Terms of Service

Effective date: April 17, 2026

Note: these terms are informational, not legal advice. Consult your own counsel to understand your rights and obligations.

What these terms cover

These terms govern your use of the rateship.io website (the "site") and the rateship npm package (the "SDK"). By using either, you agree to these terms. If you don't agree, don't use them.

The SDK

The SDK is free and open-source, released under the MIT License. The license governs your rights to use, modify, and redistribute the code. It also contains the warranty disclaimer and liability limit that standard MIT-licensed software carries. These terms do not override anything in the MIT License.

You bring your own providers

• The SDK talks to EasyPost, Shippo, and ShipEngine using API keys you provide. Your relationship with each of those providers is governed by their terms of service, not ours.
• Label charges go to your provider account, not to us. We don't process payments, take custody of shipments, or act as a merchant of record.
• You're responsible for complying with each provider's terms. You represent that you have the right to use the API keys you pass to the SDK.

No hosted service

There is no RateShip account, dashboard, or hosted API. The site is documentation only; the SDK runs entirely on your own infrastructure. Rate accuracy, delivery times, and label availability are determined by the providers, we have no visibility into or control over them.

Acceptable use

Don't use the SDK or the site to:

• Violate applicable laws or third-party rights.
• Abuse a shipping provider's API in ways that would violate their terms (excessive scraping, credential sharing, misrepresenting identity, etc.).
• Scrape or mirror the docs site at a rate that places an unreasonable load on it.

No warranty

The SDK and site are provided "as is" and "as available," without warranties of any kind, express or implied. We don't guarantee accuracy of third-party rates, label availability, or uninterrupted site availability.

Limitation of liability

To the fullest extent permitted by law, we're not liable for indirect, incidental, special, punitive, or consequential damages of any kind, nor for actions or omissions by the shipping providers you call through the SDK. Because the SDK is free, our total liability is limited to zero dollars.

Changes

We may update these terms. Material changes will be posted on this page with a new effective date. Continued use after a change means you accept the update.
