclosure for details.
The Service is provided “as is” without warranties of any kind, express or implied, including accuracy, availability, or fitness for a particular purpose. Always confirm final pricing with the vendor before purchasing postage.
To the maximum extent permitted by law, OnlineShippingCalculator.com and its operators are not liable for any indirect, incidental, or consequential damages arising from your use of the Service, including decisions made based on rate estimates. Our total liability for any claim relating to the Service will not exceed one hundred US dollars ($100).
How we handle data is described in our privacy policy, including what our APIs log and for how long.
We may update these terms from time to time; the latest version will always be at this page with its date above. Continued use of the Service after a change means you accept the updated terms.
